Additional RAM for your computer. Installing, configuring and overclocking RAM

RAM is a capricious madam. She is not capable of much on her own, but she is extremely picky in choosing a mate: they say, don’t give me just anyone. Moreover, the quarrelsome nature of the RAM can make itself felt both immediately after the neighbor appears, and over time. For example, when you urgently need a computer.

Today we will dot all the “E”s in the questions of whether it is possible to combine different strips RAM on one PC, is it possible collaboration RAM different generations, types, volume, frequency and manufacturers. And if possible, then under what conditions.

Connection of generations

My motherboard has generation RAM slotsDDR2 andDDR3. Is it possible to install dies of both types on it?

The clear answer is no. Such hybrid modifications of motherboards were produced at the turn of the transition from the DDR2 to DDR3 standard. They are capable of working with either DDR2 memory with frequencies of 667, 800 and 1066 mHz, or with DDR3 memory with frequencies of 1066 and 1333 mHz. If you install DDR2 and DDR3 together on such a board (of course, in slots of their own type), the computer will not start.

DDR3 + DDR3L = ?

Is it possible to sharing two modulesRAM, one of whichDDR-3, and the second -DDR-3L? How is the second different from the first?

DDR3 memory long time was the only choice. And only shortly before DDR4 entered the market, it saw the light of day. new modification– DDR3L. The letter “L” in the name of the latter means “low voltage”.

The DDR3L RAM is powered by a voltage of 1.35 V, and its predecessor consumes 1.5 V - this is their main difference. Externally, both types of planks look the same.

The DDR3L standard is fully compatible with motherboards and processors designed for DDR3, but not vice versa. Thus, Intel processors with Skylake S microarchitecture do not officially support DDR 3, although they support DDR 3L.

Sharing modules of both types is sometimes possible, but not desirable. All memory installed in the slots of one motherboard, is powered by the same voltage level, so only one of the strips will be in optimal conditions. Computers with this RAM configuration are usually unstable, and some do not turn on at all.

Volumes and channels

I want to install RAM in all 4 slots, does the capacity of each module matter? Which combination will work faster - 4 2 GB sticks, 2 4 GB sticks or 1 8 GB stick?

The only requirement for the amount of RAM is that it does not exceed the maximum allowable, otherwise the computer will not turn on or part of the memory will remain unused. The claim that all RAM should be of the same capacity is a myth. There is never too much of it, so bet as much as you want.

All modern desktops and many laptops support multi-channel RAM mode. With this method of organization, memory is accessed not along one, but along several parallel lines, which significantly increases the performance of the machine.

Motherboards with four RAM slots (the most common type) operate in dual-channel mode, that is, they have 2 connectors for 1 channel.

Of the three presented combinations, the fastest will be the second one - 2 4 GB sticks, if you distribute them one per channel. Why two and not four? Because the actual speed of data exchange between the controller and each RAM module is not the same, and the more sticks, the more time is spent synchronizing them.

For RAM modules to work in multi-channel mode, they must be:

• Same frequency.
• Approximately the same capacity (small differences are sometimes acceptable).
• One type (for example, DDR3 or DDR3L only).

And their total number must be even.

By the way, RAM slots of one channel are often made one color. But not always. To find out where they are located on your motherboard, it is better to look at its instructions.

Frequencies and timings

Can it be combined with different timings? If so, what frequency do they operate at?

Can. Each unit of RAM stores information about supported frequencies and timings internally (in the SPD chip). The memory controller reads this data and selects a mode in which all modules can operate. As a rule, these are the frequency and timings of the slowest one.

Various manufacturers

Is it necessary to buy RAM from the same manufacturer?

It is advisable to purchase RAM not just one brand, but factory sets of several modules. These devices have been jointly tested and are guaranteed to be able to work together.

It happens that RAM of the same brand and model, purchased separately, cannot “find a common language”. It also happens the other way around, when devices of different origins demonstrate excellent teamwork. Depending on your luck, the first option is rather an exception. Most often dies different manufacturers with similar characteristics are compatible.

Is it possible to combine different sticks of RAM in one computer? updated: April 26, 2018 by: Johnny Mnemonic

RAM is used to temporarily store data necessary for the operation of the operating system and all programs. There should be enough RAM; if there is not enough, the computer starts to slow down.

The board with memory chips is called a memory module (or stick). Memory for a laptop, except for the size of the slots, is no different from memory for a computer, so when choosing, follow the same recommendations.

For office computer One 4 GB DDR4 stick with a frequency of 2400 or 2666 MHz is enough (costs almost the same).
RAM Crucial CT4G4DFS824A

For multimedia computer(movies, simple games) it is better to take two 4 GB DDR4 sticks with a frequency of 2666 MHz, then the memory will work in a faster dual-channel mode.
RAM Ballistix BLS2C4G4D240FSB

For gaming computer In the middle class, you can take one 8 GB DDR4 stick with a frequency of 2666 MHz so that in the future you can add another one, and it would be better if it is a simpler running model.
RAM Crucial CT8G4DFS824A

And for a powerful gaming or professional PC, you need to immediately take a set of 2 DDR4 8 GB sticks, and a frequency of 2666 MHz will be quite sufficient.

2. How much memory is needed

For an office computer designed for working with documents and accessing the Internet, one 4 GB memory stick is sufficient.

For a multimedia computer that can be used to watch high-quality videos and undemanding games, 8 GB of memory is sufficient.

For a mid-range gaming computer, the minimum option is 8 GB of RAM.

A powerful gaming or professional computer requires 16 GB of memory.

A larger amount of memory may only be needed for very demanding professional programs and is not needed by ordinary users.

Memory capacity for older PCs

If you decide to increase the memory on your old computer, be aware that 32-bit versions of Windows do not support more than 3 GB of RAM. That is, if you install 4 GB of RAM, the operating system will see and use only 3 GB.

As for 64-bit versions of Windows, they will be able to use all the installed memory, but if you have old computer or have an old printer, then they may not have drivers for these operating systems. In this case, before purchasing memory, install 64 bit version Windows and check if everything works for you. I also recommend looking at the website of the motherboard manufacturer and seeing what volume of modules and total amount of memory it supports.

Please also note that 64-bit operating systems consume 2 times more memory, for example, Windows 7 x64 takes about 800 MB for its needs. Therefore, 2 GB of memory for such a system will not be enough, preferably at least 4 GB.

Practice shows that modern operating systems Windows 7,8,10 are fully operational with a memory capacity of 8 GB. The system becomes more responsive, programs open faster, and jerks (freezes) disappear in games.

3. Memory types

Modern memory has DDR type SDRAM and is constantly being improved. So DDR and DDR2 memory is already obsolete and can only be used on older computers. DDR3 memory is no longer advisable to use on new PCs; it has been replaced by the faster and more promising DDR4.

Please note that the selected memory type must be supported by the processor and motherboard.

Also, new processors, for compatibility reasons, can support DDR3L memory, which differs from regular DDR3 in reduced voltage from 1.5 to 1.35 V. Such processors will be able to work with ordinary memory DDR3 if you already have it, but processor manufacturers do not recommend this due to increased degradation of memory controllers designed for DDR4 with an even lower voltage of 1.2 V.

Memory type for older PCs

Outdated DDR2 memory costs several times more than more modern memory. A 2 GB DDR2 stick costs 2 times more, and a 4 GB DDR2 stick costs 4 times more than a DDR3 or DDR4 stick of the same size.

Therefore, if you want to significantly increase the memory on an old computer, then perhaps the best option would be to switch to a more modern platform by replacing the motherboard and, if necessary, a processor that will support DDR4 memory.

Calculate how much it will cost you; perhaps a profitable solution would be to sell the old motherboard with old memory and purchase new, albeit not the most expensive, but more modern components.

The motherboard connectors for installing memory are called slots.

Each memory type (DDR, DDR2, DDR3, DDR4) has its own slot. DDR3 memory can only be installed in a motherboard with DDR3 slots, DDR4 - with DDR4 slots. Motherboards supporting old memory DDR2 is no longer produced.

5. Memory characteristics

The main characteristics of memory on which its performance depends are frequency and timings. Memory speed does not have as strong an impact on the overall performance of the computer as the processor. However, you can often get faster memory for not much more. Fast memory needed primarily for powerful professional computers.

5.1. Memory frequency

Frequency has highest value on memory speed. But before purchasing it, you need to make sure that the processor and motherboard also support the required frequency. Otherwise, the actual memory operating frequency will be lower and you will simply overpay for something that will not be used.

Inexpensive motherboards support lower maximum memory frequencies, for example for DDR4 it is 2400 MHz. Medium and high class can support memory with higher frequency (3400-3600 MHz).

But with processors the situation is different. Older processors with support DDR memory 3 can support memory with a maximum frequency of 1333, 1600 or 1866 MHz (depending on model). For modern processors that support DDR4 memory, the maximum supported memory frequency may be 2400 MHz or higher.

Intel 6th generation and higher processors and AMD Ryzen processors support DDR4 memory at 2400 MHz or higher. Moreover, their lineup includes not only powerful expensive processors, but also mid-range and budget-class processors. Thus, you can build a computer on the most modern platform with an inexpensive processor and DDR4 memory, and in the future change the processor and get the highest performance.

The main memory today is DDR4 2400 MHz, which is supported by the most modern processors, motherboards and costs the same as DDR4 2133 MHz. Therefore, purchasing DDR4 memory with a frequency of 2133 MHz today does not make sense.

You can find out what memory frequency a particular processor supports on the manufacturers’ websites:

By model number or serial number it is very easy to find all the characteristics of any processor on the website:

Or simply enter your model number in search engine Google or Yandex (for example, “Ryzen 7 1800X”).

5.2. High Frequency Memory

Now I want to touch on another interesting point. On sale you can find RAM at a much higher frequency than can be supported by any modern processor(3000-3600 MHz and above). Accordingly, many users are wondering how this can be?

It's all about a technology developed by Intel, eXtreme Memory Profile (XMP). XMP allows memory to last longer high frequency, than the processor officially supports. XMP must be supported by both the memory itself and the motherboard. High frequency memory simply cannot exist without support for this technology, but not all motherboards can boast of its support. These are mainly more expensive models above the middle class.

The essence of XMP technology is that the motherboard automatically increases the frequency of the memory bus, due to which the memory begins to operate at its higher frequency.

AMD has a similar technology called AMD Memory Profile (AMP), which was supported by older motherboards for AMD processors. These motherboards usually also supported XMP modules.

Purchasing more expensive memory with a very high frequency and a motherboard with XMP support makes sense for very powerful professional computers equipped with a top-end processor. In a middle-class computer, this will be wasted money, since everything will depend on the performance of other components.

In games, the memory frequency has a small impact and there is no point in overpaying; it will be enough to go for 2400 MHz, or 2666 MHz if the difference in price is small.

For professional applications, you can take memory with a higher frequency - 2666 MHz or, if you want and have funds, 3000 MHz. The difference in performance here is greater than in games, but not dramatic, so there is no particular point in pushing the memory frequency.

Let me remind you once again that your motherboard must support memory at the required frequency. In addition, sometimes Intel processors become unstable at memory frequencies above 3000 MHz, and for Ryzen this limit is around 2900 MHz.

Timings are the delays between read/write/copy operations of data in RAM. Accordingly, the fewer these delays, the better. But timings have a much smaller impact on memory speed than its frequency.

There are only 4 main timings that are indicated in the characteristics of memory modules.

Of these, the most important is the first number, which is called latency (CL).

Typical latency for DDR3 1333 MHz memory is CL 9, for higher frequency DDR3 memory is CL 11.

Typical latency for DDR4 2133 MHz memory is CL 15, for DDR4 memory with higher frequencies is CL 16.

You should not purchase memory with a latency higher than specified, as this indicates an overall low level of its technical characteristics.

Typically, memory with lower timings is more expensive, but if the price difference is not significant, then memory with lower latency should be preferred.

5.4. Supply voltage

Memory may have different supply voltages. It can be either standard (generally accepted for a certain type of memory), or increased (for enthusiasts) or, conversely, decreased.

This is especially important if you want to add memory to your computer or laptop. In this case, the voltage of the new strips should be the same as the existing ones. Otherwise, problems may occur, since most motherboards cannot display different voltage for different modules.

If the voltage is set to a level with a lower voltage, then others may not have enough power and the system will not work stably. If the voltage is set to a level with a higher voltage, then the memory designed for a lower voltage may fail.

If you are collecting new computer, then this is not so important, but to avoid possible compatibility problems with motherboard and replacing or expanding memory in the future, it is better to choose sticks with a standard supply voltage.

The memory, depending on the type, has the following standard supply voltages:

• DDR - 2.5 V
• DDR2 - 1.8 V
• DDR3 - 1.5 V
• DDR3L - 1.35 V
• DDR4 - 1.2 V

I think you noticed that there is DDR3L memory in the list. This is not a new type of memory, but regular DDR3, but with a reduced supply voltage (Low). This is the kind of memory needed for Intel processors 6th generation and above, which support both DDR4 and DDR3 memory. But in this case it is better to assemble the system using new memory DDR4.

6. Marking of memory modules

Memory modules are marked depending on the type of memory and its frequency. The marking of DDR memory modules begins with PC, followed by a number indicating the generation and speed in megabytes per second (MB/s).

Such markings are inconvenient to navigate; it is enough to know the type of memory (DDR, DDR2, DDR3, DDR4), its frequency and latency. But sometimes, for example on ad sites, you can see markings copied from the strip. Therefore, so that you can get your bearings in this case, I will give the markings in classic form, indicating the memory type, its frequency and typical latency.

DDR - obsolete

• PC-2100 (DDR 266 MHz) - CL 2.5
• PC-2700 (DDR 333 MHz) - CL 2.5
• PC-3200 (DDR 400 MHz) - CL 2.5

DDR2 - obsolete

• PC2-4200 (DDR2 533 MHz) - CL 5
• PC2-5300 (DDR2 667 MHz) - CL 5
• PC2-6400 (DDR2 800 MHz) - CL 5
• PC2-8500 (DDR2 1066 MHz) - CL 5

DDR3 - obsolete

• PC3-10600 (DDR3 1333 MHz) - CL 9
• PC3-12800 (DDR3 1600 MHz) - CL 11
• PC3-14400 (DDR3 1866 MHz) - CL 11
• PC3-16000 (DDR3 2000 MHz) - CL 11

• PC4-17000 (DDR4 2133 MHz) - CL 15
• PC4-19200 (DDR4 2400 MHz) - CL 16
• PC4-21300 (DDR4 2666 MHz) - CL 16
• PC4-24000 (DDR4 3000 MHz) - CL 16
• PC4-25600 (DDR4 3200 MHz) - CL 16

DDR3 and DDR4 memory may have a higher frequency, but only top processors and more expensive motherboards can work with it.

7. Design of memory modules

Memory sticks can be single-sided, double-sided, with or without radiators.

7.1. Chip placement

Chips on memory modules can be placed on one side of the board (single-sided) or on both sides (double-sided).

This doesn't matter if you are purchasing memory for a new computer. If you want to add memory to an old PC, then it is advisable that the arrangement of chips on the new stick be the same as on the old one. This will help avoid compatibility issues and increase the likelihood of memory operating in dual-channel mode, which we will talk about later in this article.

Now on sale you can find many memory modules with aluminum radiators of various colors and shapes.

The presence of heatsinks can be justified on DDR3 memory with a high frequency (1866 MHz or more), since it heats up more. At the same time, ventilation must be well organized in the housing.

Modern DDR4 RAM with a frequency of 2400, 2666 MHz practically does not heat up and the radiators on it will be purely decorative. They can even get in the way, because after a while they become clogged with dust, which is difficult to clean out of them. In addition, such memory will cost slightly more. So, if you want, you can save on this, for example, by taking excellent Crucial 2400 MHz memory without heatsinks.

Memory with a frequency of 3000 MHz or more also has an increased supply voltage, but it also does not heat up very much and in any case there will be heatsinks on it.

8. Memory for laptops

Memory for laptops differs from memory for desktop computers only in the size of the memory module and is labeled SO-DIMM DDR. Just like for desktop computers, memory for laptops has types DDR, DDR2, DDR3, DDR3L, DDR4.

In terms of frequency, timings and supply voltage, memory for laptops does not differ from memory for computers. But laptops only come with 1 or 2 memory slots and have stricter maximum capacity limits. Be sure to check these parameters before choosing memory for specific model laptop.

9. Memory operating modes

The memory can operate in Single Channel, Dual Channel, Triple Channel or Quad Channel mode.

In single-channel mode, data is written sequentially to each module. In multi-channel modes, data is written in parallel to all modules, which leads to a significant increase in the speed of the memory subsystem.

Single-channel memory mode is limited only to hopelessly outdated motherboards with DDR memory and the first models with DDR2.

All modern motherboards support dual-channel memory mode, while three-channel and quad-channel modes are supported only by a few models of very expensive motherboards.

The main condition for dual-channel mode operation is the presence of 2 or 4 memory sticks. Three-channel mode requires 3 or 6 memory sticks, and four-channel mode requires 4 or 8 memory sticks.

It is desirable that all memory modules are the same. Otherwise, dual-channel operation is not guaranteed.

If you want to add memory to an old computer and your motherboard supports dual-channel mode, try to choose a stick that is as identical in all respects as possible. It is best to sell the old one and buy 2 new identical strips.

In modern computers, memory controllers have been moved from the motherboard to the processor. Now it is not so important that the memory modules are the same, since the processor will still be able to activate dual-channel mode in most cases. This means that if in the future you want to add memory to a modern computer, you will not necessarily need to look for exactly the same module; you just need to choose the one that is most similar in characteristics. But I still recommend that the memory modules be the same. This will give you a guarantee of its fast and stable operation.

With the transfer of memory controllers to the processor, 2 more modes of dual-channel memory operation appeared - Ganged (paired) and Unganged (unpaired). If the memory modules are the same, the processor can work with them in Ganged mode, as before. If the modules differ in characteristics, the processor can activate the Unganged mode to eliminate distortions in working with memory. In general, the memory speed in these modes is almost the same and makes no difference.

The only downside to dual-channel mode is that multiple memory modules are more expensive than one of the same size. But if you are not very strapped for money, then buy 2 sticks, the memory speed will be much higher.

If you need, say, 16 GB of RAM, but you can’t afford it yet, then you can buy one 8 GB stick so that you can add another one of the same kind in the future. But it is still better to purchase two identical strips at once, since later you may not be able to find the same one and you will encounter a compatibility problem.

10. Memory module manufacturers

One of best ratios price/quality today is the memory of the impeccably proven Crucial brand, which has modules from budget to gaming (Ballistix).

Competing with it is the well-deserved Corsair brand, whose memory is somewhat more expensive.

As an inexpensive but high-quality alternative, I especially recommend the Polish brand Goodram, which has bars with low timings for low price(Play line).

For an inexpensive office computer, simple and reliable memory made by AMD or Transcend will be sufficient. They have proven themselves to be excellent and there are practically no problems with them.

In general, the Korean companies Hynix and Samsung are considered leaders in memory production. But now modules of these brands are mass-produced in cheap Chinese factories, and among them there are a lot of fakes. Therefore, I do not recommend purchasing memory from these brands.

An exception may be Hynix Original and Samsung Original memory modules, which are manufactured in Korea. These strips are usually blue, their quality is considered better than those made in China and the guarantee for them is slightly higher. But in terms of speed characteristics, they are inferior to memory with lower timings from other quality brands.

Well, for enthusiasts and fans of modding there are affordable overclocking brands GeIL, G.Skill, Team. Their memory has low timings, high overclocking potential, an unusual appearance and costs a little less than the well-promoted Corsair brand.

There is also a wide range of memory modules on sale from the very popular manufacturer Kingston. Memory sold under the budget Kingston brand has never been of high quality. But they have a top-end HyperX series, which is deservedly popular, which can be recommended for purchase, but is often overpriced.

11. Memory packaging

It is better to purchase memory in individual packaging.

It is usually of higher quality and is much less likely to be damaged in transit than memory that comes loose.

12. Increase memory

If you are planning to add memory to an existing computer or laptop, then first find out what the maximum memory capacity and total memory capacity is supported by your motherboard or laptop.

Also check how many memory slots are on the motherboard or laptop, how many of them are occupied and what kind of memory sticks are installed in them. It's better to do it visually. Open the case, take out the memory sticks, examine them and write down all the characteristics (or take a photo).

If for some reason you don’t want to get into the case, you can view the memory parameters in the program on the SPD tab. This way you won't know if the stick is single-sided or double-sided, but you can find out the memory characteristics if there is no sticker on the stick.

There is a base and effective memory frequency. The CPU-Z program and many similar ones show base frequency, it must be multiplied by 2.

Once you know how much memory you can increase, how many free slots are available, and what kind of memory you have installed, you can begin to explore the possibilities of increasing memory.

If all memory slots are occupied, then the only way to increase memory is to replace existing memory sticks with new ones of larger capacity. And old planks can be sold on an advertisement site or exchanged at a computer store when purchasing new ones.

If there are free slots, then you can add new memory sticks to the existing ones. In this case, it is desirable that the new strips be as close as possible to the characteristics of those already installed. In this case, you can avoid various compatibility problems and increase the chances that the memory will work in dual-channel mode. To do this, the following conditions must be met, in order of importance.

1. The memory type must match (DDR, DDR2, DDR3, DDR3L, DDR4).
2. The supply voltage for all strips must be the same.
3. All planks must be single-sided or double-sided.
4. The frequency of all bars must match.
5. All strips must be of the same volume (for dual-channel mode).
6. The number of strips must be even: 2, 4 (for dual-channel mode).
7. It is desirable that the latency (CL) matches.
8. It is desirable that the strips are from the same manufacturer.

The easiest place to start choosing is with the manufacturer. Choose in the online store catalog strips of the same manufacturer, volume and frequency as installed in yours. Make sure that the supply voltage matches and check with your consultant whether they are single-sided or double-sided. If the latency also matches, then generally good.

If you were unable to find strips from the same manufacturer with similar characteristics, then choose all the others from the list of recommended ones. Then again look for strips of the required volume and frequency, check the supply voltage and check whether they are single-sided or double-sided. If you are unable to find similar planks, then look in another store, catalog or ad site.

The best option is always to sell all the old memory and buy 2 new identical sticks. If the motherboard does not support the brackets of the required volume, you may have to buy 4 identical brackets.

13. Setting up filters in the online store

1. Go to the “RAM” section on the seller’s website.
2. Select recommended manufacturers.
3. Select the form factor (DIMM - PC, SO-DIMM - laptop).
4. Select the memory type (DDR3, DDR3L, DDR4).
5. Select the required volume of slats (2, 4, 8 GB).
6. Select the maximum frequency supported by the processor (1600, 1866, 2133, 2400 MHz).
7. If your motherboard supports XMP, add higher frequency memory (2666, 3000 MHz) to the selection.
8. Sort the selection by price.
9. Consistently look through all items, starting with the cheapest ones.
10. Select several strips that match the frequency.
11. If the price difference is acceptable to you, take sticks with a higher frequency and lower latency (CL).

Thus, you will get the optimal price/quality/speed ratio of memory at the lowest possible cost.

Not everyone knows that simply installing RAM into a computer is not enough. It’s useful to set it up and overclock it. Otherwise, it will provide the minimum efficiency specified in the parameters. Here it is important to consider how many strips to install, how to distribute them among slots, and how to set parameters in the BIOS. Below you will find tips on installing RAM, learn how to properly install, configure, etc.

The first question that arises when users want to increase the performance and speed of RAM is whether it is possible to install memory modules from different manufacturers that differ in frequency into a computer? When deciding how to install RAM in a computer, purchase better modules one production, one frequency.

Theoretically, if you install modules of different frequencies, the RAM works, but at the characteristics of the slowest module. Practice shows that incompatibility problems often arise: the PC does not turn on, the OS crashes.

Therefore, if you plan to install several strips, buy a set of 2 or 4 modules. In identical strips, chips have the same parameters overclocking potential.

The usefulness of multi-channel mode

A modern computer supports multi-channel RAM operation, with a minimum of 2 channels equipped. There are processor platforms with three-channel mode, and others with eight memory slots for four-channel mode.

When dual-channel mode is enabled, the processor's performance is increased by 5–10%, and the graphics accelerator's performance is increased by up to 50%. Therefore, when assembling even an inexpensive gaming device, it is recommended to install at least two memory modules.

If you are connecting two RAM modules, and the board installed in the computer is equipped with 4 DIMM slots, follow the installation order. To enable dual-channel mode, install modules in the computer, alternating the board connectors through one, i.e. place them in 1 and 3 or use connectors 2 and 4. The second option is often convenient, because often the first RAM slot is blocked by the processor cooler. If the radiators are low profile, this problem will not arise.

You can check whether the dual-channel mode is connected through the AIDA64 application. Go to the “Test cache and memory” item. The utility will also help you calculate the performance of RAM before overclocking, observe how the memory and its characteristics have changed after the overclocking procedure.

Setting frequency and timings

To overclock RAM, you need to know how. When you just install RAM in your computer, the RAM will most likely run at the minimum possible frequency, available in the technical parameters of the processor. The maximum frequency needs to be set, configured through the motherboard BIOS, or manually, there is a way to speed up Intel technology XMP, supported by almost all boards, even AMD.

When you manually set it to 2400 MHz, the memory will operate at standard timings for this frequency, which are 11-14-14-33. But HyperX Savage modules cope with stable operation at lower timings at a high frequency of 2400 MHz; this ratio (low timings with high frequencies) is a guarantee of high RAM performance.

A useful technology developed by Intel - Extreme Memory Profile - allows you to avoid manually setting each timing; in two clicks you select the optimal profile from those prepared by the manufacturer.

Memory overclocking

We said above that installing, even correctly, the RAM strips is not enough. Having turned on the two-channel, or better yet, four-channel mode, select the optimal frequency settings that correlate with the timing. Remember, first of all, that no one will give you a guarantee of overclocking; you will be able to overclock one memory perfectly, but not successfully overclock another memory. But don’t be afraid that the memory may fail when you overclock it: if it’s turned up too high, it will simply not start.

What to do if overclocking is unsuccessful? Typically, motherboards are equipped with an auto-reset function, which you can use when the computer does not start several times after overclocking. You can also do it manually by using the Clear CMOS jumper (aka JBAT).

The frequency is selected experimentally, and the supply voltage and timings are also set. Of course, there is no guarantee that the selected ratio will be better than the maximum XMP profile. Often, with maximum frequency overclocking, you have to increase the timings.

Be sure to test your result using the AIDA64 Cache & Memory Benchmark utility. Overclocking can lead to a drop in speed, becoming almost useless. Typically, low-frequency versions have higher potential than high-end ones.

Installing memory and overclocking it are simple processes, especially when the RAM supports ready-made XMP profiles. Remember that it is more practical to buy RAM for your computer as a kit in order to get a performance boost from dual-channel mode, not only from overclocking. We recommend purchasing a low-profile RAM for your computer to avoid incompatibility when using a large-sized processor cooler. Follow the tips, then you can overclock the RAM to maximum speed.

RAM is one of the most important components that affects computer performance. Therefore, adding it is one of the most common “upgrades”. The first sign that there is not enough RAM is slow operation personal computer. The PC stops coping with many tasks that the installed software, cannot provide correct and Good work new games.

The most budget-friendly way to solve this problem– install additional RAM. This can be done both on a desktop computer and on most laptop models. Before proceeding to the manual correct actions, it is worth mentioning that desktop iMac computers can only install RAM designed for laptops.

The first thing you need to do is determine what type of RAM is installed on your computer in order to install a new one or replace it entirely. This will depend on the type of motherboard. To understand this, you can open the case or look at the attached documentation. If the necessary documents are not available, you should go to the manufacturer’s website.

There are only three types of RAM, DRR, DDR2 and DDR3. The vast majority of modern desktop computers are equipped with the last two types of RAM. The essence of identifying RAM is its speed and throughput. It is very important to make sure that both characteristics will fully correspond to the factory parameters of the motherboard. These parameters are also called identifiers. You can cite following examples determination of compliance. An ID such as PC3 12800 means that the maximum bandwidth is equivalent to 12.8 GB. Another identifier, for example, DDR3 1800, tells us that the speed is 1800 MHz.

Slots

The next step to installing memory is to determine the number of slots intended for RAM modules. Most motherboards have a limit on the amount of RAM. And this indicator will not depend on how many connectors it has.

Anyway the best option the purchase will be prompt SDRAM memory. If you choose RAM, you will have to purchase two or four modules. Example: to get an “extra” of 8 GB of RAM, you need to take two 4 GB modules or four 2 GB modules. It is important that they all have identical parameters that we mentioned above (we are talking about speed and throughput). If you ignore this issue, the overall performance of the computer may decrease significantly, since the system will configure itself in accordance with the minimum factory values ​​​​recorded in the PC. It is very important to double-check the motherboard's capabilities.

Preparation

Before installing memory, you need to turn off not only the computer, but also all peripheral devices - monitor, mouse and keyboard. Only after this can you open the case and then place it on a table or floor so as to gain maximum access to the motherboard.

It is important to completely eliminate the possible occurrence of static charges. This may damage some computer components. You can get rid of charges in two ways:

• touch the body of a switched off computer while it is connected to the network;
• Wear an antistatic wrist strap.

Also, do not stand on the surface of a carpet or rug while work in progress with components system unit PC.

Start installation

You need to find the motherboard connectors. In most cases, there will be either two or four such slots. Finding them is easy. They are located next to the processor. If you can’t find the connectors, you can use the documents for the motherboard. But the easiest way is to just look where exactly the old RAM modules are located.

Removing the video card

There are some motherboards whose design is such that the video card will significantly interfere with the correct installation of RAM. This means that before installing the memory, it will need to be removed. One or two power cords can be connected to the video card. You should pay attention to what the mounting diagram is.

Usually there are levers on the cords, after pressing which the cord can be easily pulled out correctly. The next step is to unscrew the screws connecting the video card to the motherboard. Most devices have a latch or retainer located on the socket PCI Express. It is to this socket that the video card is attached, and it serves to ensure that the card can be connected very tightly to the connector. This is necessary, since this is the only way to provide support from the front side. WITH reverse side Screws serve as fastenings. The latch will need to be moved back enough so that you can easily remove the video card. It should be remembered that each procedure is carried out as carefully as possible, the card is pulled out and not pulled out of the slot from the front side. There is no need to apply force.

Now we have access to RAM. But there is one more point. If the computer has been in use for a long time, then removing the video card gives us a chance to clean it. Only a soft brush should be used. There is absolutely no need to disassemble the cooling system of the video card, since its design is very fragile. You can carefully clean only the fan, but even here, using force can lead to damage.

Insert the memory module

Let's return to RAM. Then you need to pull out the RAM module by opening the clips on both sides. The new module is removed from the packaging, but it must be held in such a way as not to touch the contacts on the bottom and the microcircuits located on the sides.

The module is inserted so that its groove clearly coincides with the protrusion in the motherboard connector. To do this, you need to lightly press the module, which, after it enters the connector, must be fixed using the connectors.

When performing this procedure, you must ensure that installation is done in the correct slots. The latter are marked on the motherboard, or they are different from each other in color. But it's still worth looking through the documentation again. According to the described scheme, each RAM module is installed.

We complete the process

Before closing the housing, it is highly advisable to completely clean the surface of the housing and all components using a compressed air supply device. This will increase air circulation inside the case, which, in turn, will increase the performance of the computer.

After cleaning, you need to close the computer case. There is no need to turn it on if the case is open, this will negatively affect the cooling process. Peripheral devices must be connected to a non-working computer.

Checking the result

Then you need to turn on the PC. Some systems start a process to test the functionality of components after the configuration has been changed. This is how you can ensure that you were able to install the new RAM correctly.

If the computer has not started scanning, you can do it yourself - directly in Windows. It's easy to do. You need to press Win+Pause/Break, then the “System” window will open. There is also Alternative option opening a window through Explorer or the Start menu. The System window is located in the Properties section of the My Computer folder. You can get here by clicking right click mouse over the folder. In "Properties" there is detailed information about the RAM that was installed by the user.

Different operating systems will display RAM size differently. Some systems are able to reserve a particular amount of memory for specific needs. For example, if the amount of new RAM was 2 GB, then the PC may display it as 1.99 GB.

If you can’t do independent testing, you can use one of the existing utilities. They are provided free of charge and can be downloaded online.

Correctly installed RAM will increase the performance of your computer several times. Improvements will be felt within the first minutes after launching the game or any software.

If your computer works slowly, freezes when working with programs and playing games, then one of the optimal ways To increase its performance at the hardware level is to install additional RAM on the computer. In this article we will look at step by step the process of adding or replacing RAM.

Selecting the desired type of RAM

Before you go to the store to buy a new memory module, you need to find out what type of RAM your motherboard supports. There are the following types of RAM: DDR, DDR2, DDR3, DDR3 L and the new type DDR 4. They They vary in size, so if you buy the wrong type, it simply won't fit into the connector. There is also a division into form factors DIMM (for desktop computers) and SODIMM (for laptops).

To find out the type, you need to carefully read the instructions for the motherboard. If you already have memory modules installed, take one of them and look for the settings sticker. It shows the DDR type. Most modern computers have DDR2 and DDR3 memory installed.

Counting the number of RAM slots on the motherboard

The number of slots for memory modules on a motherboard can be 2,4,6,8, and even more on a server motherboard. Most motherboards have 2-4 connectors. You should pay attention to the maximum amount of memory that your motherboard supports.

Choosing a manufacturer

Many companies are developing RAM. The results of their work differ in both price and quality. We do not recommend purchasing memory from little-known manufacturers.

IN last years The following manufacturers are popular:

We purchase RAM

When going shopping at a specialized computer store, you need to know exactly what RAM you need and whether it will be compatible with.

Preparing to install RAM

Step 1. Turn off the computer's power. Disconnect all cables and cords connected to the back of the case.

(Monitor, mouse, keyboard, etc.)

Step 2. Remove the side cover from the housing. Place the computer case in such a way that it is convenient to work with it. It will be most convenient if you lay it on its side. Gain access to the motherboard by carefully moving away the nearby wires.

Step 3. Next, you should get rid of static charges. They can damage installed components on the motherboard. To do this, simply touch the case or battery with your hand. For some, this advice may seem ridiculous, someone will say that nothing will happen and nothing will be damaged, but as they say, “God protects the best,” so it’s better to play it safe and listen to the advice.

Step 4. Locate the RAM slots on the motherboard. In modern boards, manufacturers make 2 or 4 connectors. These are identical in size and parallel to each other. You can see what they look like in the photo below.

Step 5. If you are replacing old memory with new one, then you need to remove the old module. Gently press the two white outer latches. The module will come free and can be easily removed.

Step 6. Take a new memory stick, being careful not to touch the microcircuits and contacts located on it.

Basic recommendations applicable to all types and types of memory:
– it is best to install DIMM modules with the same memory capacity;
– the modules must match the operating frequency (Mhz), if you install modules with different frequencies work, then in the end they will all work at the frequency of the slowest memory;
– for installed RAM cards, it is advisable to combine timings and memory latencies (delays);
– it is better to select modules from one manufacturer and one model.

Some enthusiasts try to buy modules from the same batch, but this, it seems to me, is already a perversion!

These tips are not strictly followed; situations vary. If memory modules differ from each other in manufacturer, volume and operating frequency, this does not mean at all that they will not work. In this case, there are no special memory layout secrets - just installing them is enough.

There are also no special features when installing already outdated types of memory such as SDRAM (there is one rule - the more, the better).

But in modern computers, motherboards support special operating memory modes. It is in these modes that the speed RAM operation memory will be the most efficient. Therefore, to achieve best performance you should take into account the operating modes of DIMMs and their correct installation. Let's look at the most common RAM operating modes today.

RAM operating modes

SINGLE CHANELL MODE

Single Mode (single channel or asymmetric mode) – this mode is implemented when only one memory module is installed in the system or all DIMMs differ from each other in memory capacity, operating frequency or manufacturer. It doesn’t matter in which slots or what memory to install. All memory will run at the speed of the slowest memory installed.

If there is only one module, then it can be installed in any memory slot:

Two or three different memory modules can also be installed in any configuration:

This mode is more of a necessity when you already have RAM, and the first place is to increase the amount of memory and save money, and not to achieve best performance PC. If you are just buying a computer, of course, it is better to avoid such a memory installation.

DUAL CHANELL MODE

Dual Mode (two-channel or symmetrical mode) – the same amount of RAM is installed in each DIMM channel. Modules are selected according to operating frequency. On motherboards, the DIMM sockets for each channel are different colors. Next to them is written the name of the connector, and sometimes the channel number. The purpose of the connectors and their location along the channels must be indicated in the motherboard manual. The total memory volume is equal to the total volume of all installed modules. Each channel is served by its own memory controller. System performance increases by 5-10%.

Dual Mode can be implemented using two, three or four DIMMs.

If two identical RAM memory modules are used, they should be connected to the same connectors (the same color) from different channels. For example, install one module in the slot 0 channel A, and the second - into the connector 0 channel B:

That is, to enable the mode Dual Channel(interleaved mode) should be done the necessary conditions:
– the same configuration of DIMM modules is installed on each memory channel;
– memory is inserted into symmetrical channel connectors ( Slot 0 or Slot 1) .

Three memory modules are installed in a similar way - the total memory volumes in each channel are equal to each other (memory in the channel A equal in volume in the channel B):

And for four modules the same condition is satisfied. There are two parallel dual modes at work here:

TRIPLE CHANELL MODE

(three-channel mode) – the same amount of RAM is installed in each of the three DIMM channels. Modules are selected according to speed and volume. On motherboards that support three-channel memory mode, 6 memory connectors are usually installed (two for each channel). Sometimes there are motherboards with four connectors - two connectors make up one channel, the other two are connected to the second and third channels, respectively.

With six or three sockets, installation is as simple as with dual-channel mode. If there are four memory slots installed, three of which can work in, the memory should be installed in these slots.

(flexible mode) – allows you to increase the performance of RAM when installing two modules of different sizes, but identical in operating frequency. As in dual-channel mode, memory cards are installed in the same connectors of different channels. For example, if there are two memory sticks with a capacity of 512Mb and 1Gb, then one of them should be installed in the slot 0 channel A, and the second - into the slot 0 channel B:

In this case, the 512 MB module will work in dual mode with the 512 MB memory capacity of the second module, and the remaining 512 MB of the 1 GB module will work in single-channel mode.

That’s basically all the recommendations for combining RAM. Of course, there may be more layout options, it all depends on the amount of RAM, the motherboard model and your financial capabilities. Motherboards with support also appeared on sale four-channel mode memory performance - this will give you maximum computer performance!

Every computer owner has thought about improving it at least once. Some simply change the processor, others assemble and resolder the insides of the video card. But it's easier and cheaper to overclock a computer. This can be done by adding RAM to it. This method does not require special training or the expensive purchase of a new processor. But before you do practical solution question: “How to add RAM to a computer?”, you need to understand what it is and why it is needed.

What is RAM

Random access memory (RAM, RAM - random access memory, or RAM - Random Access Memory) is the place where all temporary data about the operation of programs is stored. Externally, the OP looks like several different microcircuits connected to the motherboard. It serves as temporary storage for all running programs and has a high speed of writing and reading data.

It should be noted that RAM is fundamentally different from hard disk memory. RAM stores information only for as long as the device is connected to power, i.e., as soon as the computer is turned off, all data on the RAM will be erased. Memory hard drive stores information until you delete it.

Modern RAM is very large and allows the computer to work on many tasks simultaneously. But their diversity confuses the inexperienced user. Let's try to figure out how to add RAM to a computer.

When should you change RAM?

Sometimes the user may not notice the signals that the equipment uses to notify that more effort is needed to perform routine tasks. It is not difficult to understand the signals; the main ones are visible. You need to change RAM if:

• the computer begins to slow down when executing programs;
• laptop or desktop computer takes a long time to load and load programs;
• Sites with “heavy” graphics and animation do not load;
• you need to install powerful games or complex programs, and also run several processes simultaneously.

So, is it possible to add RAM to a computer and in what ways can this be done?

Ways to increase RAM

It is quite possible to improve the performance of equipment; today there are three main ways to increase RAM on a computer:

• plank replacement method;
• Ready Boost installation;
• swap OP.

All methods are simple, even a beginner can handle them. However, each technique has its own nuances.

Hardware method: RAM modules

The first method involves installing new RAM sticks to replace the old ones. But not everything is so smooth here: the new brackets must be compatible with the motherboard as well as the processor. To use this method, you need to know exactly how to properly add RAM to your computer.

In general, the procedure is as follows:

• remove the cover of the system unit;
• find the RAM mounts on the motherboard;
• remove the old memory by pulling out the retaining clips;
• install new RAM;
• secure the bar with holders.

This method allows you to quickly and effectively add PC performance.

Hardware Method: Ready Boost System

The essence of the computer improvement method is that a flash drive is connected to the USB input, which will serve as a source of additional RAM. Special software (Ready Boost), supported by Microsoft Windows 7 and higher, can turn a USB drive into a data processing device.

Many users, when using the Ready Boost option, immediately try to take a larger drive, but this is not always necessary. The program can use external drives up to 256 GB on 64-bit Windows and only 4 GB on other OSes that support this feature.

Please note that when using this method, you should never disconnect the USB drive. The technique of adding RAM can be used as an auxiliary technique, but as a permanent solution you should choose something else.

Software method: page file

Is it possible to add RAM to a computer using only the PC's reserves? New versions of Windows have a very useful feature virtual memory. Essentially, these are hard drive reserves. To install, you need to go to: My computer - Properties - Additional settings, then select the "Performance" option, and in it - "Additional memory". Then you should set the required values. This method will benefit owners of older processors.

When it becomes clear how to add a RAM stick to a computer, connect a flash drive correctly, or use computer resources, you can immediately begin work, but first you should evaluate the advantages and disadvantages of each method. So, the most effective option would be to replace the RAM sticks.

Choosing RAM: compatibility with motherboard

Before purchasing new sticks, you should check the need to increase the performance of your computer. The technology may slow down various reasons, so first you need to check your laptop or PC for viruses, which eat up a huge share of the RAM. Next, you can clean your computer of unnecessary or outdated files and remove from startup those programs that are not needed when you turn on the PC. If everything is in order, you can select the appropriate device.

When choosing RAM, you must take into account that the motherboard must be compatible with it. In order to understand which temporary memory sticks are suitable for the motherboard, you need to:

• go to the motherboard manufacturer’s website;
• select the desired model;
• open the instructions;
• see the list of recommended options for OP strips.

Once the list of models has been studied, you can begin to select the appropriate option based on other parameters.

Technical parameters of RAM sticks

After determining compatibility, you should understand the necessary technical parameters. If you delve into all the details and follow the recommendations, solving the question of “how to install/add RAM” will not be difficult at all.

You should consider in detail the type and volume of memory, design features of the bar, operating modes, frequency and speed of operation, as well as some other parameters.

Type of memory

Today, there are several types of RAM: some of them are already outdated, others are so innovative that not all PCs support them.

The most sold (and therefore popular) are DDR3, or Double-Data-Rate, version three. Unlike the previous generation, DDR3 heats up less and has up to 2400 megahertz clock frequencies. Also this type RAM features low power consumption.

It is better not to mess with DDR1 and DDR2 memory standards, since they are outdated. There is also the newest type - DDR4, which has a clock frequency of up to 4200 megahertz. This type of memory may not be supported by all devices.

Form factor

Form factor is the design features of the RAM strip. There are strips for laptops (SO-DIMM) and for PCs (DIMM). The first ones are usually small in size and have fewer contacts. When choosing RAM for a PC or laptop, these characteristics must be supported by the motherboard.

Frequency and data transfer rate

Frequency and transmission speed are among the most important characteristics, which should be given Special attention when choosing. Frequency refers to the amount of information a computer can transmit in a given time. Accordingly, the higher the indicator, the better the performance of the PC. When choosing, you also need to take into account the parameters that the motherboard supports.

Memory operating modes

New RAMs have special modes that affect the data transfer speed. There are four main types of modes:

• Single Channel Mode - works when installing one bracket or with modules of different sizes; this is the slowest mode.
• Dual Mode is symmetrical; strips of equal volume are installed in the connectors, and the speed is doubled compared to the first mode.
• Triple Mode - uses three channels, and all have the same capacity, however, the data transfer speed of triple mode may be weaker than that of Dual.
• Flex Mode - flexible mode, involves installing two bars with different volumes, but the same frequency.

The most popular option today remains the symmetrical mode (Dual Mode).

Memory

The characteristic is as important as the data transfer speed, and remains one of the key ones today. The idea is extremely simple: the more memory, the faster the PC runs.

When choosing a RAM strip, you should take into account the goals and tasks for which the PC will be used in the future. If this is working with office programs and surfing the Internet, then 2 Gigabytes will be quite enough. For work that involves the use of heavy programs, such as graphic editors or video processing software, 4 GB of RAM will be enough. For modern games, 8 GB of RAM is sufficient. Today, RAM has been developed with a large capacity, but there are very few programs that allow you to use the full potential of such devices, and they are rarely used by average users.

Timings

Timing is the delay time between a command sent to the device and its execution. The parameter also determines how fast the computer or laptop will work. If the values ​​are large, and therefore the delay is significant, the RAM processes the information slowly. How less time delays, the higher the data processing speed.

There is also a direct relationship between timings and OP frequency. The higher the frequency values, the longer the timings. Therefore, when choosing, you should be guided by the golden mean.

Manufacturer

There are many manufacturers of PC components. The best option is to be guided by the brand's reputation, reviews of performance and reliability, and pricing policy companies. On this moment popular are:

• Corsair.
• Adata.
• Kingston.
• GOODRAM.
• Kingmax.
• Transcend.

Each manufacturer provides a wide range of models, so choose the RAM according to necessary characteristics, quality and price are a no-brainer. And in general, figuring out how to add RAM to a computer and how to choose RAM strips is not difficult. It is enough to be superficially oriented in the technical characteristics.

Important information

Before you begin self-installation, you must study all recommendations and instructions. The following tips are general:

1. When replacing slats, be sure to insert them all the way and secure them with clips. Otherwise, the computer will not see the components and will not boot.
2. When choosing the RAM frequency, consider the support of the board and OS. Otherwise, your computer may experience problems.
3. Even if new RAM is needed for powerful games, you shouldn’t spend your entire allocated budget on sticks larger than 8 GB.
4. When working on the installation, you must act carefully, since the planks are fragile. You should also be sure to disconnect the PC from the network and carry out all manipulations exclusively with dry hands.
5. The system may have a limit on full memory usage. In this case, even installing the brackets will not help add RAM. It turns out the following: the user added RAM, the computer does not use it. Also, one of the reasons is often a limitation in the motherboard. In addition, the board may not be installed correctly.

If everything is done correctly, then the question is: “How to add RAM to a computer?” will be resolved quickly and without additional complications.

Must be manufactured in a case that already houses the motherboard and processor attached. Something like this:

In the photo above we see that the RAM has already been installed. We also see the installed motherboard and power supply (indicated by an arrow).

In general, it must be said that if you buy a computer case, then, often, it comes already complete with a power supply and does not need to be installed. But in any case, the procedure for installing the power supply into the case is not complicated: you place it in the designated place (usually at the top of the system unit)

and securely fix it with four bolts on the rear wall.

But we won’t connect the power for now, but will install RAM. In the figure below we see how this is done correctly. You need to snap the plastic clips on the connector to the sides, carefully insert the RAM module into the groove that runs through the entire connector and gently but firmly press it downwards perpendicularly until it clicks and fits tightly into the slot. In this case, the plastic clips on the sides will snap into place on their own; if not, look carefully to see if the memory stick is seated as needed and snap them in place yourself.

In the figure, the power connector for the “CPU_FAN” fan is also circled.

Attention! You may damage your computer! Installing RAM is a responsible matter. Therefore, before installing it, it is very important to make sure that you are installing a memory module in the slot that is suitable for its physical characteristics. For example, the DDR2 connector is installed only memory standard DDR2, in DDR3 connectors - only DDR3 form factor memory, etc.

If, when installing RAM, you discover that there is no sticker (special sticker) on it indicating the type of memory, you can navigate purely visually using the “key”. A key is a special “cut” that divides the lower part of the RAM into several parts. Accordingly, each memory slot has a protrusion in the same place. The “key” serves as a kind of protection against attempts to install RAM in a slot that is not suitable for it due to its physical characteristics.

Here's what the two “keys” look like on the old SD-RAM standard:

If you do not want to open the computer, then to determine what type of RAM is installed in it, I recommend using the “CPU-Z” program. It will show what type of components your PC consists of. We analyzed the work of this wonderful utility.

So, we install all the memory chips at our disposal into the slots. On modern motherboards they are often marked different colors(two yellow slots, two red). This is a dual-channel mode for using RAM, which slightly increases its throughput.

To activate the two-channel (or three-channel) mode of RAM, we need to insert the strips in pairs: two identical modules are installed in connectors of the same color, then the other two are installed in connectors of a different color. For getting maximum effect memory chips must be really identical according to their frequency performance characteristics, timings, “CAS” and “RAS” delays. Ideally, they should be purchased from a computer company at one point in time :)

Moreover, the colors of the memory slots do not alternate, for example: yellow, red, yellow, red.

We snap all the clamps, check that all memory modules “sit” evenly in the connectors (memory chips should be on the same height line, without raised edges or “protruding” latches).

This is the simplest way to install RAM. As you can see, everything is simple :)

Users often find themselves faced with the need to increase the amount of RAM when they start working with more demanding software. “RAM” is responsible for temporary storage of data necessary to perform current processor operations. Read more about how to increase RAM in our material.

The amount of RAM determines how easily and quickly the PC copes with work, performing several tasks at the same time.

The procedure for increasing the amount of RAM may involve purchasing additional memory cards or replacing the already installed memory with a larger module. In this case, it is necessary to take into account such characteristics of RAM as type, clock frequency, and, of course, volume.

If you decide to install an additional RAM stick in your PC, it must be of the same type as the one already installed in the device. In addition, you need to find out the maximum amount of RAM that the motherboard and processor supports.

The characteristics of the RAM installed in a PC can be found using special utilities, for example, Speccy or Everest. Or you can remove the cover of your PC case and visual inspection. If only the name of the module is indicated on the RAM stick, then by searching on the Internet you can find all the characteristics you need.

RAM type

Memory differs in speed: newer types of modules can transfer more bits of information at each clock cycle of the memory bus. Also, different memory sticks differ visually.

Modern PCs use DDR2, DDR3 and DDR4 RAM boards. SDRAM and DDR types are older. And when upgrading a PC, it makes sense not to buy an additional bracket of the same type, but should replace it with a module of a newer technology. In terms of money, it will not be much more expensive, but in terms of performance, the advantage will be noticeable.

DDR3 is different from DDR2, for example, reduced energy consumption. There is also a variety of DDR3L modules - with even lower power consumption.

Read the motherboard specifications carefully before purchasing new module RAM, since memory different types will not be able to be inserted into the same slot on the motherboard due to the different location of the cutout on the strips. Thus, SDRAM memory (unlike DDR modules) has two cutouts on the bottom edge of the board and 144 contacts. The DDR module has 184 pins, DDR2 and DDR3 have 240, DDR4 has 288 pins, but the key is shifted from the center to the left edge of the bar.

Frequency and timing

Frequency. This parameter determines the amount of data that can be transferred per certain time, that is, the speed of RAM. The frequency of the RAM must match that supported by the computer's motherboard.

Another important parameter characterizing the speed of RAM is timing. The delay in processing the operation inside the RAM depends on its value. In the name of the RAM module, it can be written as a sequence of four numbers, for example, 9-9-9-24, or CL and a numerical value - the first digit of a 4-digit sequence, that is, CL9 for the example above. The minimum timing value is good for gaming PCs and computers for video editing. For PCs designed for simple everyday tasks, timing has little effect on performance.

RAM slots

Before purchasing an additional RAM board, you need to find out if there is somewhere to put it. And this depends on the number of free slots in your computer.

If your motherboard supports dual-channel RAM, you can use this to improve performance. To do this, you need to purchase not one larger board, but two modules with identical characteristics. Manufacturers often offer such sets (Kits). For example, not one 8 GB module, but two 4 GB modules operating in dual-channel mode. For users who increase memory to play games or use heavy programs, this is important. If the PC is used to work with office software, a browser and to watch movies, then you can safely buy one stick of RAM.

Also today there are motherboards and RAM kits (Kits) that support three-channel operating mode.

What else to consider

When choosing RAM, you also need to take into account the operating system on which you will work, since the minimum amount of required RAM depends on it. Windows 7 and 8 32-bit requires at least 1 GB of RAM, Windows 7 and 8 64-bit requires at least 2 GB (GB), and Windows XP requires at least 64 MB of RAM.

What else should you pay attention to when choosing RAM? To the manufacturer. It is better to choose boards from trusted manufacturers, for example, Corsair, Kingston, Hynix, Transcend, OCZ.

Installation

After you have opened the case of the switched off PC and removed the static charge from your hands, you can begin installing an additional or new RAM module/modules.

1. If you bought a set of two boards to operate in dual-channel mode, check the specifications of the motherboard in which slots they need to be installed.

2. If you are completely changing the RAM, then remove old board memory: open the slot latches on both sides of the module, carefully holding the module by the side edges, and remove it from the slot.

3. Insert the new module into the desired slot, aligning the cutout on the memory board with the protrusion of the connector. Lightly press the module until the clips secure it into place.

4. Repeat the last operation with the remaining memory modules, if any.

5. Close the PC case.
