How to increase the clock speed of an intel processor. So, to overclock the processor using SetFSB, you need

Processor frequency and performance may be higher than specified in standard specifications. Also, over time the system is used, the performance of all main PC components (RAM, CPU, etc.) may gradually decrease. To avoid this, you need to regularly “optimize” your computer.

It is necessary to understand that all manipulations with the central processor (especially overclocking) should be carried out only if you are convinced that it will be able to “survive” them. This may require you to perform system testing.

All manipulations to improve the quality of CPU operation can be divided into two groups:

Optimization. The main emphasis is on the competent distribution of already available core and system resources in order to achieve maximum performance. It is difficult to cause serious damage to the CPU during optimization, but the performance gain is usually not very high.
Overclocking Manipulation directly with the processor itself through special software or BIOS to increase its clock frequency. The performance gain in this case is quite noticeable, but the risk of damaging the processor and other computer components during unsuccessful overclocking also increases.

Finding out if the processor is suitable for overclocking

Before overclocking, be sure to review the characteristics of your processor using a special program (for example). The latter is shareware, with its help you can find out detailed information about all the components of the computer, and paid version even carry out some manipulations with them. Instructions for use:

Method 1: Optimization using CPU Control

To safely optimize your processor, you will need to download CPU Control. This program has a simple interface for ordinary users PC, supports Russian language and is distributed free of charge. The essence this method consists in evenly distributing the load on the processor cores, because on modern multi-core processors, some cores may not participate in the work, resulting in a loss of performance.

Instructions for using this program:

Method 2: Overclocking with ClockGen

- This free program, suitable for accelerating processors of any brand and series (with the exception of some Intel processors, where overclocking is not possible on its own). Before overclocking, make sure that all CPU temperatures are normal. How to use ClockGen:

Method 3: Overclocking the CPU in BIOS

Quite a complex and “dangerous” method, especially for inexperienced users PC. Before overclocking a processor, it is recommended to study its characteristics, first of all, the temperature when operating in normal mode (without heavy loads). To do this, use special utilities or programs (AIDA64 described above is quite suitable for these purposes).

If all parameters are normal, then you can start overclocking. Overclocking for each processor can be different, so below is a universal instruction for performing this operation through the BIOS:

Method 4: OS optimization

This is the most safe method increasing CPU performance by cleaning startup from unnecessary applications and disk defragmentation. Autoload is automatic switching on of a particular program/process when loading the operating system. When too many processes and programs accumulate in this section, then when you turn on the OS and continue working in it, too much pressure may be exerted on the central processor. high load, which will disrupt performance.

Cleaning Startup

Applications can be added to startup automatically, or applications/processes can be added themselves. To avoid the second case, it is recommended to carefully read all the items that are ticked during the installation of this or that software. How to remove existing items from Startup:

Carrying out defragmentation

Disk defragmentation not only increases the speed of programs running on this disk, but also slightly optimizes the processor. This happens because the CPU processes less data because... During defragmentation, the logical structure of volumes is updated and optimized, and file processing is accelerated. Instructions for defragmentation:

Optimizing CPU performance is not as difficult as it seems at first glance. However, if the optimization did not produce any noticeable results, then in this case the central processor will need to be overclocked yourself. In some cases, overclocking does not have to be done through the BIOS. Sometimes the processor manufacturer can provide special program to increase the frequency of a particular model.

When you buy a laptop, based on its price, you expect good performance. And still it is not enough. But you can increase the processing speed central processor(CPU) from the one declared by the manufacturer. Therefore, the question arises: how to overclock the processor on a laptop to get more efficient performance for the same money. There are several affordable and safe options that we will look at in this article.

Let's start with the question "why"

It seems that the laptop is only 3 years old and it has never failed in performing any task (playing a new shooter, watching the latest video rental products, transcoding videos).

But now he can’t cope with half of his needs. What will you have to do - change your laptop? But you can try to “revive” your electronic friend by overclocking the processor. Productivity will increase slightly. If you do everything correctly, the results will please you. In addition to increasing the clock frequency, the memory starts to work faster, and as a result, the speed of applications increases slightly.

But overclocking a laptop processor is half the battle. For everything in this life you have to pay:

Performance will increase, but at the same time energy consumption will increase. This means that battery life will inevitably decrease.
In addition, the laptop will now heat up much more. You'll have to think about the cooling system or, at a minimum, not block the special slots on the bottom and sides.
The lifespan of the CPU will likely be reduced.

Windows also increases productivity

Overclocking the processor in a laptop is a little difficult, but possible. Manufacturers mobile devices, of course, thought about protection and took care in advance to ensure best performance at maximum frequency when it is necessary to speed up work. When the processor is idle, the frequency automatically drops. But you can increase performance without harming your laptop system means by changing the power mode.

To do this in the operating room Windows system There is software tool - « Power supply" You can find it by going to Control Panel. The figure below shows the window that will appear in Windows 7 or 8.1.

You need to go to the section " Power supply" and select the item " High performance».

This is how you can “overclock” a laptop processor without the risk of breaking something. The performance gain will be immediately noticeable.

Overclocking via BIOS

In some models, it is possible to overclock the laptop processor regular means from BIOS. To get into this system, you need to turn on the laptop and press a certain key on the keyboard. A hint about which button to press will be visible for a few seconds on the monitor screen. For example, the inscription shown in the figure below will appear on the hp monitor screen.

After execution this condition The initial menu will appear, which will indicate the key that must be pressed to get into the BIOS.

Let's look at the sequence of actions that need to be performed to overclock the processor:

It is necessary to warn that most often manufacturers lock the CPU to prevent the user from independently changing the clock frequency.

Overclocking using special applications

For relatively old laptops, it is possible to overclock the processor using small program paired with the program Prime95.

Continuing to perform any overclocking method carries the risk of damaging the laptop. All actions must be performed with extreme caution, in small steps.

You need to understand that the maximum you can achieve is a small increase in processor frequency - within 10–15%. A further increase is possible if you prepare the cooling system and change the power supply to the chip. Since during acceleration, along with an increase in frequency, heat generation also increases. By the way, modern processors There is a two-level overheating protection system. If the temperature threshold is exceeded, the processor automatically forcibly reduces the frequency and voltage, which leads to a decrease in heat dissipation. If the temperature does not drop below 95–110º, the laptop either turns off or freezes.

CPU-Z program

Before overclocking, you need data about the chip installed in the laptop. The utility will help with this CPU-Z. This information is necessary for the program.

SetFSB utility

Deliberately designed for quick and easy CPU overclocking. With its support you can safely change the frequency system bus without rebooting the operating system, bypassing the BIOS.

The program has a very easy-to-use interface, and the entire overclocking process occurs step-by-step by moving just ONE slider.

If this laptop supported by the program, chip frequency data will be visible in the lower right corner.

The sequence of actions is extremely simple: increase the bus clock frequency in small steps and test with the program Prime95.

Prime95

A small utility that can measure computer performance. The measurement process is based on performing calculations of Mersenne primes. This action uses all the features of the laptop.

Optionally, you can check both the RAM and the processor itself. While the program is running, you must be prepared for the computer to slow down noticeably.

The frequency is increased in small steps until a freeze occurs. Once the performance data has been saved, Prime95 testing should be stopped and the CPU setup program should be exited.

Conclusion

If everything went well, you can stop there. But this is not the whole complex of work. Performance depends not only on the processor frequency, but also on the memory frequency. It can also be increased by selecting the necessary timings. Advice from friends and searching on the Internet will help you set up your laptop. Overclocking without preliminary preparation It can also cause harm. For game lovers, the next step is to overclock the video card. The main thing is that all actions are thoroughly thought out, and then the efforts will not be in vain.

CPU overclocking | How does a processor become an overclocking legend?

Since the birth of the IBM-compatible PC, certain processors have been positioned as exceptionally suitable products for aggressive overclocking. Some models are famous for their outstanding overclocking potential, while others are famous for their low price. We even remember several unique examples where functions that were initially disabled on the chip could be unlocked.

We decided to take a short excursion into history and compile a list of some of the most interesting ones from the point of view of CPU overclocking.

CPU overclocking | Intel i486

Although overclocking existed before the advent of this chip, this process became much more interesting with the advent of the Intel 80486 thanks to its flexible settings clock speed and the first implemented internal clock multiplier in the i486 DX2 model. Introduced in 1992, DX2 was available in three variants: 40 MHz (20 MHz x2), 50 MHz (25 MHz x2) and 66 MHz (33 MHz x2). Computer enthusiasts could buy a cheaper version of the i486DX2-40 and increase the clock speed to 25-33 MHz using a jumper on the motherboard, resulting in the performance of the flagship i486DX2-66 model.

This may not seem like much today, but such overclocking provided a 60% increase in frequency when computer manufacturers were paying $600 for the 486DX2-66 in batches of 1,000, and the cost of a CPU upgrade kit could exceed $1,000. Purchasing the i486DX2-40 and DX2-50 could save hundreds of dollars, making overclocking a very attractive option for PC enthusiasts.

CPU overclocking | Intel Pentium 166 MMX

Intel released the Pentium MMX in 1997, providing it with an expanded instruction set and twice the large volume L1 cache (a colossal 32 KB at that time) compared to the first generation of Pentium processors. In addition to being noticeably faster than their predecessors, these chips also offered extensive overclocking capabilities. The top-of-the-line Pentium MMX 233 cost about $600 at launch, but the 166 MHz version was $200 cheaper and usually allowed you to reach 233 MHz without much effort. Many of these CPUs were capable of hitting the 250 MHz mark when the FSB was increased to 83 MHz, making the Pentium MMX 166 a top-end processor at a reasonable price.

CPU overclocking | Intel Celeron 300A

Despite its advanced age, the Celeron 300A is still respected in overclocking circles, and it is this chip that is responsible for many people joining the ranks of overclocking enthusiasts in 1998 (including the site's staff). The processor was based on the Mendocino core, designed for low-budget PCs. Intel decided to cut costs by placing the L2 cache directly on the CPU chip instead of using external card with cache, which it produced for top-end Pentium II processors. Although the Celeron had only 128 KB of L2 cache instead of the Pentium II's 512 KB, placing the cache on the chip meant that it ran at the processor's own speed, and in many cases this gave the Celeron 300A an advantage over more expensive CPUs. In addition, the $180 Celeron 300A had incredible overclocking potential: raising the FSB from the factory 66 MHz to 100 MHz allowed it to reach 450 MHz - on par with the $500 Pentium II 450. For the first time in history, overclockers could get the performance of a flagship CPU for less than $200 with minor tuning. It is not surprising that the Celeron 300A is fondly remembered by representatives of the overclocking community, to the emergence of which it was directly related.

CPU overclocking | Pentium III 500E

If Celeron brought a very large number of advanced PC users into the ranks of overclockers, then the Pentium III 500E successfully continued its legacy. This chip, introduced in 2000, was made using a 180 nm lithographic process, was equipped with a 256 KB L2 cache memory and led to a change in the Slot 1 interface to the more modern Socket 370. In contrast to the stripped-down Celeron processors, The Pentium III 500E ($240 at the time of release) was architecturally identical to the Pentium III 750 MHz ($800). Naturally, it provided aggressive overclocking to 750 MHz by simply increasing the FSB to 150 MHz, closely approaching the performance of the rare and expensive ($1000) Pentium III 1 GHz.

CPU overclocking | AMD Athlon and Duron 600 (Thunderbird/Spitfire)

The first generation Athlon was a cartridge that hid a processor board with an installed CPU and cache memory chips. The cartridge was installed in a Slot A slot connector with 242 contacts. Since the cartridge design was completely closed to the user, the multiplier was unlocked using separate device called Gold Finger, with which you could also change the CPU voltage. These processors themselves had excellent overclocking potential, but in 2000 they were replaced by the next generation on the Thunderbird/Spitfire core in the Socket A version, and overclocking by multiplier became easier thanks to the famous L1 bridges. All you had to do was connect four small bridges on the CPU case using a graphite pencil (or better yet, use a special conductive pen) to unlock the multiplier. The Duron 600 for $80 could be overclocked to 1 GHz, which brought it very close in performance to the Athlon 950 ($360). The cost of CPUs that are of interest from an overclocking point of view has dropped below $100.

In addition, more expensive processors The Athlon could be overclocked beyond 1 GHz at a time when Intel's top-end Pentium III models were relatively overpriced, if they could be found at all: Intel processors clocked above 1 GHz were extremely rare for several months after their announcement. After the appearance of Thunderbird's successor - the Athlon processor on the Palomino core - the trick of closing the bridge with a pencil became obsolete, but this happened after Athlon and Duron were able to attract great amount overclockers to your camp.

CPU overclocking | AMD Athlon XP-M 2500+

After AMD blocked the multiplier in the CPU for desktop computers, overclockers realized how great the overclocking potential of the multiplier remained in mobile versions. Costing $25 more than desktop CPUs, Barton's mobile processors offered a lower nominal Vcore (1.45 V) and a custom multiplier. As a result, the Athlon XP-M 2500+, running at 1.83 GHz, could often be overclocked to 2.5 GHz without much effort. Some overclockers were able to reach a frequency of 2.7 GHz when overclocking this processor.

CPU overclocking | Intel Pentium 4 1.6A

First Pentium processor 4 was based on the little-known Willamette core, a design that failed to impress at launch and was even a step back in some performance and power consumption tests. But in 2001, Willamette was replaced by the Northwood architecture, which has double the L2 cache (512 KB) and is based on a thinner 130 nm process technology.

For the first time, computer enthusiasts began to reconsider their opinion about the Pentium 4 precisely at the heyday of Northwood - due to the increased scalability of this architecture. The Pentium 4 1.6A sold for about $300 and was easily overclocked to 2.4 GHz with the factory cooler. This was slightly faster than the flagship Pentium 4 1.8 GHz priced at $560.

CPU overclocking | AMD Opteron 144

While AMD's Athlon 64 processors provided excellent performance, they generally did not have as solid overclocking potential as the Pentium 4. However, in 2005, AMD introduced a 1.8 GHz version of the Opteron 144, priced under $150. Opteron processors have always been server- and workstation-oriented chips that require expensive register memory. However, the Opteron 144 was a version for regular socket 939 single-processor boards that use unbuffered memory. Equally important, it had incredible overclocking potential. Many copies could be overclocked to 3 GHz, while the most powerful Athlon FX-57 models had a frequency of 2.8 GHz and cost $1000.

CPU overclocking | Intel Pentium D 820 and 805

In 2005, Intel's Pentium family was often inferior in performance to AMD's Athlon 64 line. So, the most budget processor Pentium D 820 was priced at $240, which is about a hundred dollars cheaper than the Athlon 64 X2 4200+.

Although the performance of the budget Pentium left much to be desired at factory frequencies, it was a full-fledged dual-core processor, which in capable hands reached a frequency of 3.8 GHz, and some copies even conquered the 4 GHz bar.

In 2006, the Pentium D 805 processor cost $130 was born - the same processor that we overclocked to 4.1 GHz in the article "Overclocking Pentium D 805: dual-core 4.1 GHz processor for $130". The Pentium D was able to shift the attention of enthusiasts to Intel, and this in an era of AMD dominance.

CPU overclocking | Pentium Dual Core/Core 2 Duo E2000/E6000/E8000

Back in 2006, the release of Core 2 Duo processors based on the Conroe architecture allowed Intel to reclaim its crown as the industry leader while ushering in the golden age of overclocking. If we had decided to devote a page to each model in the line that had outstanding scalability, this article would have been at least twice as long.

Let's start with the budget Pentium Dual Core, which was essentially a version of the Core 2 Duo with the L2 cache trimmed to 1 MB. Pentium Dual Core E2140 (1.6 GHz) and E2160 (1.8 GHz) cost $80 and $90 respectively at launch, and easily reached the 3 GHz mark. The Core 2 Duo E6300 (1.866 GHz) cost less than $200 at launch, but could be overclocked to approximately 4 GHz - on par with flagship model Core 2 Duo E6700 (factory frequency 2.667 GHz) for $580.

At a later stage life cycle The Wolfdale Core 2 core, during the production of which a transition was made to a 45-nm process technology, allowed processors like the 3 GHz Core 2 Duo E8400 model to overcome the 4 GHz barrier with minimal resistance. This in no way applies to all Core 2 models, but in our memory there was not a single representative of the line that did not have good opportunities for overclocking.

CPU overclocking | Intel Core 2 Quad Q6600

Core 2 Quad Q6600 was introduced in 2007. But even now, there are enthusiasts who still embrace the capabilities of this quad-core processor, making it something of an anomaly in the fast-paced world of technological advancement.

This CPU, based on the revolutionary Core architecture 2 and 65 nm technical process and having a factory frequency of 2.4 GHz, easily reaches the middle of the 3 GHz frequency range. At the time, this was surprising given the complex architecture of the quad-core CPU.

Although the Q6600 was priced at $850 at launch, by 2010 it had dropped to $200, making this processor popular with computer enthusiasts on a budget. In 2011, the Q6600 was replaced by the Core 2 Quad Q9550, another CPU with an excellent reputation among overclockers.

CPU overclocking | Intel Core i7-920

Intel's Nehalem architecture was introduced in 2008 along with the Core i7 brand. Quad-core Core 2 Quad processors have performed well, but rethinking the Hyper-Threading feature allows the Core i7 to take a step forward in the types of workloads associated with parallel computing. In addition, the LGA 1366 platform is equipped with a three-channel memory subsystem, and the memory controller is implemented directly in the processor itself.

Flagship model Core i7-965 Extreme(3.2 GHz) sold for $1000 and had an open multiplier. But the $285 Core i7-920 (2.67 GHz) offered identical architecture for less than a third of that price. Although it had a locked multiplier, it was possible to increase the frequency to 4 GHz through BCLK overclocking. In fact, the Core i7-920 is still quite powerful and provides stable performance after overclocking, which speaks to the long life of the Nehalem architecture and the X58 Express platform.

CPU overclocking | AMD Phenom II X2 550 and X3 720 Black Edition

The flagship model Phenom II from AMD has never shone with overclocking potential (overclocking efficiency did not reach 4 GHz). But the processors of the Black Edition line, according to at least, made configuration easier thanks to an open multiplier. The Phenom II X2 550 and X3 720 had their own unique features, namely in some cases they allowed you to unlock additional cores if the motherboard you were using supported such a function.

While some of these processors did have defective cores that could not be revived (making overclocking a gamble), many were capable of operating as quad-core processors, sometimes at speeds in excess of 3 GHz. In 2010, when top-end quad-core Phenom IIs cost $180, you could take a risk, and as a result, often become the owner of a processor more than high class, having spent $100. In the worst case, for relatively little money you became the owner of a dual-core or triple-core CPU, which could still be easily overclocked thanks to an open multiplier.

CPU overclocking | Intel Core i5-2500K

Intel presented its chips based on the architecture Sandy Bridge in 2011, and they were based on the 32nm process technology. Compared to top Core i7 models, Core processors i5 lacked a 3 MB shared L3 cache and Hyper-Threading function. None of these measures resulted in a significant difference in performance, with the exception of load scenarios with high degree parallelism.

On the other hand, the Core i5-2500K includes an unlocked multiplier, making it possible to overclock the CPU from the factory frequency of 3.3 GHz all the way to 4.5 GHz using air cooling. We think the $225 price tag is reasonable given the high performance potential of this chip. Even today, the architectures' relatively meager advantages are what make the 2500K a worthy choice for computer enthusiasts.

The desire for your computer to work on high speeds familiar to every user. Some people need this for a comfortable time in games, while others need it for work, so that several applications can be successfully opened at once.

With a professional approach to overclocking a computer, its performance can increase to a tenth or even a fifth of the whole.

It is worth knowing that overclocking the processor does not always have a significant effect. If the RAM takes up 1GB, then increasing it by one more unit will give the desired result, and if you have powerful computer, then the processor gain may not be noticeable.

In any case, you can only find out whether your actions with the processor worked experimentally.

Warning!

However, you should not get too carried away in regulating the processor. This may cause it to break. Here are a few steps to help it stay in working order:

Study this topic. Special literature or forums with websites that will tell you what to do will help you with this. It's also worth looking at the specs of your processor. It may turn out that he is not capable of squeezing high speeds.
If you increase it, then only the processor frequency. There is no point in regulating the core power supply by changing the voltage.
Divide the increase in purity into several stages, let each be 100 MHz.
After each lifting step, test the system for stability and temperature performance. You should constantly monitor the temperature while you are working with the processor. When the maximum purity limit is exceeded, the computer will reset it to its initial characteristics. The higher the frequency, the higher the temperature. If it is reduced, the CPU crystal may break, and then it will have to be replaced.
If the user nevertheless decides to change the voltage, then this should be done carefully and carefully monitor the characteristics of the computer. Typically, this figure is increased in small steps of 0.05 - 0.10 V. However, exceeding the threshold of 0.30 V can lead to equipment failure.
Since the CPU is a fragile thing, you should stop any attempts to strengthen it after the first failures. It is necessary to leave it at the frequency at which it worked successfully, and not repeat attempts to improve it. There are cases when the processor frequency has increased and it works successfully, but it is always warm and does not have time to cool down. In this case, it is worth changing the cooling system.
The only thing you shouldn't overclock is laptops. Their cooling system is not designed to improve performance. But if you still decide to do this, then you should change the cooling equipment to a more powerful one.

Programs for monitoring device status

CPU-Z

— A common utility that will show the user voltage, frequency and other indicators that characterize computer performance

Prime95

Publicly available benchmarking software. Performs stress testing on the computer when the frequency increases. Capable of performing lengthy checks to obtain large quantity data

LinX

Similar to the program above. One of the differences is support for the Russian language. It fully loads the processor and tests it. The user may feel like their device is frozen

CoreTemp

Another free program. Shows the temperature of the chip in the processor in real time. In addition, it often shows the FSB bus along with the multiplier.

The first point on choosing programs for successful overclocking of the system has been completed.

The list includes applications for benchmarking, stress testing, and chip temperature information.

Before starting work, you should check your computer for stress using basic programs. They will calculate the initial characteristics and help in detecting various problems.

The next step is to check and study the characteristics associated with motherboard and processor. The data and potential of both may be different, so it's worth checking them out.

Also Special attention should be applied to the multiplier. If it is closed for change, then you will not be able to overclock your processor.

To start it, you need to hold down one of the following keys in the first seconds when you turn on the computer, when the POST screen appears: F10, F2, F12, Esc - various computers The buttons to open this application are different from each other.

It is through this basic program and the device will be overclocked.

There are old and new BIOSes. They differ little from each other in terms of production, but they may have a different interface.

These programs are divided into two types:

AMI or Phoenix AWARD

The first tab is called Advanced, it can also be called JumperFree Configuration or AT Overclock.

The second one is called Frequency, Voltage Control, it can also be called as follows: overclock.

After performing these manipulations, you should open the advanced mode and select the following in it: AI Tweaker or, if the first does not happen, then Extreme Tweaker.

As a result of these actions, a window will appear in which you will need to increase the frequency.

First of all, you need to reduce the memory bus speed. Following these instructions will help you avoid memory errors. It's called Memory Multiplier or Frequency DDR. Worth installing minimum value, which will be indicated there.

Then you should increase the fundamental frequency by a tenth of a hundred. This value is approximately 100 MHz.

It is hidden under another name - FSB bus. Its speed is the internal basis of your processor.

Basically, it is equal to a value of 100 MHz or more, which is multiplied by a certain multiplier indicated in the status information.

That is, if the initial power is 200 MHz, and the multiplier is 10, then the computer frequency will be 2 GHz.

Most computers can easily handle a 10% increase, meaning the frequency will now be 2.2 GHz.

However, if you encounter problems with stability or temperature, you should stop all attempts and reduce the settings to the default option.

A temperature of 85 degrees will be critical for any computer, and its processor will break down.

If successful, continue performing the stat upgrade. The stress test should be run after each increase in frequency.

Increasing processor power through multipliers

This option applies if your multiplier readings are unlocked. This is an easier option to set up.

You should reset first basic setup frequencies. Canceling it will help you adjust the frequency better.

When using a low base frequency with a large multiplier, operation stability is increased. A high frequency and a small multiplier gives excellent performance. In this case, you should look for a value at which stability and productivity will be equally strong.

After resetting the settings to default, you should start raising the multiplier. It is worth doing this in small increments of half a unit. The multiplier itself is hidden under the name CPU Ratio or CPU Multiplier.

Once lifted, run the temperature check and stress test process.

Then start increasing the multiplier again until the first problems with stability begin. If this is not enough for you, then you can start increasing the voltage.

Increasing it will make it possible to increase the multipliers by a few more points.

The following short article will help the reader on how to increase tension.

Increasing the voltage to power the core

You can increase the voltage using normal adjustment. Entitled CPU Voltage or VCore our voltage indicator is hidden.

If you nevertheless decide to increase it, then you should do this as carefully as possible.

If you randomly increase the voltage, it can go beyond safe limits. And this will ultimately damage not only the processor, but also the motherboard.

It is worth increasing in steps equal to 0.025 or any other minimum value.

However, do not exceed the 0.3 V limit.

This could end badly for the components of your device.

You should also perform a stress test after each lift.

With the last overclock you left the system in an unstable state, so after raising it it will begin to come to its senses.

If the system has already achieved stability, then you should monitor the temperature. It must not be high.

If the system continues to remain unstable, then it is necessary to reduce the multiplier or the base clock purity.

Your system will eventually stabilize. After that, you can go to raise the multiplier or frequency.

In this matter, you pursue one single goal - to achieve stable operation and high performance with minimal voltage consumption.

Repeat all this work until you reach maximum value temperature or voltage. Eventually you will come to this conclusion: you will no longer be able to increase productivity. This will be the limit of your processor's components that you will not be able to go beyond. Only if you change the components, for example, the motherboard.

6009

Overclocking is a forced increase in the processor clock frequency above the nominal one. Let us immediately explain what these concepts mean.

A clock cycle is a conditional, very short time period during which the processor executes a certain number of instructions program code.

And the clock frequency is the number of clock cycles in 1 second.

Increasing the clock frequency is directly proportional to the speed of program execution, that is, it works faster than an unoverclocked one.

In short, overclocking allows you to extend the “active life” of the processor when its standard performance no longer meets the user’s requirements.

It allows you to increase the speed of your computer without spending money on buying new equipment.

Important! The negative aspects of overclocking are an increase in computer power consumption, sometimes quite noticeable, an increase in heat generation and accelerated wear of devices due to operation in abnormal mode. You should also know that when you overclock the processor, you also overclock the RAM.

What should you do before overclocking?

Each processor has its own overclocking potential - a clock frequency limit, exceeding which leads to inoperability of the device.

Most processors such as intel core i3, i5, i7 can be safely overclocked to only 5-15% of the original level, and some even less.

The desire to squeeze the maximum possible clock frequency does not always pay off, since when a certain heating threshold is reached, the processor begins to skip clock cycles in order to lower the temperature.

It follows from this that for stable operation of an overclocked system, good cooling is necessary.

In addition, given the increased power consumption, it may be necessary to replace the power supply with a more powerful one.

Immediately before overclocking, you need to do three things:

Upgrade your computer to latest version.
Make sure that the installation is in good working order and reliable.
Find out the original clock speed of your processor (look in the BIOS or through special utilities eg CPU-Z).

Also useful before overclocking test the processor for stability at maximum load. For example, using the S&M utility.

After this, it’s time to begin the “sacrament.”

SetFSB is an easy-to-use utility that allows you to overclock the processor on the fly by simply moving the slider.

After making changes, it does not require restarting the computer.

The program is suitable for overclocking both older processor models like Intel Core 2 duo and modern ones.

However, it does not support all motherboards, and this is an absolute necessity, since overclocking is carried out by increasing the reference frequency of the system bus.

That is, it affects the clock generator (PLL chip or, as it is called, a clocker) located on the motherboard.

You can find out whether your board is included in the list of supported ones on the program website.

Advice! To avoid processor failure, working with SetFSB is recommended only for experienced users who understand what they are doing and know about possible consequences. In addition, an untrained user is unlikely to be able to correctly determine the model of his clock generator, which must be specified manually.

So, to overclock the processor using SetFSB, you need:

Select from the “Clock Generator” list the model of the clocker installed on your motherboard.
Click the “Get FSB” button. After this, the SetFSB window will display the current frequency of the system bus (FSB) and processor.
Carefully move the slider in the center of the window in small steps. After each slider movement, it is necessary to monitor the processor temperature. For example, using the Core Temp program.
Having selected the optimal position of the slider, you need to press the Set FSB button.

The advantage (and for some, the disadvantage) of the SetFSB utility is that the settings made in it will only be valid until the computer is rebooted. After restarting, they will have to be installed again.

If you don’t want to do this every time, the utility can be placed in startup.

CPUFSB

CPUFSB is the next program in our review for overclocking Intel core i5, i7 and other processors, which can be downloaded from the developer’s website.

If you are familiar with the CPUCool utility - comprehensive tools monitoring and overclocking of the processor, then know that CPUFSB is a dedicated overclocking module.

Supports many motherboards on Intel chipsets, VIA, AMD, ALI and SIS.

Unlike SetFSB, CPUFSB has a Russian translation, so it is much easier to understand how to handle it.

The principle of operation of these two programs is the same: increasing the reference frequency of the system bus.

Operating procedure:

Select the manufacturer and type of your motherboard from the list.
Select the brand and model of the PLL (clock oscillator) chip.
Click "Take frequency" to display in the program current frequency system bus and processor.
It is also necessary to increase the frequency in small steps, while controlling the processor temperature. After selection optimal settings Click "Set Frequency".

CPUFSB allows you to set the FSB bus frequency the next time you start the program and when you exit. The current settings are also saved until the computer is restarted.
