With which you can increase processor performance. Using operating system settings optimizer programs

If you have several processors or one multi-core processor in your computer, then you can optimize its operation using the program CPU Control. Despite the fact that multiprocessor computers and multi-core processors are no longer uncommon, most programs are still not designed to fully work with them. And therefore such devices cannot show their full potential. It can be fixed.

The CPU Control program (can be downloaded from the link at the bottom of the article) can distribute running processes across certain processor cores. For example, everyone background processes(antivirus, device drivers) should be placed to run in one core. Programs that are often used (browsers, browsers, instant messengers) - second. System processes- in the third. And heavy programs (games, for example) in the fourth or allow them to use all cores.

Besides what does CPU program Control, you can also configure the system startup by distributing this process to all cores. I wrote about this.

Using the CPU Control program, you can give any distribution to processes. And the more cores or processors you have at your disposal, the more choices you have. However, it is impossible to say which processes should be optimized, since it depends on operating system, existing processes, the processor itself. Therefore, this issue is resolved individually and experimentally. CPU Control allows you to easily and safely experiment with the operation of the processor.

After you download the CPU Control program, install it and run it. Before you start optimizing, click on the “Settings” button (bottom right) and select desired language interface, check the box next to “Autostart with Windows” and “Minimize”. If your computer has 4 cores, check the appropriate box. And click “Close” in this window.

Setting up the CPU Control program

After this, you must select the operating mode in the CPU Control program.

• “Auto” mode - allows you to distribute processes in kernels automatically. Perhaps this the best option for those who do not want to delve into the details of optimization. You can also select 9 profiles, which differ in their (unknown) principles of process distribution, and among them you can choose the best one for your computer experimentally.
• Manual mode - for more fine tuning optimization. Requires some knowledge of the operating system. Not recommended for inexperienced users. To assign a process to a specific kernel, you need to click on it in the list right click mouse and select the desired core(s) - for example, CPU 1 or CPU 1+2.

Manual distribution of processes among cores through the CPU Control program

• The “CPU 1” and “CPU 2” modes allow you to distribute running processes into only one core. And it’s not entirely clear why this is needed, since this will slow down the computer’s operation.
• Off mode turns off the program.

If it is not clear from what has been described how to work with the CPU Control program, then watch the video below.

If you are using this program in automatic mode, and do not notice a performance increase, then you should configure it in manual mode. The CPU Control program is far from perfect, and this is especially true for its “Auto” mode. Sometimes it can even slow down your computer. But practice shows that with the help of experiments and the wonderful “poke” method, everything can be adjusted. Moreover, the CPU Control program provides a huge testing ground for experiments.

Clock frequency is the number of oscillations that occur in one second. The number of synchronizing cycles, if we talk about a personal computer, is operations (instructions program code) that the processor executes during this period of time. From clock frequency The performance of the PC directly depends and it can be overclocked by increasing the number of oscillations.

« Hertz" - this is the name of the unit with which frequency is measured. This unit of measurement was developed by Heinrich R. Hertz. At the end of the 19th century, a physicist conducted a special experiment that proved the wave nature of light. According to Hertz's theory, light is nothing more than electromagnetic wave, propagated by special waves. And the longer electromagnetic radiation(wave), the brighter the light we see. The color of light directly depends on the wavelength.

There are two types of clock frequency - external and internal. The board, processor, and RAM exchange information (data), and the external frequency is responsible for this. But it depends on the internal one how quickly and correctly the processor itself will work.

If you overclock the processor, all programs (operations) will run much faster than if this is not done. Overclocking is used when the user is no longer satisfied with the performance of his computer and wants to increase standard number synchronizing cycles. What does this procedure give to the user? The opportunity not to spend money on a new processor and continue working with the old one, which after overclocking can still last longer time. Your computer will become more productive without replacing hardware, and that’s a fact.

Once you overclock your processor, you will encounter some problems, quite significant ones. After completing the procedure, your personal computer will begin to consume more electricity, in some cases the increase is very noticeable. Overclocked processors suffer from increased heat dissipation. And most importantly, devices break down faster, because they have to work in extraordinary mode. Along with an overclocked processor, the number of oscillations (clock frequency) of the RAM also increases, therefore, it can also quickly fail.

What should you do before overclocking?

Overclocking reserve is the maximum clock frequency. If this maximum is exceeded, the device will fail. Almost all processors are overclocked without consequences up to 17% higher than the original data. And there are devices that can be overclocked for even less. Intel has a special series of processors that have an unlocked multiplier (it is possible to change it in the BIOS). These devices are the ones that overclock best.

Maximum clock speed is bad. On the one hand, a personal computer increases its performance significantly, and on the other hand, when the processor heats up to its maximum permissible value, it reduces the temperature by skipping oscillations (cycle). Therefore, if you want to overclock the device to the maximum, then you must take care of a good cooling system. Without cooling, you will not get the maximum percentage by which you overclocked the processor. It will decrease due to the fact that it will skip cycles, trying to lower the temperature. Also, do not forget that electricity consumption also increases. In order for an overclocked processor to work efficiently, you need to install new block nutrition.

Before overclocking your processor, follow these three steps:

1. The computer's BIOS must be updated to latest version.
2. You should know how the processor cooling system works: whether it is installed securely and whether there are any malfunctions.
3. Determine the processor clock frequency and its initial value by looking in the BIOS, or using special programs.

You can use, for example, RMClock Utility or . With these free utilities you can conduct benchmark tests and measure the maximum clock speed of the device. Both programs are free and can be downloaded from official websites.

Also, check how your processor performs under extreme load. To carry out tests, you can use the program. This free, easy-to-use but functional utility will check the stability of your device and display the results on the screen.

Only after this you can start overclocking the processor. Below we will look at three programs that can be used to do this safely.

Review of programs for overclocking Intel processors

SetFSB

Using the first program is very simple, and even inexperienced users can master it. True, the developers do not recommend it to beginners in order to avoid critical errors. This utility will very quickly and easily overclock CPU without rebooting the system. One slider movement specialized utility and everything is ready.

With this specialized program You can overclock any processor model, but only if the motherboard is suitable. Not all models are supported by it. And when overclocking the processor, the motherboard has great importance. After all, during the procedure, the system clock frequency also increases. And this leads to an impact on the clock generator, which is located on the motherboard.

Before using this utility, go to the official page and check if there is a model for yours in the list of approved motherboards. personal computer. The advantages of this program include its light weight (only about 300 kb), ease of learning and management, high operating efficiency, and regular updates.

Recommendation! The developers of the program do not recommend using it for beginners who do not understand the dangers it may pose. And besides, an inexperienced user is unlikely to be able to independently find out what model of clock pulse generator is in his computer. It is specified manually.

Overclocking the processor using the SetFSB utility:

• What model of clock generator is on the motherboard? Select it from the "Clock Generator" drop-down list.
• Click "Get FSB". You will see two frequencies - the device itself and system bus.
• Move the slider carefully, constantly measuring the processor temperature. This can be done using a specialized utility.
• When the slider position is optimal, click Set FSB.

The most interesting thing is that the settings are valid as long as the computer is running. The next time you start, you must set the frequency again. The developers recommend that experienced users run the program not independently, but from startup.

CPUFSB

Another one effective program, allowing you to overclock all models of Intel processors. The utility is not free and can be downloaded from the official developer page. The program is included in a specialized tool that allows you to overclock the processor and monitor its stability. If you couldn't use the first program, SetFSB, because it didn't support your motherboard, then this one might work. Since more motherboards are supported here.

In addition, it is more convenient here user interface: there is support for the Russian language. As for overclocking itself, these two programs work the same way: they increase the system clock frequency.

How to overclock a processor using CPUFSB:

• Find your model in the drop-down list motherboard.
• Find the PLL chip model in the drop-down list.
• Click on “Take frequency”. You will see the initial frequency of the device and system bus.
• The frequency increases in the same way: with careful movements until the required level is reached. Do not forget to monitor the processor temperature using a special program. As soon as they are installed required values, click “Set frequency”.

Settings similar to the first program are valid only for the duration of operation. Turning off the computer cancels all configured settings.

SoftFSB

The program also allows you to quickly and easily overclock the processor, has a simple user interface and is easy to learn, although English language. The only negative is that it is no longer supported by the developer, and therefore it is not clear whether you will be able to use it. The utility can be downloaded on the official page for free. With this program you will overclock a processor with any model of motherboard and clock generator.

This program is also intended only for experienced users who understand motherboard models and clock generators.

How to overclock a processor using SoftFSB:

• Find your clock generator and motherboard model.
• Find out which one this moment bus and processor frequency.
• Gently move the slider until you find the desired frequency. At the same time, do not forget, as in similar programs, to monitor the processor temperature.
• When the optimal number of clock cycles is selected, click on “SET FSB”.

This is how three work universal utilities. If you are afraid to use them, download programs from motherboard manufacturers. They are safe to use and suitable for inexperienced users who are afraid of harming the computer with their actions.

These utilities, which you met above, can be used for both personal and laptop computers. But when overclocking the processor to laptop computers You should be as careful as possible so as not to harm or damage the processor. The system clock speed should not be increased to the maximum value.

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 program code instructions.

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! Negative sides Overclocking is 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 a processor, you also overclock it. 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 overclocked system is necessary good cooling.

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:

• Update your computer to the 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.”

Review of programs for overclocking Intel processors

SetFSB

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 with using SetFSB, need to:

• 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 processors Intel core i5, i7 and others, 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.

My friend the computer
April, 2014

Modern processors able to regulate their productivity depending on the tasks performed. If desired, dynamic changes in clock frequency can be optimized, and for older processors, a corresponding feature can be added.

A processor is installed on the test bench AMD Phenom II X6. But most of the time he works on low, economical frequency 800 MHz - no faster than a twelve-year-old Pentium III. Under load, all six cores quadruple this figure - up to 3.2 GHz. All representatives of new generations of CPUs increase their efficiency and performance thanks to this dynamic adjustment of clock speed. We'll cover how this technology works and how it can be optimized to improve laptop battery life or PC performance, as well as how to enable it in older processors.

Today, desktop computers and laptops work more efficiently thanks to a flexible system of processor activity modes. Initially, this principle was used in laptops. Beginning with Pentium processor III for mobile platforms, Intel introduced energy saving technology SpeedStep, which in battery mode reduced the processor clock speed in order to provide longer battery life by reducing performance.

SpeedStep: Battery Saver

Since 2003, when the Pentium M was introduced, laptops have gone to great lengths to make efficient use of battery power and deliver sufficient performance when needed. They analyze the processor load and provide their full potential only when it is really necessary. This allows you to be more careful with the battery and makes the cooling system work noticeably quieter.

Since the main goal of laptop manufacturers is to reduce power consumption and increase the efficiency of the cooling system, mobile computers leave almost no room for overclocking. Therefore, there are fewer BIOS settings available on a laptop than on a desktop PC. Tuning programs from manufacturers are also rare. However, there are safe ways Optimizing dynamic clock speed - using power plans in the Panel Windows management. The need for such actions arises if, for example, after a few minutes of processor operation under high load The laptop's performance suddenly drops and HD video starts to slow down.

Another reason may be the constant switching of fan operating modes. This means that the processor, under full load, forces the fan to work at its limit, which is not enough to fully cool the CPU in this mode. As a result, the latter overheats, despite the rotation of the fan with maximum speed. As a result, the processor reduces the clock frequency, after which its temperature and fan noise decrease. When it cools down enough, it increases the frequency again, and everything repeats all over again. In this case, limiting the maximum processor performance using the Windows power plan will help.

Power Plan: Safe Optimization

To eliminate fluctuations in laptop performance, go to the "Power Options" section in the Windows 7 Control Panel. Here you can select one of the power plans - it is best to choose "Balanced" as the starting point for the settings.

Check it and click on the link “Set up power plan”, and then on “Change Extra options nutrition." Expand the “Processor power management” item in the list, and then the “Maximum processor state” sub-item. There are two parameters here - “On mains” and “On battery” - with the default value set to 100%. Now we need to find out at what value the processor maintains the required performance without overheating. At 95 or 90%, laptops often run more consistently under full load and don't take longer to complete long-running computing tasks due to the lack of power surges. If your most important concern is battery life and low level fan noise, set the battery setting to an even lower setting.

Changing the parameters in power plans is not dangerous, as they are within the boundaries provided by the manufacturer. Of course, you should avoid the anti-power saving "High Performance" plan, which is only useful for benchmarks. It maintains the processor's rated performance constant, which increases power consumption and fan noise, thereby shortening the life of the computer. This applies not only to mobile phones, but also desktop computers, which allow more extensive intervention in controlling the processor clock speed.

Desktop: floating clock speed

Desktop PCs also adjust their clock speeds to suit the needs of the day. In this case, the main attention is directed to optimal use processor and to improve performance. This Intel technology called Turbo Boost and appeared in Core processors i5 and P. At first it was only about solving the problem that many programs could not fully use the capabilities multi-core processors. As a result, one core was loaded at 100%, and the rest were inactive. Processors with Turbo Boost support use free potential to overclock a loaded core above the rated clock speed. The latest Sandy Bridge-based processors, which appeared earlier this year, have gone one step further: they can overclock all processor cores for a short time, which would lead to failure if used for a long time due to overheating.

But since the interval during which the processor and radiator heat up is known, the first of them, not reaching the overheating limit, begins to gradually reduce the clock frequency to a given level, so that the temperature curve stops at the upper limit of the permissible value. Thus, the processor can provide noticeably higher performance for up to 25 seconds - this is enough to, for example, perform bootstrap, run a program, or speed up operations in Photoshop. AMD offers a similar technology called Turbo Core in its the latest processors Phenom II, which have the letter T in their markings.

BIOS setup: dealing with frequency and voltage

Achieving both goals of dynamically changing processor settings (increasing performance as needed and reducing power consumption as possible) depends on two parameters - clock speed and processor supply voltage. It is important to understand their interdependence before making changes that are outside the manufacturer's specifications and will void your warranty.

The clock frequency determines how many times per second the transistors switch, that is, how many computational operations per second the processor can process. To improve its performance, it is necessary to raise the clock frequency above the nominal value so that it can perform more operations in the same time. However, due to manufacturing features, not all transistors in the processor (and there are millions of them) can support the same speed. This leads to errors in calculations, instability and system failures.

The solution is to increase the processor supply voltage, which allows you to stabilize the system due to the fact that with it all transistors can switch faster. But this simultaneously causes a rise in temperature, which can lead to an emergency shutdown. Moreover, when too high temperature sensitive transistors may fail or fail. Therefore, the limits for increasing the processor supply voltage are very narrow.

To save energy, it is first necessary to reduce the chip's supply voltage, since its energy consumption is a quadratic function of this indicator. This means that with a 20% reduction in voltage, power consumption will decrease by 36%. In this case, problems again arise due to the uneven sensitivity of the transistors: when the voltage is reduced, some of them stop switching or do not do so quickly enough. This rarely causes system failures, but there may be calculation errors that may appear as unstable work PC, damaged files and incorrect calculation results. Therefore, after changing the supply voltage or processor clock frequency, it is recommended to run the Prime95 program and let it run for at least six hours in stress test mode (Options | Torture Test). If the program does not generate error messages, the system will work reliably for a long time. You can change the clock frequency and supply voltage of the processor through the BIOS or using software tools from the motherboard manufacturer.

Overclocking: Maximum CPU Performance

You can enter the BIOS immediately after turning on the computer by pressing the Del or F2 key, depending on the manufacturer of the motherboard or laptop. Refer to the user manual for information about setting parameters for your processor. On our test computer with motherboard ASUS M4A89GTD they are located on the BIOS Al Tweaker tab. Most settings are set to Auto by default. Before manual installation clock speed, Turbo Boost or Turbo Core must be disabled. Instead of the desired processor frequency value, you should enter two parameters - the clock frequency of the system bus, which is the basis for synchronizing the entire system, and the processor multiplier. This multiplier indicates how much faster the chip is relative to the system bus speed. The last setting on our test PC is 200 MHz, and the multiplier Phenom processor IIХ61090Т-16. This corresponds to a clock frequency of 3200 MHz. The system bus clock speed and processor multiplier for your computer can be found in the CPU | Clocks of the CPU-Z program.

Overclocking steps depend on whether your computer can freely change the processor multiplier value. This is quite rare - for example, with CPUs for overclockers, which Intel can recognize by the letter k at the end of the marking, for example Core i5 2500k. AMD adds the Black Edition mark to the name of such processors. Gradually increasing the multiplier value, test using Torture Test from Prime95 how stable and error-free the system works. If errors or failures occur, carefully increase the supply voltage and repeat the test.

It's more difficult when you can't set the multiplier higher than the preset value, which is the case with most processors. Then it remains the only way out- increase the clock frequency of the system bus. A small increase, like on our test PC (from 200 to 210 MHz), does not cause problems in most cases. If you raise the FSB speed much higher, you will have to worry about overclocking the RAM. To do this, you need to set its frequency manually. For some models, this is achieved by increasing the memory divider in the BIOS. Special programs for Windows OS allow you to configure the processor during operation for higher performance or lower energy consumption. This is most conveniently done using configuration programs from motherboard manufacturers. For example, ASUS supplies the TurboV Evo overclocking utility in the Al Suite package, which will give you the ability to change the above parameters. If you find values ​​that provide the desired result, they can be saved as profiles and activated as needed - for example, one profile to save energy and another to improve performance. If your motherboard or laptop manufacturer does not provide tuning software, and your processor is relatively old, use the RightMark CPU Clock Utility or CrystalCPUID software tools to change the clock speed or voltage of the processor - to increase performance or reduce power consumption.

Graphics card: performance or efficiency?

By dynamically adjusting the GPU clock frequency, you can achieve good results in terms of increasing the efficiency of the entire system, because their power consumption is comparable to the CPU.

For example, GeForce video card NVIDIA's GTX 590 consumes over 400 watts in modern games like Crysis, which is 2.5 times more than an entire six-core PC under full load. When dissipating heat, its fans make a terrible noise with a volume of more than 8 sones. All the more important is that in 2D mode the noise level and energy consumption are significantly reduced. The card significantly reduces the clock frequency GPU, power consumption drops to 55 W, although the fan noise at 3 sones remains quite loud. Since less powerful video cards with increased load become quite noisy, almost all models use dynamic adjustment of power and energy consumption, which is performed automatically, like processors.

Adjusting the CPU clock speed

Similar to the CPU, it is possible to increase or decrease the clock frequency of graphics chips within the limits provided by the manufacturer. There is an OverDrive item in the AMD video card driver menu. By activating this feature, you can change the clock speed of the GPU and memory of the card - raise it to improve performance and lower it to reduce power consumption. The cooling system can also be controlled here. To change the clock speed on graphics cards NVIDIA cards, in addition to updating the driver, you will need to download system tools from the video chip manufacturer.

Laptop: Disabling GPU

More effective method than reducing the clock frequency graphics card, - it is her complete shutdown. Laptops supporting Optimus technology from NVIDIA or PowerXpress technology from AMD contain both powerful discrete and economical built-in video adapters. Most of the time, the integrated chip works, and when it is necessary to solve more serious problems, the discrete one comes into play.

All modern computers- These are multi-core devices that affect system performance. However, Windows 7, like any other operating system, does not use the processor cores to their full capacity. This is due to saving resources on the PC itself. Therefore, if your programs do not slow down and errors do not occur, we do not recommend using all the cores of the graphics accelerator. This action should be performed in cases where the PC power is not enough to run standard programs and games.

Configuring kernels through the startup menu

This option for using all the processor power is the simplest and safest. It is suitable for all versions of Windows OS (except XP). Any user, even a beginner, can perform these steps.

• Press “Win+R” and enter “msconfig”.

• The System Configuration window will open. Go to the “Download” tab and click “Advanced options”.

• In the window that appears, check the “Number of processors” box so that the item with the choice of cores becomes active. We set the maximum memory.

• Afterwards we save the result and reboot the system. Multitasking mode will turn on.

IMPORTANT! If your PC turns off during advanced settings, check whether your power supply has enough power.

Advanced CPU settings with AIDA64

AIDA64 is useful not only for its status and performance reports individual components PC, but also with functions for unlocking processor cores. To use the CPU capabilities using this program, you should do the following:

• Launch the program and select “ Motherboard", "CPU".

• Next, turn on each of the cores and reboot the system.

If the involved kernels did not bring benefits, it is worth returning the settings back.

Using CPU Cores Using CPU-Z

The CPU-Z program allows you not only to check what characteristics a particular PC component has, but also to optimize the operation of some of them. In order to enable all kernels, you must do the following:

• Let's launch the program. Go to the “CPU” tab.
• In the “Theads” item you need to set the value the same as in “Cores”.

• After rebooting the system, you need to check the changed settings.

Overclocking the processor using BIOS settings

To use all the cores of the graphics accelerator, you should go to the BIOS. To do this, restart your PC and press “F2” or “Del” several times. Then you need to make the following settings:

• Find the “Clock Calibration” section (It is only available for AMD products). Set the value to “All Cores”. In the “Value” item we set the value as a percentage.

• After rebooting the system, it is worth checking the PC for functionality.

These methods are quite simple and in rare cases cause the system to crash. However, if after editing the settings errors begin to appear, you should stop unlocking the cores and return the settings back.
