Download a program to overclock an intel processor. Programs for overclocking an Intel processor

Avid gamers, people who work with bulky media, and those who require complex computing processes often find their hardware underpowered. And if they don’t want to spend money on upgrading equipment, or there is no need for a dramatic increase in performance, then overclocking or overclocking the processor, video card or RAM.

Overclocking or overclocking – increasing the performance of components personal computer software or physical manipulation.

All devices operate at 50-80% of maximum power in normal mode. Restrictions are imposed by manufacturers and are designed to extend the life of the device. There are several ways to remove or bypass these restrictions. True, this will significantly increase the load and, consequently, reduce the service life of the device.

Thus, by taking the right actions, you can increase the performance of your processor, video card or RAM by 20-50%. Achieving the highest possible productivity is quite difficult - this is already an area professional activity. But 20-30% growth can be obtained without delving into the constructive jungle.

IMPORTANT: Overclocking the processor on a laptop is an extremely risky step and it is strictly not recommended to take it; a weak cooling system will not prevent the consequences of rising temperatures. Therefore, you need to think carefully before overclocking your laptop processor.

The following will provide tips on how to properly overclock your processor. It is difficult to damage your computer on motherboards with built-in overclocking utilities. Special software fuses, when detecting an excess of normal temperature, reset the settings to their original state.

Despite all precautions, it is better to play it safe and provide additional cooling before overclocking the processor.

Proper processor overclocking

For effective magnification clock frequency processor, there are two ways: correcting BIOS settings and special software. Both methods are relatively safe and accessible to users with modest knowledge of computer technology.

IMPORTANT: Before increasing processor performance, it is better to think carefully. If you have doubts about the successful completion of the overclocking procedure, then it is better not to start it. Incorrect actions can result in device damage.

Correcting BIOS settings

Before overclocking the processor through the BIOS, you must carefully study the instructions for the motherboard. You can find all the necessary values ​​in it. In addition, it indicates the presence of special switches on the board that are responsible for increasing performance. Their use can also improve system performance.

The clock frequency is increased using the BIOS by changing the FSB bus multiplier. This feature is only supported by processors with an open multiplier. Otherwise, you will have to resort to software overclocking or soldering contacts. IN technical documentation The motherboard must include information about the FSB bus multiplier.

To overclock the processor through the BIOS, you must perform the following steps:

If after downloading operating system a blue screen appears or discs are not recognized, sound cards or other elements, it means that the acceleration threshold has been exceeded. You need to reduce the coefficient and try again.

After completing these steps, you need to check the processor temperature (help special programs like Everest or HWmonitor). The maximum permissible value at peak loads is 900C. If the indicator exceeds the permissible value, then it is necessary to reduce the coefficient or ensure sufficient cooling.

It is better to gradually increase productivity, increasing the final value with a certain step. Upon reaching required frequency You can stop, or you can continue to build it up. When the maximum value is reached, the computer will stop turning on.

To restore normal operation, you need to reset the BIOS settings. This can be done by removing the battery on the motherboard for ten seconds. If the computer still does not turn on, then you need to remove the battery and close the jumper marked CCMOS. It is usually located next to the battery socket.

Having found the optimal value, you need to work at the computer for half an hour. If during this time the temperature did not increase and there were no system failures, then everything is in order - overclocking was a success. Now you don't have to worry about how to speed up your processor.

Software overclocking of the processor

The debate about how best to overclock hardware continues. Security advocates blame the unreliability of the software, while those who prefer overclocking the processor through the program argue that it is easy to use. With the right actions, any method will be effective

There are several manufacturers of motherboards. Overclocking programs are also aimed at various manufacturers. Overclocking intel processor the wrong utility can cause serious harm to the system. In places where such programs are downloaded, information about the list of supported processor models and motherboards is usually posted. Therefore, before overclocking your intel processor, it is better to check the above-mentioned list.

ASRock OC Tuner

A simple and functional program for overclocking the processor. OC Tuner combines overclocking and monitoring functions. With its help, you can not only overclock the processor, but also obtain information about the state of the system, monitor the voltage in various elements systems.

To change the processor frequency and bus frequency multiplier in the “Over Clocking” section, just set the necessary parameters in the appropriate fields and click the “Go!” button. Along with the processor performance, you can also adjust the PCIE bus frequency. Voltage control works on the same principle, only there are more input fields (CPU, RAM, VTT, chipset bridges). A suitable program for overclocking an Intel processor.

MSI Control Center II

The program is designed to monitor the state of the system and its overclocking. The entire utility interface is divided into two main sections: “Oveclocking” and “Green Power”. Functions for overclocking the system are grouped in the first section. It also contains information about the status of devices: temperature, power consumption, etc.

The second section, “Green Power,” contains information about the overall energy efficiency of the system. You can also turn LED indicators on and off from this menu. motherboard.

ASUS TurboV EVO

A program for overclocking motherboards manufactured by ASUS. Owners of motherboards from this manufacturer can instantly overclock their devices without studying the BIOS and other subtleties. To do this, just install TurboV EVO. Moreover, in some versions of EFI BIOS the utility is built-in.

Using TurboV EVO you can control the processor clock speed and adjust the RAM frequency. The program also supports voltage control functions in various system elements. It is possible to automatically overclock the system.

AMD OverDrive

How to overclock an AMD processor? There is an excellent AMD OverDrive utility for this. The program has several levels of settings. They adapt to the user's level of awareness. For inexperienced users access to monitoring the operation of the system will be opened. Those with a sufficient level of knowledge will be able to adjust the bus frequencies and clock multiplier.

Besides fine tuning frequency of each core, OverDrive allows you to test the system with the selected settings. Monitoring functions make overclocking much easier AMD processor. OverDrive worked powerful utility to fine-tune systems to suit your needs.

Another useful program for overclocking a processor is CPU-Z. This good remedy monitoring the system status. The AMD processor overclocking program provides information on its operation. Its model, the overall clock frequency and the frequency of each core, the bus multiplier and much more other information.

CPU-Z portable program, which does not require installation. System information becomes available immediately after startup. In addition, the utility has a function for publishing and comparing the results obtained, which allows you to monitor the progress of other users who have decided to overclock the processor.

Overclocking central processor— forced increase in clock frequency. Increasing the clock speed, in turn, increases the processor's performance. Thus, you can get rid of unnecessary expenses on purchasing a new processor. And, nevertheless, it is worth understanding that the laws of physics cannot be outwitted! Overclocking entails an increase in power consumption, processor wear and increased heat generation.

What measures need to be taken before overclocking?

Each processor has its own limit for increasing the clock frequency; exceeding it will lead to failure. If we talk about Intel processors of the popular Core i3, i5, i7 series, they can be overclocked by a maximum of 15 percent. K-series processors are the best overclocked, but only with an unlocked multiplier.

In addition, it is worth knowing that after passing a certain temperature threshold, the overclocked processor begins to skip clock cycles, which reduces performance. It follows from this that you will have to check and, if necessary, improve the cooling system and, possibly, replace the power supply. Therefore, it is better to calculate all costs in advance; it may be more profitable to simply replace the processor.

Before overclocking, you need to check:

• BIOS version, it must be the latest;
• reliability of the cooling system;
• availability of overclocking software;
• test the processor, for example, using the S&M utility ( download).

Programs for overclocking Intel processors

SetFSB - download

The main advantage of the program is that overclocking can be done on the fly by moving the sliders. After changing the clock frequency, you do not need to restart your computer. Using the utility, you can overclock both outdated and new processor models.

The program does not support all motherboards; you can find out which models are supported on the program’s official website. Of course, if you do not consider yourself an advanced user, it is better to forget about this matter.

After launching the program, in the Clock Generator menu you need to select the model of the clocker installed on your motherboard. Next, click the Get FSB button; the window that opens will display the current frequency of the system bus (FSB) and processor. Carefully move the window slider in as small steps as possible, checking the current processor temperature. Having selected the optimal clock frequency, you can press the Set FSB key.

The disadvantage, or perhaps the advantage, of SetFSB is that the settings are saved until the computer is rebooted. You will have to overclock the processor every time you start Windows.

CPUFSB - download

This program is best at overclocking processors. Intel Core i5, i7. It works with a variety of motherboards, there is a Russian version, and the interface is as simple as possible.

In the main menu you need to select the motherboard manufacturer and chipset model. The next step is to click the “Take frequency” button, after which the current processor clock frequency will be displayed. The clock speed increases in small steps, but this must be done carefully. As in the previous application, overclocking persists until the system is rebooted.

SoftFSB - download for free

One more thing convenient application to increase clock speed on the fly. It also supports most famous motherboards. True, unlike the two previous programs, this one is free. The main disadvantage of the utility is that it is no longer supported; therefore, it will not work with new hardware.

In the FSB select menu, you must specify the model of the board and clock generator. Next, you should press the GET FSB button to capture the current clock frequency. The frequency also increases with the help of sliders.

All of the above programs are easy to use. Of course, advanced users overclock the processor in the BIOS, but this requires knowledge and patience - you need to restart the computer every time after making changes. All three programs allow you to overclock Intel processors on any computer, but if you have a laptop, you should be careful not to increase the frequency to the maximum values.

Using the experience of other users, we can confidently say that the universal and most commonly used programs for overclocking the system are:

• setFSB;
• CPUFSB;
• SoftFSB.

We will talk about them, but at the end of the article, but first we will study the theory and carry out preparatory work.

What is important to know before overclocking an Intel processor?

Of course, you can immediately go to the end of the article, download the software and get started. But thoughtlessly, without understanding the process itself, pressing the “pedals” in the program can lead to a somewhat unexpected result. And the instructions say that this software is intended for “experienced users.” Therefore, for now, we just read and delve into it.

Frequency increase

So, an increase in system performance can be obtained by increasing the clock speed of the central processing unit (CPU) or the system bus (FSB - front system bus). But most modern CPUs do not allow increasing the clock frequency, because this limitation is imposed by the computer manufacturer. In this case, it is necessary to increase the FSB clock frequency. At the same time, you need to understand that changing the system bus parameters will entail a change in the operation of not only the CPU, but also other modules of the personal computer - memory, video card or network card.

Changing the multiplier

The frequency at which the processor or system bus operates is the clock frequency of the generator itself, multiplied by some number, a multiplier. You can determine the multiplier using specialized computer testing software, such as CPU-Z. In essence, “overclocking” is an increase in this particular parameter. You can change it both in the BIOS subsystem, before loading the operating system, and using programs launched already under the Windows operating system.

Increasing supply voltage

Increasing the clock frequency multiplier often leads to unstable operation of the system as a whole and does not give the expected effect without increasing the supply voltage. This is especially noticeable with a significant increase in multipliers. Consequently, it is necessary to increase the supply voltage of both the processor and the bus itself. However, when changing the voltage, care must be taken not to exceed the permissible limits. Also, you should be aware that increasing the supply voltage inevitably entails an increase in the CPU temperature and the need for effective cooling.

Preparing to overclock the processor

We have studied the theory and finally move on to practice.

We go into the BIOS and see if the manufacturer allows changing the frequency multiplier, processor supply voltage, etc. We are not changing anything for now, we are just studying the situation. We also find a jumper with the inscription “clear cmos”. It will be useful to us if, by changing the parameters, we cannot start the computer.

We boot the computer and run the CPU-Z program. This is free software and can be easily found and downloaded online. We study the system in detail, the current values ​​of frequencies and multipliers. There, on the Internet, we find another program - HWMonitor. Using it, we determine the current readings of the system temperature.

We try to load the computer with a stress test from the first program and measure the temperature with the second program.

If the temperature values ​​exceed 60 degrees without “overclocking”, you can stop there. Unfortunately, this system cannot be overclocked.

If the temperature test passes, you should search the Internet for information about the processor and motherboard installed in the computer. In addition, you need to determine which PLL chip - frequency generator - is installed on the motherboard. We need this information when using specialized software.

Overclocking an intel processor on a laptop

Let's take a short break and talk about laptops. The situation here is not very good, because laptop hardware systems are the worst to overclock, and there are several reasons for this:

• an “overclocked” processor generates more heat, and cooling a hot chip in the limited space of a laptop case is quite a task;
• The laptop power system is not designed for the increased power consumption of an “overclocked” processor or bus;
• find the necessary data (find out the frequency generator chip and select software) to overclock the processor or laptop FSB programmatically It doesn't always work out. And if it succeeds, then practical implementation crashes - the system freezes for one reason or another: either the laptop’s memory cannot operate at the specified frequency, or the built-in video card fails.

Therefore, laptop manufacturers limit as much as possible the possibilities of increasing the processor or bus frequency, as well as voltage values, using the BIOS subsystem.

Despite all this, sometimes it is possible to increase the performance of standard laptops, but at the same time, as side effects, we get an increase in fan noise and a decrease in time battery life laptop.

Overclocking the processor via BIOS

Let's continue! The simplest method, used since the days of the first Pentiums, is to increase the frequency values ​​directly in the computer BIOS. Modern BIOS subsystems do not always allow you to change the set parameters, but if the manufacturer provides such an opportunity, then a wide field of activity is open to the user. The screenshots below show an example of BIOS settings before and after overclocking.

Changed parameters are marked in red.

If, after adjusting the values, the system freezes and access to the bios setup is impossible, you should reset the default settings by closing certain contacts on the motherboard or removing the battery.

Programs for overclocking Intel processors

If the motherboard manufacturer has limited overclocking capabilities by changing settings in the BIOS, you can try to overclock the system using special programs.

SetFSB

A very popular program among overclockers. Allows you to set the bus frequency, contains a large PLL database. It’s easy to work with the program, but it’s just as easy to crash the operating system. Therefore, we change the frequency values ​​smoothly, in small steps.

An unpleasant nuance. Starting from version 2.2.134 - the program is paid, the setfsb button is inactive, mode command line doesn't work. There are two solutions to the problem: either use older versions of the software, or look for ways to register later versions.

So, step by step:

• select “our” clock-generator
• press the “get fsb” button
• smoothly move the slider a couple of steps
• press the “set fsb” button

We determine the stability of the system using stress tests. We repeat until we get BSOD or satisfaction from overclocking. Since all manipulations are performed only at the time the program is launched, after restarting the computer, the original settings are returned. To permanently use clock frequency settings, you must enable command mode programs. Details are specified in the setfsb.txt file in the program folder. The same file contains a list of supported motherboards and frequency generators.

CPUFSB

Similar in its functionality application. In this case, there is a correct translation into Russian.

Essentially, CPUFSB is a dedicated CPUCool software module - a utility for monitoring and overclocking the processor. The program supports a large number of motherboards from various manufacturers.

The operating procedure is similar:

• select the type of motherboard;
• select the PLL chip type;
• “take frequency” - get current values;
• change the current frequency values ​​- “set frequency”.

Frequency settings are saved until the system is rebooted.

SoftFSB

Another application for changing the clock frequency of the bus or processor. Unfortunately, the program is not currently supported by the author. Therefore, on modern systems may not start because it “does not know” about the latest PLL releases.

The principle of operation of the program is the same - select the correct motherboard and clock generator, read the data, smoothly change the current settings and write them.

Consequences of overclocking are the user's responsibility

As a result, we have the following:

• overclocking a computer involves increasing frequencies and voltages;
• You can change the frequency values ​​both in the BIOS and programmatically;
• Overclocking software is identical in its operating principle. The differences between the utilities lie in the ability to support particular equipment;
• not every equipment can be “overclocked”;
• increasing frequencies and voltages should occur step by step.

And most importantly -

Responsibility for all actions taken related to changing the standard settings of the equipment rests entirely with the person who made these changes.

Perhaps many people know, but for those who don’t, we’ll tell you that the performance of any computer can be significantly increased not only by replacing the existing hardware to a new one with higher performance, but also as a result of overclocking the old one.

Overclocking or overclocking involves increasing the performance of PC hardware components such as processor, video card, RAM, and motherboard by improving their nominal characteristics. In the case when the processor is overclocked, we will increase its clock frequency, multiplier coefficient, and also the supply voltage.

How to increase frequency

So, how to overclock an intel processor? When talking about methods of this type, let's start with increasing the frequency characteristics. Where does this opportunity come from? The fact is that manufacturers of microprocessor technology always supply their products to the market with a certain safety margin, the value of which ranges from 20 to 50% of the characteristics stated in the passport. For example, the Intel 2.5 GHz installed in your PC has a maximum clock speed of 3 GHz.

In other words, during a properly executed overclocking process, you can achieve an increase in its characteristics to 3 GHz. However, this does not mean that in this mode it will work longer than at its nameplate frequency. When the processor gets very hot, the peak frequency is reset to minimum values. In addition, there is absolutely no guarantee that you will be able to increase this figure, but some simple manipulations will easily increase it by 20-30%.

Each processor is characterized by the presence of such a parameter as a multiplier. If you multiply the value of this parameter by the FSB bus frequency (BCLK), we find out the frequency. Therefore, the simplest and absolutely safest method of overclocking Intel is to increase the frequency of the FSB system bus (BCLK).

The accessibility and simplicity of this method comes down to the fact that changing the FSB (BCLK) can be done directly in the BIOS, as well as programmatically, using a step equal to 1 MHz for this purpose.

In more “ancient” models, using such a method could lead to dire consequences - the processor could simply burn out. Today, in order to “kill” modern multi-core Intel only by increasing its clock frequency, incredible efforts will be required. But we do not set such a goal, and, therefore, this method is completely safe.

In the event that a novice overclocker even overdoes it with the settings, the system will instantly reset installed settings, will reboot and function in its normal mode. To change the bus frequency, go to the BIOS, then find the value of the CPU Clock value, press the “Enter” key within this value, and then enter the value of the bus frequency.

Attention! It is recommended to overclock only desktop processors. It is better to leave processors in laptops in their current state, because... they cannot cope with the increased heat generation of processors under overclocking. To enter the BIOS, you usually use the “Del” key when booting the PC. Read this article: . But only to familiarize yourself with the frequency and other parameters.

So, we enter the BIOS, open the information about the CPU and see:

Set new values ​​in the FSB or BCLK line settings. In this screenshot, BCLK is equal to 100 MHz, which when multiplied by a factor of 33 gives a processor frequency of 3300 MHz. If you set the BCLK value to 105, the final frequency will be 3465 MHz. Remember that most modern Intel processors are sensitive to changes in this value. It is better to overclock them by increasing the multiplier. Read about multipliers below.

In order for the overclocking result to be as effective as possible, it is necessary to replace the existing cooler with a more efficient one. To determine the efficiency of a particular fan model, you should measure the Intel temperature at its maximum load. Programs such as Everest and 3D Mark will help with this. If the temperature at maximum load is 65-70°C, it is necessary to either increase the fan performance to the maximum value, or reduce the FSB bus frequency (BCLK).

How to change the multiplier

Also, increasing productivity can be achieved by changing the multiplier. This is only possible if the existing “stone” is unlocked with a multiplier. As a rule, such devices are labeled “Extreme”. If the version of your existing Intel does not belong to this category, you should not be upset, since using the first option will be enough to obtain it. Or you cannot do without increasing the voltage.

We change the multiplier upwards from the standard one, as in the screenshot.

There is no need to set large multipliers right away. Try adding 2-3 units to start. Save and restart your computer. If it works stably, you can add another unit. And so on until stability is disrupted. Let's assume that the computer freezes when turned on after setting the multiplier to 45. Then it is better to set the Final multiplier to 43. This way the computer will work stably.

If the motherboard cannot reset the settings on its own, help it. You need to remove the round battery on the motherboard. If you don't know what it looks like, it's better not to overclock your processor!

How to increase the supply voltage

How to overclock an intel processor by increasing the processor voltage? The principle of increasing productivity by increasing voltage is quite simple. To implement it, you just need to increase the power supply of the device. In order to make your dreams come true, you must:

1. install a more efficient cooler;
2. do not increase the voltage value higher than 0.3 V from the nominal value.

In order to increase the voltage, you need to go into the BIOS, find an item called “Power Bios Setup => Vcore Voltege” or something similar, increase the supply voltage by 0.1 V. Then, you need to set the cooler to the maximum value and set a higher FSB frequency (BCLK) or multiplier.

What is overclocking? This is a change in the normal operating mode of computer devices in order to increase their speed and improve overall system performance. Apart from extreme overclocking, the goal of which is to squeeze the maximum out of a component and set a record, overclocking makes it possible to meet the growing needs of applications and games without replacing hardware with more powerful ones.

Today I will tell you how to overclock your processor (CPU). Let's consider the methods and means by which the performance and stability of an overclocked system are determined, as well as a simple way to return it to the “pre-overclocking” state.

Before you start

Any modern processors, even mobile ones, are capable of overclocking, although the latter, according to their creators, is contraindicated due to the inability to provide adequate cooling. Yes, an overclocked “stone” (from now on we will mean stationary PC processors) consumes more energy and generates more heat, so the first thing you should take care of is a good cooling system. It can be of either air or liquid type, the main thing is that the size of its heat sink ( TDP) matched or exceeded the thermal power of the “stone”. For small and intermittent overclocking, the boxed cooler that came with the CPU is sufficient, but under increased load it will most likely irritate you with loud noise.

The second important part is the power supply unit (PSU). If his strength is barely enough to meet the current energy consumption of devices, he will not be able to overclock. To calculate the required power of the power supply taking into account overclocking, use online calculator: Select from the lists the components that are installed on your PC and click " Calculate».

Calculator version " Expert» allows you to take into account the voltage and clock cycles of the CPU after overclocking, as well as the percentage of load on it (CPU Utilization). Choose the latter to the maximum – 100%.

Attention! The test shown in the screenshot puts a lot of load and heat on the processor. Only run it when you are sure there is sufficient cooling. And never run it on laptops - it can damage the device.

Overclocking techniques

There are 2 main methods of overclocking a CPU: by increasing the reference clock speed of the FSB (the group of signal lines on the motherboard that provides communication between the processor and other devices) and the processor multiplier (the number by which it multiplies the bus frequency; the result of this operation is frequencies of the “stone” itself).

The first parameter is controlled by the BCLK clock generator on the motherboard (otherwise called a clocker or PLL chip). The second is the percentage itself. To change the CPU multiplier, it is necessary that it be unlocked for increase, and not all models can boast of this. "Stones" with an unlocked multiplier, e.g. Intel K-series or AMD FX, are overclocked to higher rates than simple ones, but also cost more.

Overclocking via the FSB bus involves increasing the frequency of the BCLK clock generator. This is a risky method, since along with an increase in bus speed, the speed of the memory increases (solutions where the CPU and memory are overclocked independently of each other are rare), and on older motherboards, so do other devices connected to peripheral buses. In a word, the entire system goes into abnormal operation mode. However, if you have more or less new computer, overestimating the reference frequency is unlikely to damage it. If the value is set too high, the system will simply restart and reset it to default.

You can overclock the CPU on the bus both under Windows - using utilities, and through BIOS settings. The disadvantage of the first method is selectivity, since the utilities support a limited range of devices. Some of these uliliths are produced by motherboard manufacturers, but they are not intended for the entire line of their products. Lists of devices that are supported by a specific program are usually provided on official websites or in the documentation for the programs.

Overclocking only speeds up the processor by increasing the multiplier, since the reference frequency remains unchanged.

We accelerate the “stone” using programs

As an example, consider a utility that supports various BCLK generators of both old and modern motherboards. Before using SetFSB, find out the exact model of your generator - find it on the board itself or look in its documentation.

The BCLK generator might look like this:

Or have a more elongated body shape. But I think you'll figure it out.

After starting the program:

• Select from the list " ClockGenerator» your PPL chip.
• Click " GetFSB", so that the program determines the current clock cycles of the system bus.
• In short steps, move the central slider (marked 3 in the screenshot) to the right side, while simultaneously monitoring the CPU temperature. SetFSB does not have a device thermal control function, so use other tools, such as utilities SpeedFan , HWMonitor and analogues.
• Having selected the optimal bus speed, save it by pressing " SetFSB».

If something goes wrong, just restart your computer - the settings will be reset.

Other overclocking utilities:

• EasyTune6– designed for Gigabyte motherboards.
• DualCoreCenter– the same for MSI boards.
• AMDOverDrive– for AMD processors.
• ASUSTurboVEVO– for some motherboards manufactured by Asus . In addition to the version for Windows, it can be included in the set of UEFI utilities (graphical analogue of BIOS).
• SoftFSB– a program similar to SetFSB, but long abandoned by the author. Suitable for very old computers.
• CPUCool and the accelerating component included in it CPUFSB- also somewhat outdated, but still relevant.

Overclock via BIOS

Overclocking a “stone” by changing BIOS parameters is no more difficult than using programs. The main thing is not to rush.

In the BIOS Setup or UEFI graphical shell settings (the screenshot shows the “ A.I.Tweaker» UEFI motherboard ASUS boards) we are interested in the following options:

• CPUClock(can also be called FSB Frequency, External Clock, Frequency BCLK, or as I call it – Frequency BCLK) – FSB reference frequency.
• CPU Ratio(CPU Clock Multiplier, CPU Frequency Ratio, Ratio CMOS Setting, Multiplier Factor, etc.) – CPU multiplier.

As I said, multiplying the values ​​of these two options gets the processor's natural frequency. In my example it is 3500 MHz. (200*17.5).

To improve CPU performance, you can change one or both of these settings. So, to raise the frequency of the “stone” to 4000 MHz, it is enough to increase the CPU Ratio to 20, and leave the FSB Clock the same. But if the multiplier is blocked, you can only work with the FSB bus.

The FSB Clock value is increased in steps of 5-10 Mhz, after saving the setting, rebooting the PC each time and monitoring the CPU temperature in the BIOS.

With a significant increase in CPU Ratio and FSB Clock, it is sometimes useful to slightly increase the processor's supply voltage (option VCORE Voltage, CPU Core, CPU Voltage, etc.). In my example, the CPU Offset Voltage will change. The change step is 0.001 V. However, do not get carried away, since when this indicator increases, the temperature of not only the “stone”, but also the VRM elements (voltage regulator of its power system) will increase, which can damage them.

Since FSB acceleration affects the performance of RAM, to increase the stability of an overclocked system, experienced overclockers change its frequency to the minimum value so that it has room to grow. IN different versions The BIOS option is called Memory Frequency, SDRAM Frequency Ratio, System Memory, etc.

Some additionally disable CPU energy saving technologies - Turbo Core, Cool'n'Quiet, C1E, etc., to maintain the achieved performance under high loads. But this is only advisable for those who constantly load the computer to the maximum.

What should be the temperature of the overclocked “stone”

Modern processors normally tolerate temperatures of 80-85 degrees, but it is still better not to allow stronger heating. Accordingly, without load, the temperature of an overclocked processor should not exceed 55-60 degrees.

For older CPUs, the temperature maximum is 65-70 degrees, and heating without load should not be higher than 35-45 degrees.

Testing the system for stability

How stable an overclocked computer will work can be determined by the same utilities that you used to check it before overclocking. I use the OCCT (OverClock Checking Tool) program, so I’ll take a closer look at its tests.

We are interested in how the main components of the PC - CPU, memory, chipset and power supply - will hold the load. I recommend starting with a comprehensive check of the first three nodes. If the test passes without errors, then there should be no problems with them during normal work. In case of instability (errors recorded by the program, reboots, shutdowns, blue screens death), we reduce the number of loaded nodes to 1-2 and, using the method of elimination, determine what exactly cannot cope.

During testing, OCCT displays in the window " Monitoring» the main parameters of the system - load levels, temperature, voltage, etc., and after the end of the test saves them in the form of graphs.

So, a comprehensive check of the CPU, chipset and memory - “ Large dataset» launch from the tab CPU:OCCT. Time: 1 hour. Type – Auto. To start, press the button " On" and watch the changes in indicators in the window " Monitoring».

If the test fails, select " Average data set» – checking the processor and memory. Or " Small set"- just a proca.

We have already considered the next test. This CPU:Linpack, which heats up the CPU to the maximum. It makes it possible to identify problems that arise under extreme load.

The Linpack test duration is also 1 hour. Set it to the same settings as during the test before overclocking: maximum memory - 90% and checkboxes next to everything below.

The last thing you want to know is whether the power supply can handle the new load. For this purpose, the OCCT program provides a test PowerSupply. It forces the elements of the power supply to work at maximum efficiency, so a weak or low-quality power supply may not withstand it. In a word, if you are not sure, it is better not to take risks. However, a weak power supply is unlikely to satisfy the “appetite” of an overclocked system.
