Overclocking the processor
If you are not satisfied with the characteristics of yourpersonal computer, then you have several opportunities to improve the situation. You can upgrade the system, i.e. replace some of the components with new models, or "squeeze" out of the existing set maximum.
Now, when new computer componentsbecome more accessible, the issue of overclocking the system and, in particular, the processor is no longer so acute. However, there are still many systems in which an upgrade is impossible for one reason or another. In this case, overclocking is an excellent solution to the problem.
Overclocking a computer, it's overclocking (it's overclocking), it'sincrease the speed of computer components due to their use in forced (non-standard) modes of operation. You can overclock the central and graphic processors, operational and video memory. For overclocking, you can use BIOS tools or special utilities.
Important! Overclocking the processor significantly increases its temperature, so without a good reliable cooling system, it's extremely undesirable to start overclocking.
Most often overclock the CPU. Its speed is determined by two parameters: architecture and clock speed. Obviously, the architecture (structure) of the microprocessor can not be changed by the user, but it is possible to change the processor clock speed.
Why is overclocking possible? The fact is that the same processors, whichwork at different frequencies, constructively no differences. When testing a batch of processors at a single frequency (at all frequencies, it is very difficult to check each processor), some processors are discarded. If such rejected processors pass the test at a lower frequency, then they are appropriately labeled.
The manufacturer tests its products in a veryhard conditions, and therefore when working in nominal conditions (according to the manufacturer's specifications), the processors still have about 10-15% of the power reserve. This stock is used for overclocking.
Sometimes enough high-performance processors are deliberately labeled as slower, simply because it is beneficial for the manufacturer. Such processors will be able to overclock by 30% and even higher.
As already mentioned, You can increase the speed of the processor by changing its clock frequency. The clock frequency is defined as the product of the multiplier and the FSB frequency. It is through adjusting the settings of these two parameters and overclocking is performed.
Where can I adjust the frequency of the system bus and the multiplier? The simplest and most affordable option - BIOS.
Attention! Any manipulation with the settings of the system bus frequency and multiplication factor the user performs at his own risk and himself is responsible for possible damage or failure of computer equipment!
In order to enter the BIOS menu, it is necessary toboot the system by pressing one key or key combination on the keyboard. For most motherboard models, this is the "Delete" key. After entering the menu, you need to find the section responsible for setting the bus frequency. Usually such section is called "Advansed BIOS Features" or simply "Advansed".
In this section, find the parameter CPU Host Frequency (can also be called CPU FSB Clock, FSBFrequency, External Clock). This is the frequency of the system bus. Change the value of this parameter should be very smoothly - no more than 10-15% at a time. After the changes, you should exit the BIOS with saving and start the system.
It is necessary to check the stability of worksystem. Are there any "glitches", sudden hangs, blue screen (BSoD)? If the system works stably, you can go back to the BIOS and change the FSB value a little more.
In addition to the system bus frequency settings, experiencedOverclockers also change RAM timings, adjust multipliers and dividers, add or reduce voltage applied to the processor. Before proceeding to change the settings of these parameters, you should be aware of what exactly these parameters are responsible for, and what effect will be obtained.
To date, when the free salethere are 2-, 4-, 6- and even 8-core processors with a high clock speed, overclocking is more fun than necessity. Experienced PC users specially select to overclock certain processor models and corresponding motherboards in order to maximize the overclocking capabilities.
If you do not yet have enough experience or simply do not want to "mess around" with the settings, then maybe you just need to buy a new processor with the required speed.
