Overclocking a computer

Very often, users want their computers to work faster, but they do not want to update the configuration components, using other methods to speed up the activity. There is such a thing as overclocking a computer, which is usually understood as increasing the frequency of its components, which significantly increases the speed of their work, and, consequently, the overall performance of the computer as a whole. It is worth to understand this concept in more detail.

Overclocking the computer is possible because the manufacturers have a certain margin of safety in the manufactured products. At the same time, within a single batch, machines can differ in performance. Here you will notice that some processors work faster, while others are slower. In this case, the manufacturer does not make sense to deal with the whole batch of devices, by searching each with subsequent testing, therefore, for the whole lot, the minimum optimal value is usually indicated, under which 95% of all products are guaranteed to fall. And the rest, in case of problems, will be replaced under warranty. All this was said in order to smoothly lead you to the fact that overclocking the computer is reduced to the procedure for releasing the hidden reserves of devices that are included in the computer. However, it is worthwhile to understand that such reserves may not be there, which leads to disastrous consequences.

Overclocking a computer can usually be done in one of three ways. You can briefly describe each of them.

Overclocking of the processor via the BIOS is done by selecting a special profile in the BIOS settings, which, when the settings are automatically set, allows the processor and the entire machine to be overclocked by 5, 10, 15% or more.

Another way is overclocking through special utilities, which are special programs. Usually they are attached together with the drivers to the motherboard.

And the most difficult can be considered manual overclocking, that is, a method in which the user himself changes the necessary BIOS settings.

As a classic method of overclocking, it is considered to increase the frequency of the processor by increasing the multiplier of its frequency. The processor does not have a built-in clock, so it operates at the frequency indicated by the motherboard. The processor frequency in this case is calculated by multiplying the clock speed of the system bus by the processor factor. It is about the increase of this factor that we are talking about. In BIOS settings there is a special function for this, which can be called differently depending on its version. In some versions, this is not allowed at all for security reasons. This is the reason for the appearance of a different method, which consists in increasing the frequency of the system bus. This, on the one hand, will allow not only to overclock the processor, but also the computer as a whole, however, devices that are connected to the system bus can start to work with errors. This is due to the fact that the operating frequencies of the devices are tied to the frequency of the system bus, which leads to an increase in the frequency of their operation with an increase in the frequency of the system bus. However, not every device can withstand this. If there are failures, you can either return the system bus frequency back, or change the frequency ratio of the device to its frequency, so that the frequency of the device does not change.

To ensure the stability of individual devices during overclocking, the voltage that is applied to the devices rises. This causes a strong heating, which requires more intensive cooling. Otherwise, the device can quickly fail, or the computer simply refuses to turn on.

If you are worried about the question of how to overclock the Intel processor, then here it is possible to say the following. There are no fundamental differences from the described methods, so it remains only to try everything in practice.
