What Are the Pros and Cons of Overclocking a PC?

Overclocking is a method of making various computer components run at higher speeds than the rated frequency.

Right!

Overclocking is a method to make various computer components run at higher speeds than the main frequency,

As the core CPU frequency of the machine, of course, it is very important, because it can directly affect the performance of the machine processing tasks. ^[1]

Under normal circumstances, the CPU FSB and memory FSB are the same, so when you increase the CPU FSB for overclocking, you must also increase the memory FSB to work with the CPU at the same frequency. For example, we have a platform, the CPU is early Athlon XP 1800+, KT600 motherboard, DDR266 memory. Athlon XP 1800+ has a default external frequency of 133MHz, a default multiplier of 11.5, and a main frequency of 1.53G. Since Athlon XP 1800+ is locked, you can only overclock by increasing the external frequency. The frequency is increased to 166MHz. At this time, the CPU main frequency is 166MHz × 11.51.9GHz.

As we have increased the CPU FSB to 166MHz, if you are using DDR333 or higher specification memory, then setting the memory frequency to 166MHz is a standard frequency, but here is DDR266 memory. In order to meet the CPU overclocking requirements, the memory must also Overclocked from the original DDR266 (133MHz) to DDR333 (166MHz).

Although overclocking can get the computer to achieve higher performance, it will eventually be overloaded, which will cause the computer to run more or less unstable, frequent blue screen freezes or freezes. After overclocking a certain step, it will affect the operation of other components, which is the so-called "moving the whole body with one stroke". Therefore, it is suggested that if you only need a higher processing performance temporarily, we can appropriately overclock the hardware temporarily and overclock the computer for a long time. Not only will not get a good operating experience, but it will easily damage the computer and lose important data.
