What are the disadvantages of overclocking a CPU?

Disadvantages of CPU overclocking: affecting system stability, shortening the service life of hardware, and even burning hardware equipment. Overclocking will generate a large amount of heat, which will increase the temperature of the CPU, causing "electronic migration" phenomenon, damaging the internal chips of the CPU, reducing the life of the CPU; and the possibility of system crashes or errors will increase.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

—Generally speaking. Each CPU has its rated main frequency, FSB and multiplier. The method we use to increase the main frequency of the CPU by changing its FSB and frequency multiplier is called overclocking. In fact, it simply means changing the working frequency of the CPU. However. Because overclocking has certain harmful effects on the computer. Therefore, it is very necessary to have an in-depth understanding of its technical essentials and clarify the overclocking goals.

Overclocking will affect system stability, shorten the service life of hardware, and even burn hardware equipment (not only the CPU is affected!!!), so it is best not to overclock without special reasons.

Disadvantages of cpu overclocking

1. The stability of the computer is poor. Maybe it is quite stable to use the test software to test the computer when the screen is just overclocked, but as time goes by With the aging of computer hardware, when the computer runs different games for a long time, various unstable factors will surface.

2. After overclocking, the computer hardware life is relatively short.

3. Trigger the "electron migration" phenomenon

Overclocking will generate a lot of heat, which will increase the CPU temperature, thereby triggering the "electron migration" phenomenon. In order to overclock, the voltage is usually increased. In this way, more heat will be generated. However, it must be understood that it is not the heat that directly harms the CPU, but the "electronic migration" phenomenon caused by the heat that damages the chips inside the CPU.

The "electronic migration" phenomenon does not damage the chip immediately. Its damage to the chip is a slow process, which will more or less reduce the life of the CPU. At the same time, in the case of overclocking, the possibility of system crashes or errors increases.
