■ Setting overclock
Overclock means to increase the processing speed of the CPU by increasing the clock speed of the CPU while leaving the CPU unchanged when fast CPU processing is required for special purpose. Increasing the CPU clock speed will increase the CPU processing speed, but it can overload the CPU, causing a lot of heat in the CPU, which can damage the stability of the CPU and shorten the lifetime of the CPU. Thus, limited use is recommended.
