Sometimes abbreviated as OC, overclock is a method of configuring a computer to perform faster than its advertised speed. Overclocking is accomplished by setting or changing jumpers, dip switches, CMOS (complementary metal-oxide semiconductor) settings, firmware updates, or using software utilities. Overclocking allows users to get a performance boost and is often performed on the computer's CPU (central processing unit) and video card.

Overclocking should only be performed by advanced computer users or users aware of its risks. When overclocking a computer, you may experience random errors or lockups related to heat and will void your warranty on the hardware device and possibly the computer or motherboard. Finally, overclocking can sometimes damage or destroy computer components.
