Overclocking is the process of increasing the clock speed of a computer's CPU or GPU beyond its factory settings. This is done to enhance performance, allowing the hardware to execute tasks faster. While it can lead to improved gaming and processing speeds, it also generates more heat and can affect system stability. To successfully overclock, users often adjust settings in the computer's BIOS or use specialized software. It's important to monitor temperatures and ensure adequate cooling, as excessive heat can damage components. Overclocking is popular among gamers and tech enthusiasts seeking to maximize their system's capabilities.
