Overclocking is the process of applying additional voltage to a processor to gain faster clock cycles and, in turn, faster processing of data. Computer software is used to achieve this.
History
In the past, overclocking required computer users to change jumpers on the motherboard to achieve higher frequencies. An upgrade came in the form of BIOS-managed overclocking capability. Nowadays, software compatible with operating systems can be used to overclock.
Monitoring Software
When it comes to processor overclocking, a good monitoring software is useful. CPU-Z is a top choice for monitoring every statistic in a computer's processor-memory infrastructure, from clock rates to voltage.
Tweaking Software
AMD chips can benefit from AMD's own processor overclocking software, AMD OverDrive, and Intel chips have Intel's Desktop Control Center. Additionally, many motherboards come with software packages that can be used to overclock installed components, including the processor.
Expert Insight
Although using overclocking software is risky, says Tom's Hardware, if you stay within certain limits, your processor should be safe from overheating damage.
Considerations
It's still best to make sure a processor has adequate cooling. Although overclocking can be achieved with standard retail heatsink/cooling fan combos, separately purchased fans often provide better overclocking performance.
