A Using non standard BIOS settings to boost processor performance by around 10-30%.Overclocking a processor involves using non-standard settings to gain performance over and above the base levels set by the manufacturer. In many cases manufacturers release slightly more expensive versions of their standard chips that are specifically designed to be overclocked. Intels K range of chips and AMDs Black chips are all relatively easy to overclock, and normally allow 10-30% performance gains simply by changing the multiplier setting in the BIOS. Overclocking is easy, relatively risk free and essential for value aware users. Learning how to overclock a CPU with no prior knowledge, apart from a reasonable understanding of technology, would take most people less than a day. Google your specific motherboard/CPU combination for further info.
