Overclocking. If you're unaware of the basic idea it's to get more out of something than it is initially designed to give. When dealing with processors the speed of your processor is governed by two factors. The FSB, Bus Speed or BCLK multiplied by, unsurprisingly, the multiplier. For example if you have a Bus Speed of 150MHz and a Multiplier of x10, you'll get a 1500MHz processor. So far, so easy. Intel has had the same methodology for their processors for some time now. If you want to overclock it's quite likely that you have a lower end processor and wish to get more for less money. However Intel processors have always had a locked multiplier at the base end of the market, with only the premium "Extreme" editions having a multiplier that can be adjusted up as well as down. You're therefore limited to pumping the FSB, or BCLK as it is now, up as high as you can get away to maximise the locked multiplier.
