To run a
microprocessor faster than the speed for which it has been tested and approved. Overclocking is a popular technique for eking out a little more performance from a system. In many cases, you can force your
CPU to run faster than it was intended simply by setting a
jumper on the
motherboard. Overclocking does come with some risks, however, such as over-heating, so you should become familiar with all the pros and cons before you attempt it.
Overclocking is sometimes called speed margining.
