Overclocking
ME CLOCK'S ON FIRE, BURNING HOT, HOT, HOT!
Expert computer users continue to debate the overclocking of PCs. "Overclocking" means increasing your system bus speed or your CPU clock multiplier to make your system run faster.
For example, a Pentium 100's bus speed is 66 MHz (66.4 to be exact), and the
multiplier is set at 1.5x. By switching jumpers on the motherboard, change
the multiplier to 2.5x, making your PC a virtual "Pentium 166."
Why doesn't everyone make this zero-cost "upgrade"? It voids your warranty, it doesn't work on all systems, and even when it does, it is risky. The heat generated by an overclocked system can prematurely burn out chips and components. You can buy a second fan, or replace your existing CPU fan with a high performance model. This reduces, but does not eliminate, the chance of heat-related failure.
Overclocking is a like driving 80 mph on the highway. You will be a little faster, and you will probably get away with it, but you are gambling that nothing bad will happen.
