| Abstract: | This article presents ways of boosting the performance of a personal computer (PC) through overclocking. Overclocking is a trick that PC tweakers have been using for years to get free speed out of their systems. It is simply a matter of carefully changing some settings. Overclocking will not turn an ancient PC into a powerhouse, but it can help you squeeze every drop of performance out of your machine. Two variables set the speed at which your central processing unit (CPU) runs: the system bus speed, and the CPU clock multiplier. To determine the actual operating speed of the CPU, those two values are multiplied together. Some motherboard and CPU combinations let you change one or both of those variables, setting a new speed for the CPU. Boost either setting and you're officially overclocking. Overclocking can increase the CPU speed by 10% to 20%. The trick to overclocking is in knowing when to stop. Crank up the speed completely beyond the operating limits of the CPU, system bus, or random access memory, and the PC will crash or freeze a lot. If you have set the clock too high on a system that holds the dock settings BIOS, it may fail to boot, and you will have to use the PC Setup program to reset the dock settings stored in CMOS RAM.
