Setting CPU Speed
Unfortunately, it's not always so easy to set the clock multiplier and FSB speed. You will need to do some research to determine the proper method for your particular system.

Researching Your System
Depending on the design of your motherboard, you can set your system's FSB speed and clock multiplier either through its BIOS, with DIP switches, or with jumpers. However, don't even think of attempting any of these changes without first reading our pointers for cooling your system, and our warning about the very real dangers of overclocking.

If you're lucky, your motherboard includes a BIOS utility for configuring bus speeds and multiplier options. This is the best situation, because it facilitates experimentation. Unfortunately, only a few motherboards currently offer this option, notably Abit's BH6 and BX6 boards.

If your motherboard doesn't have a BIOS utility, it might utilize DIP switches to select the settings for both the CPU multiplier and bus speed selection. DIP switches are relatively easy to set, as long as you can get information on the proper settings.

In the absence of either of these two methods for setting CPU options, you'll almost certainly find the venerable old jumper on your motherboard.

Jumpers are relatively easy to set, but they require a case that allows access from a variety of openings. Nothing is more frustrating than having a jumper slip out of your hands to disappear somewhere inside the case.

Check the manual that came with your motherboard or your system for details on whether to use BIOS settings, DIP switches, or jumpers. Some systems also have this information written on a sheet pasted inside the system case. Failing that, your motherboard manufacturer's Web site might have the required details.
