SetFSB is a popular program that allows you to change the system bus (FSB) frequency from within Windows. This frequency is generated by the clock generator chip on the motherboard. Since it affects the CPU frequency, you can overclock the CPU by raising it. SetFSB supports a long list of clock generators used on desktop boards and notebooks. Start the program, select your clock generator, get the current FSB, move the slider and press "Set FSB". Then test the system at this frequency. The setting is lost after a reboot, and recent versions need a paid ID to use Set FSB.
SetFSB allows users to overclock their CPU, potentially enhancing computer performance.
