CPU multiplier

(redirected from clock ratio)

CPU multiplier

Also called the "clock ratio," it is the speed ratio between the computer's frontside bus (FSB) and the CPU. For example, a 10x CPU multiplier runs the CPU at 10 times the speed of the FSB. The CPU multiplier is changed in the BIOS setup. See overclock and multiplier lock.
