cpupowerd
A daemon which controls the frequency and voltage of CPUs.
This userland program adjusts the frequency and voltage according to the CPUs load.
Its capabilities include overvolting as well as undervolting.
Currently it supports only AMD K8 processors like Athlon, Athlon64 (X2), Sempron, Opteron, Turion ...
Using lower voltages could make your hardware quietly and maybe longer living, too.
Laptops could work longer in akku mode.
