Powertweak is a hardware optimizer. Powertweak configures the internal chipset and processor registers, in order to make them perform at the highest levels. It works by adjusting settings that optimize the speed and consistency of the data transfers between the different components. PowerTweak works with most of the newer processors and chipsets, including ones made by Intel, Cyrix, AMD, 3Dfx, Sis, VIA and Ali. Powertweak was formerly named SysEnhance II.
