Turning this switch to enable will automatically optimize the system for fast, yet stable clock speeds. (and than shows a picture of were it is located on MB). Tends to leave alot room for the imagnation.

HD7750 DCSL 1GBDDR5@ Maximum "Game" setting 850mhz on the clock, with voltage tapered to 995.
