I have an a7v8x-x and a sapphire radeon 9600 pro. The mobo, according to the manual, only supports 1.5v agp cards, however I read several posts over at http://www.rage3d.com about ati tech's recommending people switch to 1.7v agp to get the best from thier radeons. Was just wondering if anyone knows of a way to give the graphics card that little extra juice on this mobo?
