You guys may find this a little wierd aswell. I have a Club 3D x800 pro Vivo, which I used to have unlocked with XT PE bios @ XT PE speeds, but I experienced instability, so I took it back to my old x800 pro vivo bios, except I kept the 16 pipes. Now heres my problem, the card simply does not want to OC. I currently have the GPU at 515mhz( 8% OC)) and the ram at 536 (19% OC), and I know most people have been able to get an extra 50 mhz ontop of what Im getting. The part that urg's me is that my card idles at 34C, and under Load it hits 39C, I have a Zalman VF-700 CU on it along with OCZ BGA ram sinks. The card is cool as can be, Shouldn't I bet getting a higher OC then that? Is a voltmod all I need? Or should I try more Bios?
