I got 8500 OEM 230/230. I did flash BIOS to Retail 275/275. Did the volt mod on GPU to 1.78V, and mem was at 3.5V. Now, I can go with the ram up to 300 MHz with no prob, after that I get black faces and white hand on ppl in Lobby High detain in 3DMark 2001. But GPS starts having face and hands problems after 270MHz. All the other tests have no problems up to 290/310. Should I ignore this high detail problem and go up?? And why I can't go any higher with GPU????
