All my previous clocking on this were done with the Quantum editor using my stock BIOS and I've had a heck of a time getting good results from my OCing. Well, yesterday I decided to modify my BIOS using a Hex editor and took steps to correct the checksum as well. Now everything works great and I am now stable in 3DMark05/06 firefly test (which use to lock up @ 850MHz) and I am also getting better results in CF using WiC benchmark.



My current clocks are 850/900/1.25V. I ran WiC @ 1920x1200 w/ everything on high and AA/AF disabled.

Avg: 46
Min: 22
Max: 140

Can anyone explain why I'm getting much better results? Could the invalid checksum have caused conflicts with CF and Catalyst drivers? I can't think of any other reason why I am problem free at these clocks. I am sooooo happy right now.

Final question. What are the upper limits in regards to core/VRM temps for the HD2900XT? Is there a white paper out there some where? Right now my temps are GPU1/2: 87/85 VRM: 80/77 while running 7 consecutive benchmarks in WiC.

Thanks guys......
I did not overclock and have an equal increase in fps in Wic. Probably due to new catalyst 7.12 drivers or new patches. Current Wic version update i think is 1.005.
