Re: GTX280 stuck at 3d speeds even at desktop.
It downclocks fine for a while then it stays at 3D clocks if you raise the load high for a decent period of time. It could be bios related to certain cards, I flashed my 280 with a newer bios from an XFX XXX card and it seems to work better than the older bios version my card came with. Mine came with 62.00.0E.00.02 and the XFX XXX had 62.00.0E.00.75, perhaps there was some changes made by NV in the core bios code who knows, but it's not as bad now, still not 100% but its not 0% either.
