Garret, I have exactly the same issue - running the artifact scan in ati tool shows a few little yellow dots (3 or 4). However, they are not detected as artifacts and i've not had any problems in any other benchmarks. If I drop my core clock down to sub 350mhz they don't appear, the higher over 350 I go the sooner they appear (it takes an hour at 600mhz for the dots to appear). Then again my GTO has a very poor core - I can only do 665mhz without it eventually overheating and artifacting / crashing. Messed about with the delta in bios and its not that - infact i've changed my delta to 75 for 650/650/725. Core temp gets to 67c after 30 mins and stays there. I think Im getting poor core contact, but can't risk taking the heatsink off incase I rip those memory pads..have nothing to replace them with. Memory is happy at 851mhz, so I've lucked out there though. From what I saw of the core oc increase in scores though I'd much rather have the ram clock well than the core. Course, both would be nice .

Matt.
