Granted I can't quite confirm it's at 1.2 seeing as how my dmm needs a new battery, but I do notice that I can clock slightly higher and the temps correlate.

Right now it's running said demo at 714/1000 and finally seems stable. Fan is at 70% with the core temp at ~72c.

I don't see it being worth it at this point. Maybe I got a moot clocking card. Unless I'm drastically overlooking something here. The card is a Sapphire, if it means anything.
Yeah, I have flashed and re-flashed with different voltages and my Visiontek 4850 seems to top out around 700 anyway so I just use CCC Overdrive and keep it at 700/1133, Oh, I did flash to the Asus BIOS that was floating around early on and the auto fan speed control with SmartDoctor workls nice... 1.16v, 700MHz is it for me... done tweaking for now until I get an aftermarket cooler....
