Card is not modified, drivers are at default (Overdrive enabled but clocks at default).
Here the Afterburner 160 monitoring during and after Crysis Warhead x64 DX10 Enthusiast 1920x1200:
After quitting the game, one core keeps stuck in 3D clocks. Afterburner / GPU-Z fail to read correctly with these drivers?
See comment by W1zzard and erocker at tpforums
Also according to CCC though: after quitting Crysis Warhead back on desktop, according to Afterburner 160, GPU 1 stays in 3D mode 750/900 Mhz while GPU 2 switches to 507/500. According to CCC it's the other way around: GPU 2 stays in 3D mode 750/900 Mhz while GPU 1 switches to 507/500....
How to tell which one is accurate... maybe both measurements are false... in the end, what counts is how do the games run, answer is: seemed nothing out of the ordinary sofar. DX9/DX10.
It's not only ULPS i guess, because on 4870X2/Vista x64, the registry shows it isn't even enabled... Afterburner and GPU-Z are not compatible with these drivers.
Still, also tested 3DM06 freshly installed from the CD.
My E8400 runs @ 3.84 Ghz, both Vista and Futuremark read wrongly because they don't understand the 8.5 multiplier...
Result:
The GPU usage isn't equal.
Is that too low? (don't forget that is a Vista system, and the card runs @ stock clocks)
