After discovering my 670's memory will quite happily overclock to 7GHz (1725 actual clock) which has improved performance in the few games I've tested so far. I'm just wondering what kind of overclocks others are getting out of their 670's.
I have seen some that seem to run 500MHz over this within the 3Dmark results page but I'm not sure if they were clocked purely for benchmarking or if they run that speed all the time for gaming.
I've tested my overclock with Sisoft Sandra's Vram latency and it seems they must increase the timings to get the cards to clock this far but the gaming results speak for themselves. Arkham City averages at 60fps with Physx and 16xQ AA. Before it was closer to 55.
For the record the max the GPU seems to want to go to is 1163. no matter what minimum voltage I throw at it, It generally seems to work at 1.175 anyway, sometimes clocking down a notch for some reason.
I've had to set the minimum voltage to 1.012 in order to get Tomb Raider to not glitch in one or 2 places.
I've set the fans so that they keep the card under 70c no matter what, and it's not too noisy. Can't hear it over general gameplay.
Generally the drivers report that the operating voltage and the reliability of that voltage are what's keeping the GPU at 1163.
Has anyone unlocked the max voltage and what would be your experience of it if you have?
