My GB GTX670 OC overclocking info:
Stock Core Clock after 'Kepler Boost:': 1189MHz
(Apparently) Stable Overclocks So Far (lots of benches run w/o crashes/artifacts)
1) 1345c/3225m (1.162V)
2) 1325c/3600m (1.162V)
The frequencies are all actual 'observed' clocks via AB graphs during bench runs.
Drivers: 301.25
Max Voltage can be raised to 1.175 in Precision X, but won't budge over 1.162 in AB even w/voltage slider maxed. I've NOT tried OC'ing at 1.175V yet but plan to try it out in the future.
I'm also going to be running various benches to determine which of the two OC configs I prefer ... but I'm very much leaning towards the 2nd one as the better of the two. It seems worth it to lose a little core to gain a ton of memory bandwidth.
At these clocks, my temps get up to 62-65C after running for long periods at 99%.
I don't know what the fan speed is (my guess is the 45% range) but I'll tell you this ... my case runs VERY quiet as all my fans are on controllers ... and I absolutely cannot hear the card at ALL ... even after 20 minutes of benching Heaven maxed out. Not even thinking of making any fan profile, the one that's on there now works perfect.
I'd guess that at 1.175V it might be a little different but I'm pretty damn happy what this card does, in terms of noise, clocks, and temps at 1.162V so I doubt I'll push it any further, at least not for 24/7 use ...
