Here's the line from GPU-Z where the GPU got the hottest (I ran Heaven for a good few minutes and didn't see any problems). I'll probably try bumping up more using Heaven as my benchmarking tool since Kombustor is showing me artifacts at any speed (I think it's the XP driver).

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 ...

does the voltage slider actually work on the gigabytes?

oh and btw, I highly doubt you'll be able to step up to a 680 classified....step up is only reference model.

Yeah I noticed that on the website. Kinda sucks. My old gtx570 SC came with the lifetime warranty, I don't understand why the 670's don't. I may go ahead and get the warranty and step up to the 680, I was really hoping to stay above 60fps in BF3 with this card frown.gif

On a side note, Has anyone else noticed the fan on the EVGA 670 has a very high pitched whine when cranked up?

EVGA has a new warranty system on all their cards....the main benefit is the 3 year transferable warranty

Also, I'm reading multiple sites showing 60fps with the 670 at 1080p in BF3...

I want to see some scores on 1330 or something like that, 3d11..
Non TOP versions will OC better than TOP, trust me Ive seen it before on Asus GPUs..
p1010815.jpg
That 580 needs 980mhz to be on pair with stock 670. Faster in some games, slower in others..

I got a whole mess-ton of benchies for ya right here ... join the fun smile.gif

The only thing it does is that if I max it at 1.175 in Precision, the card will actually jump up to 1.175. With Afterburner, the slider does NOTHING, and my card won't crack 1.162V.

Yeah I read the same things and that's ultimately why I bought the card but I think most sites used the single player to test and I'm seeing dips below 60 in multiplayer. It still performs very well, it never goes below 50fps but I was just hoping to have nothing less than 60 constant.

My settings for reference: 1080p / Ultra settings / 4xAA / 16xAF / No FXAA / No Motion blur / HBAO. I also have some quality options in the nvidia control panel like transparency aa 2x supersample.

I could easily get above 60fps constant with some tweaking but I want all the eye candy goodness.

I'm working on OC'ing my card, I have an EVGA vanilla model. I've noticed something weird from the start, I mentioned in the 670 official owners thread. My vanilla model runs at 915mhz core and 1084mhz boost straight out of the box, where the specs say it should only be 980mhz boost. The 1084mhz boost is shown on the FTW model. Has anyone else noticed this?

Anyways, the card so far seems to only want to do 1215mhz, +135 core and +300 memory. I can probably push the memory more but the core aboslutely will not do +140 at least on air. It runs pretty cool with a fan profile, I will try to post some validated results tomorrow once I play with it some more.

Has anyone noticed it? Um ... Pretty much everyone. Welcome to the party wink.gif

I'm trying to coin a phrase for it, calling it the "Kepler Boost" just so people can have a common, simple phrase to refer to the phenomenon.

My Kepler Boost is 130 ... meaning that whatever I set my clocks to according to AB or whatever, using the offset, my actual operating core frequency will be 130MHz faster than that value.

So 'stock' the Boost clock is 1059, but when I actually run something, the core clock will be at 1189. And that extra 130 boost is constant, at least for me.

Right now I'm running:
1059 (stock boost clock) + 178 GPU Offset in Precision = 1237 (in GPU-Z) + Kepler Boost (130) = 1367MHz
