they dont. mine has never fully recovered after a crash.
when i crashed in heaven, i restarted or my scores were nowhere near what that shouldve been. ive seen others say the same thing, "restart to fully recover the drivers"

when i crashed in the heaven bench it would reset the clocks to the factory settings but not to the OC settings i had before...is that what you mean by "fully recover"? cos all i do is just re-apply the profile and the clocks are back.

nope. never worked for me. drivers straight up crashed and never fully recovered. its possible every card and driver combination is different. quite possible seeing every crd is different. dunno

With my stock card (EVGA FTW version, all clocks at +0 modifiers, voltage is automatic, etc), in Heaven DX11, maxed out, at 1920x1188 (16:10, 1188to account for the windowed setting), I'm getting a score of 1117 (Average FPS: 44.3). I don't think this is very good, but I'm not really sure.
Another thing, I see people setting their core clocks to very high values (~+160 or more) and getting stability. Mine crashes at clocks as low as +50. Can anyone explain to me why this happens? Is it because my card is the 'factory overclocked version', meaning that even though the core clock is at +0, it would be at +50 (example) on a non factory overclocked card?
Or Is the difference in stability really because of my specific GTX 670? I'm using an RV02-E case and the max temperature usually floats around 75-76 celsius on a full load. It idles at 27-28 celsius.
It's a little bit difficult to find a place of comparison when you're using a 16:10 monitor in a world of 1080p. I know that those extra pixels do make a difference. I'm almost considering trying to return it and getting a gigabyte version for the additional cooling... Or maybe I should just pick up an aftermarket cooling shell for the card instead...
update: I'm maxing out at about a score of 1187 or so (47 FPS average) in heaven DX11 at 1920x1188. with +35 core and +200 mem. Still have a lot of tinkering to do between the core and memory clocks.

You know, you can run 1920x1080 on your monitor for testing purposes thumb.gif

Why don't you see what you get using the settings specified on my Heaven bench thread here. Have a look at what others get, what their clocks are, etc.

Also, check the first link in my signature ... basically your understanding is correct, a factory OC'd card is likely to be able to run a lower +core offset value, cause you're starting out higher in the first place. However, the max boost your card will reach (which is what matters, and is how to properly compare different cards, not via offset which is practically meaningless) is a 'lottery' for the most part.

Thanks for your response. I tried using the 1920x1080 resolution in fullscreen instead and got 1248 at +40 core +200 memory. Judging from the thread, that's not a bad score at all so I guess I don't need to worry too much, I still have a lot of testing to go since I think I've gotten my core up to +60 while being stable.

Thanks for linking your thread!

And thanks to the other guy for his suggestions, I maxed the voltage and increased the power target.

Trial 1
100% power target
+40 Core Mhz
+200 Memory Mhz
----
Score: 1248

Trial 2
120% power target
+50 Core Mhz
+200 Memory Mhz
----
Score: 1282

Trial 3
120% power target
+55 Core Mhz
+250 Memory Mhz
----
Score: 1293

My GTX 670 blocks arrived in the mail today. Quite a bit of modding ahead of me, don't think I'll be able to get them in for a few days. Hopefully I get some very nice temps as the only thing annoying me with the OCing at the moment is my top card jumping over 70C all the time.

Card Model: EVGA FTW
OC Software: Precision X
Max Core Clock: 1275
Max Memory: 1822.5


PROOF (3DMark, GPU-Z, etc.):
http://3dmark.com/3dm11/3842558
http://www.techpowerup.com/gpuz/923ep/

I found that setting a slightly more aggressive fan curve helped me bump the memory overclock substantially.

Also, I am able to validate with the core clock about 15MHz higher, but it will crash after 1-2 hours of continuously running Heaven. This level seems stable for 24/7. Other notes: using an H100 for cooling, and I have 5 additional case fans, which might be helping keep temps low - I never get above 63C.
