ok learn something new today. Doesn't it at least improve stability on overclocks with the slider up?

Nope. Normally it allows you to overvolt the GPU core, resulting in better overclockability, but since nearly all 6xx series cards have their voltage locked, it doesn't matter what you do with the slider; it simply has no effect. You might be able to use it to undervolt your card if you're into that, I never tried, but you can't raise the voltage even a single millivolt over stock.

The stock on my 670 is .987, max is 1.175. My Precision monitor shows the current voltage at 1.175 if I raise it and .987 if I reset it.
Are you saying it is always at 1.175 regardless of what the Precision monitor is showing?

edit: just ran a quick bench and you're right. The slider doesn't do anything! It will still hit 1.175 when benching regardless of where I set the slider at. Just never paid attention to it till now.

I have the same card and mine NEVER reaches that temp. At least not during game play or Heaven. Furmark is a different story.

Now I have a mostly stock fan profile, however I have mine set to jack up at 65C so that throttling doesn't happen, but that doesn't happen for me ever.

Now, for me, I have my card clocked to +60 core, +400 mem, and +145% PT. I get 49FPS in heaven benchies maxed out.

The card comes with PrecisionX and i highly recommend it. That is why I went with this card over a vanilla 680; for the brand and OC program.

I didn't get to read everything yet, but I wanted to note one thing. I WAS using PrecisionX but lastnight switch to Afterburner because of the overlay I can put on Tera while running it, I think my entire profile switched over except my fan settings. I will read everything after Nexus on Tera and go from there smile.gif

That is what it was, the fan settings weren't saved for Afterburner. Is there any type of overlay I can get so that I don't need to run afterburner?

Here is the temp right now during Nexus.

Ok, I think I fixed it, I found the on screen display that I needed in Precisionx and went back to that, much better smile.gif.

So at this point there is nothing I can do to improve my overclock correct?

I was told that overclocking the mem has a much better effect then overclocking the core itself. I would up your mem offset to +400, which will put your memory at 7.0 GHz. I would be willing to bet that you could probably raise your core another 20 or so Hz. Those will at least get you in the 1200 range, but that is where your card should be.

Whether OC'ing the memory or the core has the 'greater' effect has a lot to do w/the specific test you're running, where the bottleneck lies in that particular scenario. Is it bandwidth, or is more on the 'mathematical processing' side of things?

Heaven, esp. with maxed AA, is pretty bandwidth sensitive, so a memory OC really helps (a core OC does as well, though). 3dMark11 otoh is mostly about the core speed.
