Anyone know if it's safe to up the voltage on these things? Mine goes to 1.175 and I wasn't sure if it was ok to go a little higher.

Confirmed by Jacob at EVGA that 1.175v is max specs.

If its safe to go any higher I'm not willing to find out. There might be a voltage limiter.

I updated my original post to state that I started using the 2x 680 inside the core (just near the end), which is when the crashes started. I used my 560 sli up 'til then and never had any issues in the game, so it is an issue with the 680's drivers or something.

Also with your 680 sli's can you do some testing for me?
  1. Can you up the CPU frequency to lets say 5.0ghz and run 3dmark 11 Performance setting in SLI with your stable OC ?
  2. Heaven 2.5 > 1920x1080 8xAA fullscreen, Extreme TESS and everything maxed?
  3. 3D mark Vantage run please
Will appreciate this heaps, and i will base my purchase pretty much of these results mate thnx

I crashed on heaven 3.0 for some reason, I think I have to reinstall because I wasn't crashing on higher clocks yesterday.

I hate the whole power % thing. My results are never consistent. Sometimes my power percent goes above 100% and I do a good benchmark, and then sometimes it starts dropping down to the 80s and I get a crap result. I don't like overclocking on these cards at all.

You can set targets and clocks all you want, but it never really stays there like the 5xx and 4xx series did.

I installed the EVGA High Flow Bracket sent to me for free from EVGA. Noticing it does bring down 1C temps idle and 2C temps full throttle than before.

The hot air being able to exhaust quicker does help. Same went for the GTX 580 I had it installed on.

I know exactly what you mean in that regards. We are not sure how the 'inner' working on the dynamic over clocking is working. Once we can figure out how it operates we can adjust accordingly. I feel confident that Nvidia is going to improve this feature with drivers.

Here is an example where I had a mild over clock on my card running EVGA OC Scanner X with a 100Mhz bump on Core and Memory.

Now maybe I'm just reading it wrong because GPU Boost is working behind the scenes and I just don't know it. Example is when I run EVGA OC Scanner X 2.0.0 and see the following log text:


2012/03/31 @ 00:04:39 >> - GPU 1: NVIDIA GeForce GTX 680

2012/03/31 @ 00:04:39 >> - PState 2 - GPU clock: 705MHz - Memory clock: 3004MHz - Shader clock: 1411MHz - GPU voltage: 0.987V

2012/03/31 @ 00:04:39 >> - PState 8 - GPU clock: 324MHz - Memory clock: 324MHz - Shader clock: 648MHz - GPU voltage: 0.987V
2012/03/31 @ 00:04:39 >> - Fan speed: 34%

Is the card actually being boosted or not? Says my GPU Clock is 705 Mhz? Shouldn't that be at the very least 1006 Mhz? wth.gif

I realize that if in some particular instances where higher clocks are not required to run it will down clock and if it's not hindering us then that's not a problem.

What I've found is that even though I had got through a +140 Clock +400 Memory bench before in 3DMark11 score I actually ending up beating it with a lower +100 Core +200 Memory just recenttly at 3DMark11 Score 9521

Either way it's hard to complain much regarding it's performance because it's better and much more noticable than my 580 by 2200 points on 3DMark11 for me. Will still make a great 3D Vision system. I'm about to test 3D Vision gaming next week but can tell from primarily 2D FPS it's going to be great.

I'm about to build a second rig with an IVY / Z77 combo and will temporarily be using the 680 in the interim until my budget allows next gen 780 GK110 or 8970. Speaking of which now to get back to the black NZXT Phantom 410 case and install the white fans I just received along with my Corsair AX850 PSU. Getting ready for April release and test out true native PCIe 3.0 performance on the 680. thumb.gif

Seems to me like it does what it wants. Most of the time I get good results with my OC. But sometimes it will just throttle the power when it should be using a lot more.

After reading that, it makes me really regret purchasing this card. Knowing that my OC is limited by a temp monitor is pretty stupid. I tried what he was talking about and i see where it drops the card down as soon as I hit 70c.
