I don't know if he got an answer from anyone. All I will say is that I DID once have an issue with AB not allowing me to OC at all, and while I'm not saying it's an identical issue, the solution was wiping both the driver and AB and installing in a different order. I'm not saying, "do this, it will work". I'm saying that the solution, because of how finicky these programs apparently are, is liable to be something annoyingly specific. I would probably suggest a full wipe as an option, but I don't know what else you would need.
Did this just start for you? Has it been going on the entire time?

Well, I did a little bit of tinkering with AB versions and what not and it turns out that the culprit wasn't Beta 14 but rather enabling Unofficial Overclocking. In both Betas 12 and 14 as soon as I enabled Unofficial OC'ing and altered my voltages my idle measurements jumped from .806 to .949. I'm completely alright with staying at 1125/1575 at the moment anyway, so it's no big deal.

On the driver issue, which has been discussed so much recently, I think it will be really interesting to see what happens over the next month or two. With so many games coming out between now and say June-July, AMD really can't afford to have Kepler banging around, while still offering such sub-par driver support. I like the card, and I think it does everything I want it to do, runs quiet, runs cool, and whatnot, but you can't tell someone who pays 1-3k for a top of the line computer rig just to play the new shooter or new whatever that their game will be supported a month after release.
Part of me wonders if this has something to do with both PS3 and 360 running on such old graphics hardware. I can't help but feel that if these consoles ran on newer, more relevant chips, we'd probably see dev kits that inherently dealt with compatibility issues better.

Yeah it seems like consoles are holding the pc back. That really annoys me because pc hardware could run so much better.

My card also only have four screws, as far i noticed.

The chip cooling is great, VRMs not so. My cooler looked properly screwed down (Chip hit 58C on 50% fan) and the VRMs hit 95C (last time I looked) and then went too high and burnt. I'd be interested to know what kind of VRM temps he is seeing on the 7950.

VRM temps after one loop of heaven 2.0 are 60C.

Damn, must only be the 7970 DCUII that has issues. I just want to game!

Could anyone tell me please whats the highest safe voltage for the 7970 ? I got mines @ 1215/1650 with 1.17v (Accelero 7970) but i think i can easily get it to 1250+.
post #5779 of 38701
the actual cap is 1.3v, but you're going to be hard pressed to justify pushing it that far. Temp issues and artifacts are probably going to be seen in the 1.25-1.27 range. As has been discussed here in the last few pages, if you do bump far past 1.2, download HWinfo64, and keep an eye on your VRM temps, as most conventional temperature monitoring programs don't show you that, and it could be the determining factor of whether or not you're pushing too far.

I'd worry more about temp/artifacts during stress tests at full load than I would about voltage if you're sub 1.27.
 
Thanks Geritol!

The card is capped at 1.3v, and people have been using 1.3v under water I think... You'd hit temperature max long before you hit vmax running on an air cooler. Just watch your VRM temps and if they get to 85ish or more stop there.
