What's your stock voltage? What voltage do you need to hit 1100?

Curious if higher voltage is dangerous despite low temps? (Such as is the case with CPU's). At 1225 core and 1.3v in AB my 7970s only hit about 60c core and 55c vrms. Temps are fine so I was thinking of switching to trixx to go to 1.4v but not sure if thats safe.

I'm still on 12.4, and I know 12.8 is out now. I'm wondering if there have been any noticeable optimization between these driver releases for GW2? I know on 12.4 GW2 wasn't even out yet.

I'm having an issue with my card that I would like to get some guidance. I've used 12.7, 12.8 and even 12.9 and each time i leave just my desktop up, my GPU usage will ease up to 100% and my 3d clocks kick in. I'm using the current AB with the -xcl command to unlock the unofficial overclock mode. What would cause this?

Your sentence there contradicts the process. You're either confusing the terminology or are doing it wrong or both? I suspect you're at least doing it wrong? I've written a how to for either method that you can double check the steps you used to enable whichever method you're actually using. Remember, one or the other not both.

I haven't changed voltage at all - just set power level all the way to +20

I will check it out when I get home. I'm rusty in the gpu overclock department since my last card was a x850xt lol. I know I did the -xcl method, just can't remember if I followed the directions or if I just did it real quick and jumped in to overclocking.

I easily have the card at 1125/1575 without ever touching the voltage. The stock fan profile keeps my card at 75C max so I think its fine.

As for benches, heres some with sliders in CCC maxed, stock voltage.
