post #35681 of 38737
I7 2600k normally at 4.5ghz, 4.7 for benchmarks. 16 gig of 1600 ram, two reference 7950's, everything under water.

I have bf3 but rarely play it. Haven't reinstalled it since the last time I reformatted my ssd. When I played it I maxed out everything at 5760x1080 and the fps was fine. Don't have in numbers. Just remember it being smooth.

I game at 1150/1600, benchmark at 1285/1800. Takes 1.3 volts to hit that clock and I don't feel comfortable gaming at that voltage. Occasionally I'll game at 1200 or so as it takes a good bit less voltage to hit 1200 than 1285.

I hate to see it go.

Switched the placement of my 7970s and got several hundred points higher in 3dmark11

I am pleased tongue.gif

Resurrecting an old post as I have fallen into this hole too. Only in my case there are two 7970s in crossfire, although xfire doesn't seem to be working properly, a Vishera running at 4.8GHz, and both cards are showing 100% utilization trying to play this old title. I say Xfire isn't working properly because the voltage on the second GPU card is not raised to 1.2V like the primary as reported by MSIA.
Tried adjusting the CAP in Catalyst, but didn't seem to make any difference. An example was to force xfire off completely.
Running the latest beta drivers too.

This is just too embarrassing to contemplate. mad.gif While the game plays fine, the idea these cards have to labor so hard makes no sense to me.

Any suggestions? I'm looking for tweaks to the setup, not turning down options in the game. FWIW, the in game conditions have all options at max, and Vsync turned OFF at 1080p res.
post #35687 of 38737
They are both utilized fully because you have V-sync off.. That's how i play ALL my games although i game at 5760x1080 on two 7950's. If you are getting 100 percent utilization on both cards crossfire is definately working.

post #35688 of 38737
Okay, something else to try. But, I can't explain why the voltage for the second card isn't set correctly, and its temps are nothing like the prime card. Anyhoo, it would be good to solve this problem.
post #35689 of 38737
Well are the temps on the second card lower than the main card? They usually are on air. Nature of the beast. Also lower voltages for the same clock are better. .
post #35690 of 38737
I'll post a screen shot so you can see later. Inexplicable to me.
