On the brink of dispair. 2x sapphire 7870xt boost crossfire will not work properly

Hello everybody!

I am having huge problems with my crossfire setup. The short story: One of my cards was constantly throttling under load. Both core clocks and GPU load were highly irregular and all over the place. After i turned of ULPS and powerplay via MSI afterburner this problem was solved and i got between 95 and 100 % load continously in Heaven benchmark. Happy me smile.gif

But in Battlefield 3 i get between 50 and 85 % load on both cards. It never reaches around 90/95%. This results in having 50 to 60 fps in some maps and area's. This should be higher on ultra with 2x msaa.

I have tried everything last couple of weeks. Clean install, new drivers, nothing seems to work.

I am on the 13.4 drivers since the last beta drivers give me BSOD's when i turn of powerplay and ULPS.

I think the whole thing has something to do with the fact that these are "boost" cards. Any way to turn that off?
