They always worked fine except in BF3, where I keep getting BSOD's while having crossfire enabled.
The other day I exchanged positions in a last try to get it working and with the newer driver(12.4) I gained voltage control through Sapphire Trixx only and voltage monitoring through GPU-Z.
So I started doing OC'ed runs on Uningine 3.0, OCCT, Furmark, other games I play.
After doing all of this I was getting optimist cause I didnt get a BSOD and they were stable, without voltage adjustments I managed to get 900/1100 @1.150 and keeping temps under 65 with auto fan.
Decided to give BF3 a go, after 20min's with temps arround 56ºC BSOD(This was at stock settings
I turn off crossfire and use my newer revision card as my main GPU and it gives me no problems running BF3, I basicly only get BSOD's on BF3 while using crossfire and Im getting tired.
Every benchmark I run, it doesnt give me a bsod runs stable even with a minor overclock on them, I try to run BF3 at stock and I get a bsod.
Any1 had/has similar problems?
