Hello,
i have recently bought two Gigabyte HD7850 OC for crossfire replacing my GTX560 SLI. Everything were running fine on NVIDIA so i have replaced graphics, reinstalled Windows and now i cant play any game longer than 15 minutes, PC completely freezes... mostly blackscreen or monitor shut down, all i can do is hard reset. I have fresh Windows, newest drivers, all components are fine and now when i changed my graphics everything is screwed up. Its not doing while IDLE, or watching movie/internet... its just games freezing my PC. I have tried all crossfire settings in Catalyst and none of them helped, one single card seems to run stable so its crossfire. I think Catalyst isnt really ready for crossfire yet, but im sure im not only one having 2 new Radeons and so far i havent find anyone complaining about PC freezing. Also i have read a lot of crossfire reviews with new Radeons and none of them tells anything about complete PC shut downs during tests, maybe some lesser problems but not this insanity i am experiencing. That makes me wonder if one of my graphics is bricked or something else. I really dont know what to do to fix this.
I was pretty happy about performance increase over GTX560 SLI... around 25 FPS increase in most games making decent running games (Battlefield 3, Crysis 2 and such) run perfectly as i wanted... the performance is exactly where i need it, watt eating is almost at half compared to GTX560, IDLE 3W technology is awesome.... but... this freezing just freaks me out and im hopeless. I was using GTX460 SLI, GTX560 SLI without problems or stuttering in games most ppl encountering and was pretty happy about 2 graphics setup, never had a single problem with it. Now with new cards this problem appears and i have very bad feelings.
Some important info:
I have CPU on default clock with turbo boost which is 3.8Ghz, memory freq set to auto which is 1300Mhz, newest ASUS bios for my MB, temeratures are fine on all components, PSU is more than enough...750W for new less eating graphics. I have tried both crossfire cables just to be sure, i know if it was cable crossfire couldnt work, but you never know.
Anyone got any idea what could go wrong there?
