Hello,
I've had my computer for about a year now and have 2 6950 graffics cards crossfired. I have had no issues but a few days ago when in Iracing (a racing simulator) my tripple monitor display started cutting out for a few seconds and then coming back on. I assumed the video cards had become loose or something so I shut the computer down, put some pressure on teh cards to ensure they were secure and started the computer up again. When I started the simulator up again I instantly noticed that instead of my usual 144 FPS, I was only getting between 30 and 40 FPS.
I tried shutting the computer down, disabling crossfire and re-enabling it to ensure both cards were being recognized, making sure the fans on both were spinning, re-installing the catalyst software and drivers, etc.... but no matter what I do, I coudn't get my usual FPS back.
After all of this, I decided to disable crossfire and give it a shot (since Iracing doesn't utilize crossfire). Upon startup I instantly got my 144 FPS back. My question now is what could be causing the huge drop in FPS when I have crossfire enabled? Did the 2nd card die? I figured it wouldn't even recognize it if it did. And what would have caused it to just die like that?
For now, everything works great but I'm only using 1 card and if I enable the other I get this crazy FPS drop. Could it be a driver issue (already re-installled them), some setting that mighit have changed by itself?
I have no Idea. If anyone could shed some light on this it would be great. I've already checked with other Iracing users and they still run crossfire so it's not a software change on the Iracing side. I just hope my 2nd card isn't shot because I don't feel like spending the money to replace it when I haven't really worked it that hard to begin with. Battlefield 3 is the only game that really works the card and I don't use it that often. I guess I should test the crossfire on that now but I don't want to dammage anything in doing so if there is an issue with the presumably only good card.
Thanks in advance.
Dustin
