Two 6950 on Crossfire, With diferent Bios

post #1 of 5
Thread Starter 
Hello lads...

Well since I got my 2nd 6950 card I started to have some flaws and seldome crashes on games... Which became more often to the point it was annoying. So I took the time to investigate what would be the problem. I troubleshooted both cards in single mode and they work find. The problem is just when they are running crossfire. The crashes are totaly random. I can play BF3 for hours withou a problem, exit the game, enter again and crashes as soon as I enter the map. I have installed all kinds of drivers and caps (Yes, I do uninstall them fully before installing a newer) and the problem is still there.

But... this morning I was OCing my CPU and opened CPU-Z and for no real reason I went to the GPU tab and saw that there was no information on the cards. Only the model and the VRam. So I became curious why it didn't show anything. After that I just downloaded GPU-z and found out that my cards have diferent BIOS as you can see:


Card one



Card Two



Btw, Crossfire was disabled when I took the pics. But its always enabled. biggrin.gif


This makes me wonder if the different Bios is the issue here.... Does anyone one if it could be the problem?

Thanks a lot!

I wouldn't think so since it appears they are matching cards. I mixed a reference card and a non reference card and didn't get the issues you're describing. Are your cards unlocked? I would say that's the issue if they are. My cards were much more stable when I didn't use the 6970 bios.

Nop, they are not unlocked. I did once tried to unlock my first card, but .. well... went bad but I managed to flash it back to the Bios it now has. Didn't tried to flash cards again. The 2nd one has the original, Factory Bios, I belive.

Are these cards reference or non-reference?
