Hmm, interesting. I did run across that AMD thread when I ran into a similar problem with my 5970. The system blue screened while I was trying to load a youtube video from within facebook. At the time I was running 11.2. What I did was run driver cleaner and install 11.3 after and update flash, turn off gpu acceleration - so far no crashes. Not sure if it was 11.3 that fixed it or what, but I do think this problem can happen with 5970 too. Has anyone else had this with the 5970 or am I the only one? (win 7 64)
I was using a 5970 until I got this 6990 on Monday, and I upgraded my drivers every month, through 11.3, on Win 7 64. No crashes. The only problem I had (which started long ago) was that with GPU acceleration turned on in Flash, the image on my second monitor would jump up momentarily when a video started (actually not the entire image; there would be a black bar about 1/4 of the way up the screen about 50 pixels tall, and the image above that bar would jump up and back down). Other people had the same problem. I simply turned off GPU acceleration months ago and forgot about it.
Edit: The 6990 does not have that problem, which is nice.
I see. So the crash was most likely caused by something else and not necessarily related to this issue the 6990s are having. I was messing around with the mem clock and fan speed very frequently before the system blue screened. I had the fan locked at 60% and I kept on lowering and raising and lowering the mem clock - trying to find if lowering mem clock affected hashing performance and if there is a "sweet spot" .
But anyways, I hope AMD comes out with a fix, and most of all I hope it's not something that is hardware related.
