2x 6970 cf ati display stop responding and has recovered[fixed!]!

post #1 of 2
Thread Starter 
So I traded this guy my 6990 which worked flawless for 2x 6970 straight trade. I was alright one sweet deal. Put it on installing 11.10 preview 3 drivers and all of sudden keep getting ati display stop responding... At first it was doing it while right after the windows logo and when it would start a game. I would sometimes get a bsod about atimpeg or something like that and had to reset. Tried all types driver combinations and didnt really make it stable. Now here what I analyzed. I did the windows experience assessment and it would stop responding but after it resets itself, it would work. So while its doing the assessment I tried to do furmark and voila it worked! Complete stable for hours. So I started thinking its graphics hardware at fault. Thinking about what I did with my cpu overclocking and how it being stable, I though about voltage. I was thinking going from 2d which is the desktop to 3d would be crashing due to something. Then I started researching that ati would have power saving features that would downclock cpu core, memory core, and Voltage. I remembered in the guide about overclocking from this forum having drastic voltage change may cause instability. After days of researching on forums, I found this guide on a forum that creates ati profile that raises core and memory at idle, which makes the voltage jump from 2d and 3d a lot smaller.

My settings now are clock at 400mhz core/900mhz memory at idle

Now it is working rock stable. Without all these guides on this forum, I would have never be able to completely troubleshoot these cards. Thanks to ocn, I am ready to go bf3!
