Hi everyone my first post here.
I have run a mining rig now for month with two 6990 working fine on Ubuntu 11.04. Now I see a problem with GPU0 with high temp and unstable hash rates but GPU1,2,3 is stable and not running over 100C temp. And also when GPU0 reach 100C clock speed drops to 500Mhz and GPU loads flips between 0 and 100%
Is possible I have overheated one GPU on the card if so how do check this? Or any other tip?
