So I am running 5 gigabyte r9,270s on this board with windows 8.1 and catalyst 13.11 beta 9. The cards are also undervolted to 1.000 and stable. The issue I am having is that gpu 0 is always running 7-8c hotter than all of the rest. My first idea was OK, bad thermal paste so I plugged the card and rebooted. Windows now sees 4 cards, I start mining and boom the new gpu 0 does the same thing. I only pulled 2 cards out in my test but each time I did gpu 0 would move to another slot but would behave the same way. Gpu 1,2,3,4 all run around 68-69c but gpu 0 (no matter which card it is) runs between 75-76c. Also interesting, I excluded the device from config and sgminer sees that its off but still the temps shoot up.
Anyone have any ideas.
Here screenshot of what I am talking about. I haven't test taking more than 2 cards out but so far whatever gpu gets seen in sgminer as gpu0 gets hotter than all of the others.
