I have run a MSI afterburner 2.1.0 for a while. I have two 6950s on my rig, watercooled, and with the msiafterburner.cfg unofficial overclock enabled.
For months I have run at 1150MV / 950MHz core / 310MHz memory / fan speed 25% on both cards. They sit nicely in the 40C range (all 3 core sensors), along with the vregs.
Recently, my water pump was overheating and not circulating - causing the cards to overheat a little to the point of shutting down my computer.
Now I can only change the overclock settings of one of the cards, the other shows this weird screen:

I couldn't find a similar screen in Google or on this exchange - so I thought I could make a topic should someone down the road experience the same.
Any suggestions will be appreciated, and I will keep this updated with any solutions.
