I've been having problems with my card while playing Starcraft. Starts out fine, then around the twenty minute mark it'll just crash. So far my two screens have either A. Turned a different color per screen (see orange and green), B. Just gone black, C. Gone static like a TV without a station.
What is going on? My case has some massive fans in it plus I can hear the GPU fan if it gets going fast and I haven't even heard it.
I'm running Starcraft in OSX, when I go into windows to check it out using Precision X and OC scanner then GPU clock jumps around between 399 and 797, but the temps stay around 61 Celsius.
80 is higher than I would want in a synthetic benchmark, much less a game.
However, it's still "within spec", so maybe your latest game update does have something to do with your symptoms. (Although I would expect a lot of people to experience the same problem if that were the case)
Could dust buildup have anything to do with it? I haven't cleaned it in four months and I live in a really dusty building. Also - the card is a EVGA superclocked version, looking it up its not unheard of for it to get to eighty.
Another question - If I do return it should I send it back to EVGA or to newegg where I bought it.
