My 7950 has around 270 h/s but it stops about an hour - 2 hours into mining. No errors pop up, the hashrate just goes down to 0 suddenly. All stock settings with catalyst 13.12.
yea around the same time on mine as well. both my multicard rigs dropped 1 card each since my last post. really need to get it look into as to why it drops 1 card from multicard rigs, somewhat fustrateing.....
