Strange issue that started a few days ago. I mine all night and at some point through the night, one client/card stops mining. It stays on the shot where it's generating xxxmh/s and shows the shares and rejected but does not update. On the pool side, I only see half of the mh/s I normally get so I know the card is not working.
All settings are the same as they've always been, just started a few days ago and has been fine for weeks.
Any ideas?
1040/300 is the clock. xfx 5830
1040 is quite overclocked for a 5830. The most ive been able to get out of a 5830 is 1020, with some not being able to stay stable unless they are at 950 or less.
