Are you overclocking ?

No, using stock cards.

Anyone else have a 'GPU #0 returned incorrect data!' error? Happens on GPU #0, 1 of my 4 Saphhire R9 280xs, after about 6 hours of mining. It's always the same GPU returning the error, while the others are fine.

Had such happiness with one card. In my case, solution was a significant drop in temperature. Probably some radio elements lost characteristics with age and at high temperature becomes unstable.

What temps did you have before/after? My GPUs are hashing at around 68-74 C.

what are your command line in the miner &?
