I get some rejects from Decred too, but nothing too bad.
Whats bad is the temps of the cards... Can't run it on 7950's as they go over 80 degrees

Any advice here? tried lowering the clocks to 800Mhz and memory to 1200 Mhz, lowered voltages but still geting too hot...
I switched to dcr.coinmine.pl now getting 0.00% rejects, across 29 cards. suprnova dcr pools seems crap I guess.
I dont mind a few % rejects, its realy a small amount.
The temperatures are the problem, i can get the RX series cards to 70 - 74 degrees, which is not that bad, but the 79xx series just goes 80+ hehe.
Can anyone tell me what the degrees are on 280x cards for istance? Im guessing they overheat to, since its basicly at 7970 repacked.
