whats your vcore's for these cards?
Stock. I never use windows, so can't touch the voltages on Hawaii chips yet.
got 5 pieces.
one is going dead on stock (gpu0) trying on lower gpu speed (now 900 , stock 1000 ) at 1000 is going dead after few seconds - probably I dl RMA.
Mem clock lowered 1300->1250
cooling is same for all - but temps are weird high.
Seems like they had been assembled in rush!
Not exactly uncommon - you could RMA it, but is it worth a 10% hashrate boost to lose time waiting for a replacement? Have you tried 947 engine?
You can re-thermal paste the cards if you don't mind losing your warranty, and it might help even things out while shedding a few degrees. I have also observed some cards that read at higher temperatures but don't actually seem to be (e.g. the measurement seems skewed). As long as they are within range, I wouldn't be too concerned.
I do agree they seem like they were assembled in a bit of a rush. But not as bad as the new MSI 290 cards... those are bloody weird, but good hashers anyway.
