whats your vcore's for these cards?
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!
