Charm being I rma I get a brand spanking new card free of all manufacturing defects.
~1.1v is stock/reference voltage for a 7970? AB is setting/reading the PowerColor card at 0.8v and the system keeps crashing at desktop. It's got the memory at 1.7v which I dropped to 1.5v.
Gonna see if I can get an advanced RMA this time, so done with this stupid card, wish I had sold it the first time I got it back. Have had it since Dec. 2012, it's been dead sitting in a box or with Gigabyte most of the time I've owned it.
