[quotemsg=12016696,0,1308495][quotemsg=12016657,0,642538]You got the same exact card back or a different card but the same model? What about trying it in a different computer? [/quotemsg]
They sent me a new 7970, and I put it in my brother computer And fired up BF4 and it is running fine
SOMETIMES... I my 7970 randomly has a jump in voltage to max(1594Mv). It happens if I have my PC running for days, or if one of my OCing programs conflict with other applications. I'd say remove your OCing apps then download the Beta 9.4 drivers for the R9 Series and see if that fixes your probs.
