So I'm under the impression I was sold a defective card on eBay but it could be an issue I don't know about. I was going to use this in a crossfire setup but even alone ATI drivers are crashing constantly(crashed under PCI Render test in GPU-Z, CS:GO, Starcraft 2). It looks permanently clocked at 1150/1500 which is the boost clock as far as I know. All my other 280x and 7970s are running fine. The vbios looks to be stock. Using 14.7 drivers. Any help would be appreciated.
