I've been running 2 Sapphire 6950s in xfire for sometime first with a clean install of the 12a drivers then with the 11.1 beta. I did flash my cards bios with the "Unlocked Sapphire file" before installing the 11.1 drivers.
I have been using TRIXX to overclock to 880/1325 which should be safe.
The other night I tried to go back to the 12a drivers because TRIXX worked better with them than the 11a. I did the driver uninstall booted in safe mode ran Driver Sweeper rebooted and tried to install the 12a drivers. The Drivers would not install correctly. I repeated the uninstall process and in safe mode even uninstalled the video adapter.
I have tried with both cards, a single card and have swapped my 2 cards around and no luck.
I also tried to go back to the 11.1 drivers and have the same issue. The Drivers fail to install.
I keep getting these errors -
