As most of you know the hd5970 is a dual gpu card and relies on a internal crossfire chip. My problem is the in radeon settings version 16.1.1 says that one of the gpus are disabled and crossfire is not a option. In gpu-z it states that crossfire is disabled and the pcie slot speed is x16@x1 2.0 on the disabled gpu. I have tried other drivers that say work with windows 10 but haven't tried anything older. I have tried re-flashing the bios on both gpus. Any ideas would be appreciated, thanks.
