I'm running into some trouble. At this moment I am running on 1 of 4 VPU's which is very frustrating. I've done some searching and tried setting up a chain and enabling it, but all I get is an error saying the platform is not supported. When I reboot, and check the Crossfire status, it is disabled.
There is a message saying it could be enabled via P2P and GART so I did some more googling and found nothing about it.
