    Old thread I know, but two things I did to get my Crossfire to work were:
    Disable IOMMU in BIOS (North Bridge settings, I think) and;
    Change the Crossfire cable position on my 2 7970's - I first had it on the inner two connectors but then tried it on the outer connectors and my Crossfire settings started working (and saving after a reboot).

    Hope that helps someone out there!

      On which distro?
      Which version of Catalyst?
      Which games / apps did you test?
      What is IOMMU?
