    no crossfire options for R9 280X

    ghettohead

      Hi All,

       

      Having problems setting up crossfire. Been looking through forums but no solutions yet.

      I have a Sapphire 4GB R9 280X and a MSi 3GB R9 280X Twin Frozr.


      I have done clean installs of drivers and software. Swapped cards over PCIE16X lanes.

      Disabling and enabling.

      Connect bridge both ways round

      No settings in BIOS that relate to crossfire.

       

      There are no options showing in Radeon nor in Catalyst Interfaces to enable cross fire.

      My MSi is showing 'Primary'' and Sapphire showing as 'Disabled'.

      However both operate normally when plugged into monitor and controllable from Radeon software
