    Can't Enable Crossfire on 2x290Xs Since 16.12.2 (Device Manager Code 43)

      LAST WORKING DRIVER w/ CROSSFIRE: 16.12.2

      CROSSFIRE NOT WORKING SINCE: 17.X.X

       

      Issue

      I have not updated this PC's video drivers in a while. Crossfire was working properly throughout all releases in the driver 16.X.X series.  I recently tried upgrading to the latest 17.7.1 and realized there was no option to enable Crossfire under Global or individual game settings (see global-settings.png)

       

      Windows Device manager shows one GPU is not working properly (code 43) and was stopped (see device-manager-code-43.png).

       

      I went back and tried clean installs of various 17.X.X drivers back to 17.1.1 using DDU and AMD Clean Install Utility.

       

      Crossfire works properly again after clean installing 16.X.X drivers.

       

       

      Help is greatly appreciated.  Debugging this has already been a pretty time consuming issue. Please let me know if any additional information is needed.

       

      Thanks,

      Jon
