    Crossfire   Crimson   DVI = Broken


      Describe your system:

      AMD Graphics Card = 2x Sapphire Vapor-x 7970 GHz Edition


      Operating System = Windows 10 64bit

      Driver version installed = Problem has been tested on every single version of Crimson. No problem is found in any version previous to Crimson

      Display Devices

      #1 - QNIX 27" 1440p 60 Hz via Dual-Link DVI  --- ISSUE PRESENT

      #2 - Acer 24" 1050p 60 Hz via DVI --- ISSUE PRESENT

      #3 - Asus 27" 1080p 60 Hz via DP --- ISSUE NOT PRESENT

      CPU/APU = Intel i5 2500k

      Power Supply Unit  Make, Model & Wattage = 850 watt Sparkle Magna

      RAM = 2x4 GB DDR3 1600MHz



      Describe your issue:

      Older games with crossfire profiles created before Crimson (Witcher 2, Diablo 3, Testament of Sherlock Holmes, Rocket League, etc.) crash on bootup when crossfire is enabled if using a display connected via DVI.


      What works:

      - Updated crossfire profiles (Fallout 4, The Division (though works is a loose term for that one...), etc.

      - Using a DP Port

      - All pre-Crimson Drivers


      What have you tried:

      Uninstalling the drivers

      Reformatting the HDD

      Rolling back to pre-Crimson - THIS WORKS

      Turning of ULPS

      Disabling pretty well every feature that can be

      Trying different resolutions when starting a game

      Trying different resolutions on the monitors

      Playing in windowed mode - This obviously works since crossfire is then disabled

      Trying compatibility mode


      This is NOT an isolated issue. This is a common theme...
