I was, up until recently, happily running 2 x Asus Radeon 7850 in crossfire on an Asus P8Z68-V LX motherboard. Then BF4 told me I should install the latest drivers which I did.
After installing the latest drivers I ran 3DMark to see if there were any performance improvements. I then found out that only one of my 7850's was being utilised. I went to check AMD Catalyst and could not find the Crossfire option which was previously available.
I have tried to solve this issue numerous ways but the most thorough method is as follows;-
1. Upgraded motherboard BIOS to latest version = 4105
2. Uninstalled all the AMD graphics drivers using Driver Fusion. I have also tried Display Driver Uninstaller (DDU).
3. Re-installed AMD Catalyst 14.2 (Still the latest version). I have also tried Catalyst 14.1 as well as the non beta 13.12.
Basically if I use any version of Catalyst above 13.9 I cannot enable Crossfire. Whenever I have attempted to change drivers I have always used driver removal software. My last change was removing 14.2 and re-installing 13.9.
I now have Crossfire but I am missing out on features such as Mantle.
Can anyone please help. It is very frustrating.
