So I have two HD 7850 running on an Asus P8P67 WHO USED TO WORK ON CROSSFIRE with the exact same setting with Catalyst.
The "AMD Crossfire" option switch just does not appear in the "General Settings".
Every driver and Windows 10 is up to date.
I tried every configuration of the small switches next to the Crossfire connector, nothing works.
I also tried not to pull the connector fully in.
I'm beginning to loose some hair due to this problem, some help would be greatly appreciated ;__;
