I've literally been searching for 24+ hours for a solution to something that should have been automatic according to the amd website and my motherboard instructions. I started off by having my monitor and hdmi cable plugged into my onboard graphics. I then installed the onboard vga drivers from my motherboards support cd. i then turned off my computer and installed my amd radeon hd 6670, did the same thing and made sure I had the latest drivers and ati catalyst profile from the amd website. By following these steps I was then suppose to be able to have access to the amd crossfire option in the amd vision engine control center, but to no avail. I've tried dozens of different metods posted by people online and have made sure my motherboard, apu, and discrete gpu card are all compatible and dual graphics ready. What the hell am I missing here? Thanks guys, i'm looking forward to a resolution to this before I go insane.
