CPU - AMD Phenom II X6 1090T
MB - GA-890FXA-UD5
RAM - 16GB
Vid Cards - Radeon 6850 x2
When I turn the computer on with both installed crossfire bridge installed my monitor does not detect and video output. I can remove the bridge and run each card separately in each MB slot with no issues. It only happens when I have the bridge setup with power applied to both cards
Which card do you have the monitor plugged into, top one right?
-Make sure you have GPU 1 in Slot_1 and GPU 2 in Slot_2. Slot 3 heads to the south bridge instead of the processor, there are often issues with that.
-Make sure each card works by testing each one separately in a single GPU config.
Sounds like the MB is having trouble recognizing crossfire. Which leads me to believe your bridge is broken. IF you have another try using it. I just messaged my friend who has this board and he says crossfire works fine with his 6870's. I know AMD cards come with crossfire bridges, so just try a different one. Make sure the bridge is plugged in the right way too (top of bridge facing back of case.)
So I wiped my drivers and reinstalled the drivers. I can get it to where I can see windows loading and everything past windows loading works fine, but now I am unable to see the rest of the system start up and the monitor flashes as if it were trying to detect. But I guess I can live with that lol
