Ill repost this since ppl dont read all the post (that i understand
The Crossfire connection works (enabled in ccc, shows up on gpu-z and msi afterburner) But it does only work in benchmark, like 3dmark, CSS ingame benchmark, and some game menues, when i start to play the actual game the load drops from 90%+ to 25-30% But crossfire logo is showing so crossfire is enable, aswell the load is 25-30% on both cards. This equals that i have less peformance in games with crossfire since the card only loads 25-30% then a single card that loads 90% +
So i dont understand what the problem is since the card works flawlessly in test but not in games =/
I have tryed this:
-The following drivers have been tested: 10.11 | 10.11a | 10.10 | 11.1 | 11.2 Also the app profiles was installed correctly.
-Clocking down cpu to stock, and up to 4ghz, no change.
-The bios has been flashed, also the card is in the correct slots with bridge connected.
-Tryed another more high power psu, same problem, did 2 psu's together, same problem.
-Tested them on a newer system with i7 cpu, same problem
-Enable ulps and catalyst AI has been set to every option avaible same issue.
-Clocked up, and declocked the cards, nothing changed.
-Changed the order of the card, and turned around the bridge, same problem
-Checked everything in bios, nothing wrong there, pci-e freq is 100 when oc'd cpu, [auto] when running standar bios settings.
