Hi, I'm looking for help with the following issue: when enabling crossfire, my computer will freeze on any game I'm currently running, the screen freezes (sometimes with a buzzing sound), and no error message is shown after restarting, these are my specs:

Intel i7 3770k
Visiontek AMD 7970 3GB (x2)
Asus Maximus V Extreme
32Gb Corsair Vengeance RAM
Corsair AX1200w PSU
Windows 8.1 x64

Crossfire was running without issue on a variety of games until recently (built this computer in late 2012), I have tested each card individually and I haven't experienced any problem or crash it is only with crossfire enabled that my computer will freeze after a couple mins while running a game.

I have also tried the following:

-Used a new crossfire cable (I tested a similar new crossfire cable from another Asus Maximus V extreme)
-Connected the crossfire cable on the 2nd connector on the card.
-Connecting the cards to another set of PCI-e connectors.
-Disabled AMD HD Audio.
-Tried different drivers from 2012, 2013, 2014.
-Removed all drivers with DDU and installed 14.9 fresh.
-Reinstalled Windows, tried with a fresh install of Windows 8 (and 8.1) too.
-Different power cables.
-Increased fan speeds on both cards (I considered overheating at some point).
-Updated BIOS.

What else can I try to solve this problem? I'd very like to be able to use Crossfire again :p .

Thanks in advance.

I am assuming your board is socket 1155. Have you tried using slots 1 and 3? If it works the performance will be the same.
Slot 2 may be bad.

Hi, I tried crossfire with slots 1 and 3 and the problem persisted, I also ran the 2nd card alone on the 2nd slot once and it ran without problems, it only crashes when crossfire is enabled.
