Hello, I would ask to, how figure out freezing whole PC when turning on 4GPU in Catalyst Control Center. Freez mostly happens when turning on benchamrk or game. Also after restart, immediately after boot up to Windows.
While 3GPU is set, no problem.
System is pretty stable by using only one of them in system. Or like I wrote, turing crossfire only to 2GPU or 3GPU.
Please help me how to fix that issue.
PowerColor does not have technical support
Specs is: 
2x AX7990 Devil13
ASrock x79 Extreme11
Enermax Platimax 1500W
I've tried use Catalyst 12.8, 13.4, 13.9 and 13.11beta.
Thank you!

Finally, after lot of nerves with it, I installed Afterburner and disable ULPS. This did the trick. No more freeze.

The FAQ section of the forum covers this and many more Frequently Asked Questions. When I have a question about anything, and I go to a forum, the first thing I do is read the FAQ...
