What do you think of this crash?

[Juanlo]

Hi all, I hope you can give me some ideas. I'm using a Rampage IV Formula with an Intel i7 3930k (C2 stepping) and 16 GB of GSkill RAM in quad channel. I have two Radeon 7970s and 3 monitors in Eyefinity. Power supply is a Cooler Master Silent Pro Gold 1000W.

My system freezes completely with some games. Battlefield 3 may crash after 20 minutes or after 6 hours (or not crash at all), but in Serious Sam 3, the crash always happens in less than 10 minutes when starting a new game at Cairo level. I have no idea whether it's an AMD Catalyst problem (I have tried several drivers up to 12.6 beta) or a motherboard/CPU problem. No error message, no BSOD. The computer just freezes, image is frozen, keyboard and mouse stop responding and I must reset the computer.

Everything is at default speed, nothing is overclocked. The crash does NOT happen if I disable Eyefinity. And it does NOT happen if I disable Crossfire. But when using both Eyefinity and Crossfire, bam, system freeze. I have done a new, virgin Windows 7 installation with only motherboards drivers, Catalyst, Steam and the game. Yesterday I also tried the new Windows 8 RC with the new AMD Catalyst drivers, but I get exactly the same freeze.

And here's what puzzles me: normally, when I press the reset button, the system reboots instantly. But when this freeze happens, I press the reset button and nothing happens, the computer keeps frozen. Then, after 8-10 seconds, it completely shuts down and then it powers on again automatically after a couple of seconds.

What do you think?

Here's our current thread about this issue.

Yes I have this problem. My config:
RIVE 2105b
3930k
2 x Sapphire HD7970 (Reference)
G.Skill RipjawsZ F3-17000CL9Q-16GBZH (4x4)
OCZ ZX Series 1250W PSU
Xonar DX Sound Card
3 x Asus VW225N monitors (crappy as hell:() 2 of those connected via active miniDP -> DVI adapter from 7970 box and 3th to DVI via OC Key.
5040*1050 desktop resolution
Some RAID0 disk configuration.

The problem is 100% like on your video posted above. But I use for testing Batman Arkham City instead of Serious Sam or BF3.
Everything else is the same: after 1-10 mins of playing PC freezes completely, if I pres reboot button - PC holds for 8 seconds then turns off then back on. The problem appears ONLY while BOTH eyefinity and CF enabled.

BTW As you can read in the thread I linked above, we've tried everything. Every suggestion of Raja or somebody else was tested by me too with no helpful result. (Gen2 pcie, bios stock settings, forced XMP settings for mem etc etc)

It's very good to know that there's a man here who is in touch with AMD guys. Thank you once again!
