This all started while I was trying to overclock my new CF7970 GHZ setup.
I have been busy benching and hit the wall at 1175/1700@1.263v, so as you do I have backed the overclocks off a bit and have now successfully tested 1125/1600@1.250v in the following programmes:

Heaven (Maxed)
3DMark
Company of heroes 2
Battlefield 3
Metro LL Benchmark (2 loops)
Furmark

However Crysis 3 is where my problems begin.
I tested what I thought was my new stable everyday O/C (as above) and I got a BSOD, unstable overclock I thought, So I back off down to 1100/1600 and 1.263v and I got the same result.
I then returned both GPU's to factory and this would result in the game freezing/BSOD or DXGI ERROR DEVICE REMOVED (which I have only received once).
I have now tried underclocking and trying different drivers still with freezes and crashes.

Can some-one shed some light in whats going off, I find it hard to believe one of my cards are faulty when all other games run ok, the game is patched to v1.3. My only other thought is my PSU TX750W isnt cutting my system and this game (other hardware includes 3770k @4.8) But again why would it work in everything else fine.

Please HELPPPP!!

crossfire/sli is a one big piece of sh!t, go buy gtx titan or wait in month there would new amd series, Dat DXGI is oc error!!! there is something wrong with gpu core, or you can try update latest bios gpu which may fix ur problem with gpu stabillity but its dangerous to play with bios..

btw prettty nice 4.8ghz in which shop did u bought dat i7 ?

C3 is a finicky bich when it comes to overclocking. Not just GPU's, but CPU's as well. Had to back down my CPU OC 200Mhz only for C3.. Strange. But anyways..
MSI Afterburner? if so uninstall it. Never worked for me either. Running Tri7970's at stock and no higher.

Also, uninstall Graphics Driver then reinstall.

Try messing with your CPU. I have the same 3770k, but I have a gtx690. I can OC my cpu to 4.8ghz with everything except C3. I've found that 4.5ghz is the sweet spot for me with crysis 3. at 4.6ghz i crash every other game. Also how your ram? are messing with any cas latency timings?

try backing the cpu down to stock and see what happens.

Well, you and I have a very similar set up.

I had 2x7970 Ghz edition cards OC'd, I have a 4670K OC'd, and I have a TX750. The only reason I said I had 2 of my GPUs, was because I sold the other afraid that my TX750 might not be be able to handle everything. I might do this. Now I had a lot of problems with C3 when OCing/setting up my system and I'd like you to try a few things:

1. Reinstall Crysis 3.
2. Do a CLEAN install of your radeon drivers.
3. Return everything to stock. Join a MP game, look at the usage of your CPU and GPU. Is either one maxing out? If either one is maxing out, and causing the crash, step up the voltage slowly. This will not reduce the usage, but it will help the instability. Once you find a good voltage where you're stable, then you can begin your OCing for games like Crysis 3.

My final resutls were:

CPU: 4.7Ghz vcore: 1.31V uncore: 1.34V
GPU: 1150/1600 vccore: stock (1.3V)
