I'm a big home theater guy and it reminds me of the days when people were using low quality digital coaxial cable for 5.1 surround and getting bad sound. I believe the same applies for display port when trying to push tons of quality information through them in the case of high end pc gaming.These errors don't occur for everyday business/internet use with display port. Simple fix for this is to run a high end cable for your high end monitor coming from your high end video card. I'm going with these only 60.00 at walmart. http://www.monstercable.com/productdisplay.asp?pin=5410 I've never understood why people would run cheap connections between high end equipment. You have a 500 dollar monitor and over a grand in video cards and your going to link them together with a 10 dollar cable.

Na, I run good quality thick $50 blue-jeans 20 foot DP cables and I still get the problem. Usually with Monster you pay two times the price for the name. There is a serious "diminishing returns" phenomenon with cables. I remember reading an article about some audiophiles doing an A-B blind test with a pair of high quality speakers. They used like $1000 audio cables and compared them against regular electrical cord you would find on a lamp. They couldn't tell the difference.

Im not overclocking my Sapphire 7970 at all and Im ruining the lastest RC drivers 8.921.2 and I still get the "Driver stop responding" error when playing all kinds of different games. So Im not sure is it the early un-mature drivers or my video card. One thing I did notice was my temp is hitting 68c when gaming. Not sure thats too hot for this card.

Did you tried custom fan profile, or setting it manually in Overdrive menu?
68C is safe but you sholud check if goes above 75C in some situations...

Try Furmark X-Treme Burnin (with AA disabled) biggrin.gif, monitor sensors in GPU-z

I ran the GPU-Z error test for both my top and bottom card.

The top card said PCI-E 3.0 x16@x8 2.0 (I'm assuming this is normal, the card is 3.0 running on first slot x16, but running at x8 because crossfire and my motherboard is 2.0)
However, when I try the second card, it says, PCI-E 3.0 x16@x8 1.1

Does that mean the second card is running at 1.1 speed?

I have a Gigabyte Z68XP-UD4

You cant run the 2nd card by itself...
You have to run both or just the first one.

When your running both on the GPU-Z render test....and the bottom stays at 1.1 ...then im afraid it is at that speed..

I would look at the motherboards BIOS for solutions... try default settings.

Thanks all, I think I may be giving up.

I tried pretty much everything, uninstall, reinstall, installed windows update, switching cards, resetting cmos, disabling ULPS, fresh windows 7 install, different drivers, etc. I can't get it to work in BF3. It would work when GPU usage on both are 99% because I would be getting 120+ fps, but once it drops down to 70%, I'm looking at 50-60fps, and it happens quite regularly and you sort of know when it'll happen, at the most intense scene or overview of the map. It's feels like the GPUs are saying, "Okay, I'm taking a break, CPU you take over." I don't have any other games since I built this for BF3, but 3dmark11 and Heaven seem to be fine.

Even the folks who did the 7970 crossfire review over at Overclock3d.net said,

"Battlefield 3 wouldn't run at all, The Witcher 2, Resident Evil 5, Dirt 3 and Batman Arkham City all showed better performance with a single card than the Crossfire set up."

That looks to be what I'm getting. Welp, guess I'll stick with the 7970, maybe sell that for Keplar to go SLI.

You should wait. These cards still didn't get official drivers... especially crossfire driver
