New 7970 Crossfire Concerns

post #1 of 11
Thread Starter 
Hey guys. I just picked up a crossfire setup for the first time and am having some issues with artifacts. These issues are introduced in 3dMark, Crysis 3, Sleeping Dogs. Farcry 3, ect.

The model of 7970s I got are the XFX R7970 Double Dissipation cards, with standard clocks of 925/1375. I have not attempted to overclock these.

I am running both of these cards on a XFX 850 Watt single rail PSU. Not sure if that is the issue or not.

I had some issues with sensors and monitors my cards via my desktop gadget/MSI afterburner because of something called ULPS. So I found a thread on what the issue is.

I went into regedit, and typed in, "enableulps" and disabled all the registry values that started with 1 and made them 0. The official thread didn't include these directions, and only said to disable a certain keys - http://www.overclock.net/t/667144/crossfire-disabling-ulps

I just disabled all of them found in the registry, not sure if this is the issue or not.

Now I start out with download the 13.2 beta drivers. I never seen a 13.2a,b,c,d ect, so I am not sure which version they were. It was just off the official AMD website. I installed the drivers with a fresh install, rebooted and installed my up to date CAP profiles and rebooted again.

I got a few free games with my cards, so I booted into Farcry 3. After setting everything to max and using HDAO (Or w/e) since it's made for AMD I was instantly greeted by a flashing crazy screen of lights. It happens sometimes, and only a forced reload will fix it.

Sleeping Dogs, I am getting little odd square artifacts that are usually in the same area no matter where I am looking. Via the left side of the screen in the middle, or in the middle of the bottom of the screen.

Crysis 2 I get green artifacts when first stepping outside, or flashing skylights when looking through grates sometimes. It doesn't happen alot, but it does happen.

Just Cause 2 was extremely glitchy, and looked like the problem experienced with the Black Ops 2 support for the beta drivers.

I figured all of this was due to the beta drivers I downloaded, so I wiped them and used driver fusion in safe mode to remove all remnants of files and installed the latest stable version, 13.1.

I had to disable ULPS again, and I used the same method as before, disabling everything in the registry with a key -"Enableulps 0x0000 (1)"

And am now getting more artifacts so far in 3dMark free version, and Crysis 3.

I have yet to do anymore testing, but I am concerned I may have gotten a bad card, or my PSU is not up to par.

Can anyone suggest a surefire method to testing this to see exactly what the problem is?

If you bench how are your temps doing ?? Do the cards get really hot ?? You could monitor your temps with MSI AB

First job has to be to test these cards singularly mate, at stock clocks with stock CPU and Ram speeds too.

If they both pass, then you can look at Crossfire problems, which could possibly have been caused by the caps your installed not being compatible with the primary set installed on the driver set.

Firth things first mate, take card 2 out and test one on its own, note your results taking a close look at core and vrm temps using "GPU-Z" then try the same on the second card.

I've tested both cards and they pass with flying colors. Only when put into crossfire mode do they produce artifacts and problems in game. Even create artifacts on my desktop when not doing anything. I contacted Tiger and they are taking these 2 back for an exchange. Hopefully it's just something to do with the cards.

Without crossfire enabled, both cards work flawlessly. I am using the up to date caps with the most stable driver released and installed on a clean slate. Everything should be fine.

How bizzare... I wonder if its a problem with the crossfire bridge.
Are they changing that too?

I've tried both crossfire bridges, same results. I've also plugged in the monitor to the bottom video card and tested for artifacts at full GPU load, so my PCI lane isn't damage I don't think.

I am sure a 850 watt PSU is up to snuff for 2 of these cards and all my accessories. I really don't know. Each card works fine by itself, but put them together and enable crossfire and I get artifacts everywhere, on my desktop.. youtube videos.. every game. Not really sure. I've ran crossfire 6970s in the past with no issues. I uninstalled the drivers and tried the beta, same results.

Has to be a problem with teh crossfire communication circuitry on one of the cards as even with a 300w PSU it would be fine on the desktop mate.
Verty odd, first time I have read of this problem, I hope it turns out well for you, I bet your really annoyed and frustrated!

Hey mate, I run 2 7970's on my Corsair AX850 - you should have no power issues.

The problem presented itself quickly. Testing isn't that annoying, I just should of never tore down my case and installed them then closed up my pc again. This next time I am testing them straight out the door to make sure they are stable.

I still have a gtx 580 to fall back on, and some games to play so it's not the end of the world. I just hope the new ones that show up work correctly while using and not using crossfire. Dropped 800 dollars on these 2 cards and expected better results. But it happens.
