not sure if the Sabertooth BIOS has the same BIOS features as the ROG boards, but if you do go into the BIOS PCI-E setup and it will list which slots you should be using, specially if you want to setup crossfire, also it'll list which ones are 16x vs 8x

Weird, Both PCI-E are running at 8x, shouldnt it be 16x and 8x?

try other games like BF3. Heaven 3.0 also is a good test. If it scales well in these 2 apps you shouldn't have anything to worry.

Are your fans on auto. maybe manually setting fanspeed is a better option. My ref HD 6950 with 50% fan speed is not loud. Aft 60% the fans noise is clearly audible but not disturbing. So ramp the fan speed till the noise does not become too loud for your convenience . thumb.gif

Hey everyone, I got my VisionTek Reference 7970 in a few days ago.
It runs just fine when I'm not loading up a game, haven't seen any problems there.
But whenever I go to load a game, I keep getting black screens and the hardware disconnected/connected notification, then the screens will come back on for a second or two, before a rinse/repeat situation comes into play where I have to kill off the game I loaded, then it goes back to seemingly running just fine. This sounds like the "Display Driver stopped responding and has been reactivated" error, which I've seen a time or two pop up during the course of this.
I tried the 12.8 drivers from the catalyst suite install (full suite used), the 12.4 from the VisionTek disc, 12.6 from AMD website. I reformated, then loaded just the windows updates that showed up, tried the 12.8 drivers again, same problem (in Darksiders II), uninstalled, loaded 12.6 again, tried the MSI AB -xcl method, rebooted, set my two profiles. Same problem.
I have two dvi monitors hooked into the displayports through active adapters, and have a third waiting for me to run three monitor eyefinity (with hopefully a 4th line going to our tv for watching movies).
But I just can't seem to get the card to run my games at all without the display drivers crashing. I'm at my wits end on what could be the problem, read through as much of this thread as I could, searching to see if I find some answers. But nothing I've tried has worked thus far.
Just in case, here are my specs:
2x Asus VH236H monitors (ran displayport active adapter to dvi)
ASUS P7P55D PRO LGA 1156 Intel P55 ATX Intel Motherboard
OCZ Fatal1ty OCZ700FTY 700W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply
Intel Core i5-750 Lynnfield 2.66GHz LGA 1156 95W Quad-Core Processor BX80605I5750
COOLER MASTER HAF 932 Advanced RC-932-KKN5-GP
CORSAIR Vengeance 8GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9
The machine was built a year or two ago, I had an ASUS EAH 4870 1GB in the system, I took advantage of TigerDirect's recent sale to upgrade to the 7970, which is giving me so many problems trying to run games.
A third of the same monitor (VH236H) for eyefinity working and a samsung tv for the 4th line out eventually once gaming is stable is planned and ready.
The GPU temp sits around ~60C, fan speed at 29%/1375 rpm
I haven't changed the voltages or fan speeds, just most recently have done the 2D/3D profiles through MSI AB as pioneer suggested, 2D at stock, 3D at 1000MHz/1500MHz.
When the display driver crashes when games load, the speed drops down to 300MHz/150MHz at times.
Just so frustrating and I'm at my wits end trying to figure this out.

Anyone have any ideas with this?

I experienced artefacts, in my scenario it happens when you overvolt the card, it doesnt happen at stock volts, second thing is that not all Tahiti chips are affected, third i think majin reported same think with his HD 7970s.
The artefacts are really minor, most people wont notice them, but i have eye for these things.biggrin.gif

Someone here mentioned that his card would run up to 80C without problem on stock clocks/volts, but when he overclocks/overvolts, he would starts to see artefacts somewhere in mid 70s.

You would probably crash, again only if overclclock/overvolt, if you hit 90C.

On stock VID, HD 7900 ASIC can sustain up to 95C.

But what i also found that if you can keep you temps low, you will need far less voltage for you OC.

My Asus HD 7950 DCII that i sold to my friend for example, in his PC it need way less voltage than in mine for xx clocks.
Reason is that he uses custom fan profile that keeps card under 60C all times, and i have used auto fan profile.

So after all artefacts that i have seen were maybe because not enough voltage/overclock was not stable.

If you are stable, with no strange things on screen, you are good to go, enjoy the card.thumb.gif
Hope this info helps mate.

Yeah scales well in those 2. Temps even lower in bf3, didn't break 51c core and 41c vrm heh and that's at 1.3v/1225 core not stock. Too bad I thought crysis was the one AMD was supposed to do best in redface.gif

I'm quite impressed with these temps after being SLI 470s for the past year plus. If I didnt know any better I'd think I was under water.

Hi, I'm having issues with my Radeon 7950

I bought a Gigabyte Radeon 7950 with the windforce 3 cooler two weeks ago to replace my GTX 470. While playing Shogun 2 I have system lockup problems where during battles my system would freeze and sound would enter infinite loop.

The sound and lockup is similar to this video: http://www.youtube.com/watch?v=04yss2SWlWg

I googled it and saw that it was a common problem for Shogun 2 and Radeon 7900, so I started playing other things. Now I'm getting the same lockup problem with Civ V, other total war games, and the shooters that I play.

After some googling some people suggested it might be PSU problems. I'm not overclocking the 7950, and I'm using the same system as with my GTX 470 which I did heavily overclock. I also disconnected some extra HDD's to try to rule out PSU problems. I have also fresh installed windows 7 to clean out any lingering drivers and such. I'm on Catalyst 12.8 Beta (though I have the same issues on the official AMD releases).

Does anyone have any suggestions for this? Do I just have a faulty card?

test with a single monitor and connect to the DVI port on the graphics card using a DVI cable. If your problems persist with just a single monitor just RMA the card.

I thought that cards are ok till 85c and even higher. I will do a custom fan profile but right now the card runs champ. I dont feel that i need to oc honestly. The 7970 is kicking ass at 1080.
