I'll try the memory downclock, although the fact that 2 cards have the identical problem doesn't give me much hope for that solution. I'll see if I can partition enough space out of my drive to allow a clean test install, good idea there. Will apps still run after booting from that install?

I've only spent 3-4 hours working on this. Replacing all my apps and settings will take 2 days. 100s of gigs of apps.

Idle loads on both CPU and GPU are very low - Overdrive basically shows the GPU at 0%, and downclocked to 250/150. Voltages are within spec. Will try running the unigine benchmark again with GPU downclocked, but can't lower mem speed in CCC. UPDATE - saw a small dropoff in FPS - down to 24 FPS...

GPUZ has a test you can run to check if the lanes are working properly, and mine are. However your suggestion re cleaning is something worth doing on the other non-functional PCIE slot to see if that might restore it. I'll have to check that heatsink, thanks for the suggestion. One thing...

Thanks for the suggestion, but very doubtful - I have a Corsair AX 850, which produces a clean 850 watts according to reviews - and now with only one card in the system the total draw is 100s of watts lower than that even with the GPU running at 100% load. Also GPUZ shows stable voltages.

My Win 7 is actually a site license version that IIRC has no limits on install #s. My concern is more about the fact that a different mb will require different drivers - is another brand of mb even going to boot into Windows if my Windows has Asus drivers for a different chipset (P67 vs. Z77)...

No forcing in CCC, everything set to "use application settings". Tried toggling morphological filtering, tessellation, vertical refresh, triple buffering, no fps difference.

My card should score about a 32 FPS on that bench actually, as its an MSI Lightning, factory overclocked (940 MHZ vs. the 880 standard for a 6970). Doesn't get close though - I got 24.8 FPS, score of 1038. That is about 23% lower than it should be. I wonder if it would be worth trying to run a...

With a game running the interrupts are never reaching 1% CPU load. The game itself is only imposing a 20-35% CPU load. The biggest user of CPU time after the game is the "interrupts" at about .8%, with the Avira ServiceHost as well as Services jumping up to that level occasionally. The Process...

Thanks - will look for interrupts. Afterburner shows clock and memory frequencies maxed all the time in-game, full GPU utilization.... I have turned off both hyperthreading and core parking, neither help. Game CPU loads are typically quite low.

Swapped out the 6970 for the other one that I had taken out when the other PCIE X16 slot died - it also runs but has the exact same framerate issues so the card is not the problem, it's got to be something in the system. I doubt it's a MB issue as the slot would either work or not work, it's not...

Thanks - I thought of that too earlier today - was the PCI-E bus running properly? When I checked with GPUZ it was good - 2.0 X16 reported running at 2.0 X16 by GPUZ. I used the same preset for Heaven as that review I mentioned so scores would be comparable - DX11, 3D stereo off, shaders...

Ran the Uniengine Heaven v.2 benchmark - according to a review at Kitguru should be getting 56 FPS average with this card, I am getting 36. So something is definitely wrong.

Will test thanks. UPDATE - made no difference.

Anyone know if I could install an ASRock Z77 EXTREME4 into my system without having to reinstall Windows 7 and my apps etc.? Just found this board for a reasonable price and looks like it works with my CPU, should be able to handle the 2 6970s plus the sound card. TIA.
