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.

Uggh I hope not - that mb is unavailable now except at an absurdly high cost on Ebay. It's pretty much the only mb for the 2600k that gives me the slot spacing needed to also run a sound card with the 2 6970s and a big CPU cooler. IIRC there was a Gigabyte board too that was OK but it won't be...

Sorry my post wasn't complete as your response reminded me - did run DDU after a 15.7.1 install. I also tried the Crimson version, no help. (AMD is not officially supporting the 6970 on any drivers past 15.7.1 so I was reluctant to try it but figured I had nothing to lose).

I've been running an AMD 6970 driving a Dell 30" monitor and up until recently it's been able to run older games and racing sims at 60fps without any trouble. Suddenly one day a few weeks ago I found that the framerates in some games had taken a sudden hit, to 30-40 fps. Afterburner indicated...

I've got to replace my 2 X 6970 cards with a single current-gen card due to a PCI-E slot failure on my mobo. Can anyone tell me what is going to give equivalent performance from the current AMD and GeForce lines? I don't want to go backwards, in fact I'd prefer something giving better...

^Thanks Rav3n! I never would have expected that kind of compatibility without a big loss in performance. Looks like my best bet. Though it's hard to figure out how any new card performance compares to my 2X 6970 setup, even Tom's charts keep changing their benchmarks year to year. Anyone know if...

I'd been happily using an Asus P8P67 WS Revolution as my Crossfire platform for the last 3.5 years, but the slot for the second 6970 has died and I cannot use any other slot on the board for the second card. (Death of slot confirmed by: card swapping, diagnostic LED on mobo). Unfortunately...

Can anyone offer advice on a 12.2 bug? After installing this (an upgrade from 12.1) I now get an error message on bootup telling me that kdbsync.exe cannot be started up because OpenCL.dll is missing from the computer. Also after going to sleep the screen woke up in 640X480 and could not be...

I just did a build with a n new P8P67 WS Revolution motherboard and immediately upgraded the BIOS to 1402 using EZ Flash 2 with no problems. However I noticed an immediate drop in the reported CPU temp in the bios from about 39 on bootup to a ridiculously low 23 with the new bios - same as room...

Check AMD's web site - IIRC they have some custom cleaner/uninstaller available - check their forum area.

Re that first screenshot of the half-constructed building: maybe it's time for your reviewer to get those reading glasses he's been avoiding... The MLAA does a good job of getting rid of the aliasing, but at a considerable (and to my eye unacceptable) cost to the texture sharpness. The textures...

With a little more research I've found that the Logitech G500 and G9 do mouse action capture in their macror ecording (at least according to a few reviews.)

Thanks for clarifying the obvious. IR radiation is far more efficient in converting its energy to heat than other wavelengths, thus its use for heating. While the IR output of a mouse sensor may be very low it could over time heat up surrounding materials enough to be noticeable, especially when...

In all the reviews I have read of the 1st and 2nd generation Adders nobody has mentioned a problem I discovered five minutes after plugging one into my computer today - the thing gets as warm as a toaster. I noticed that my mouse paw was getting unpleasantly warm after a few minutes of constant...

I was hoping a Razer would allow me to capture/bind things like ctrl-click and alt-click with its macro software but it does not. Anyone know of a mouse that does provide such functionality in its macro software?

I know nothing of the innards of keyboards, but I was never crazy about the 4000 series MS keyboard I was using; on a whim I decided to try an Adesso ergonomic (I love the split layout for ease of typing and lower mis-keying). It was and still may be available through Dell Canada; very...

You might have a card or headphone problem - that card (which I just bought but can't use till I build my next system with PCIe) should handle the 40 Ohm impedance of the phones you are using easily -it is rated for30-330 Ohms.

Great, thanks - picking up an AX850 today or tomorrow before a rebate runs out and plan to put it in an FT02 case for upcoming build (waiting a few weeks for Sandy Bridge and AMD 6800s).... .

So that is what - about 15-20% of the PSU fan being covered over? That might introduce a lot of air turbulence which could increase noise. Do you hear the psu at all above the video card when idling?

Teiresias - when you say it still doesn't line up with the vent - what percentage blockage of the fan intake do you get? And did you ever try the reversed layout you mention?

It's at Cnet Australia: http://www.cnet.com.au/dell-ultrasharp-u3011-339305812.htm Good color gamut and calibration accurate after adjustment, moderate input lag (27 millisec or 1.62 frames on average). Rated 9 out of 10. It's available for order in the US, but not available yet through...

The earlier solutions I offered did not work under all circumstances, so I went with a "hard" fix - I ran the the Refreshforce permanent solution and it worked fine. Run it once and you are done. Google it to find the app.

It's a driver not a hardware problem, since without the driver 120hz works fine in games.

1. press button on monitor that brings up list of options 2. press button labelled "menu" 3. onscreen display menu appears showing brightness and contrast levels - look at extreme bottom, left hand side of the onscreen menu - resolution and refresh rate will be listed eg...

Press the menu button - the running resolution appears at the bottom left of the popup menu.

If you use an ATI video card and find that you cannot get the refresh lock in the CCC to set the display at 120hz for some games (it did not work for me with GTR2), you can download ATI Tray Tools and use it to lock the refresh rate. However with TT enabled the CCC's and the in-game AA and AF...
