the pc where the card in is, is a Antec Earthwatts EA 500
where it was in but didn't work zalmann ZM600-HP

I also think it's something to do with my powersupply.
because HD4870 who also needs 2x6pins crashes now( windows update, crash, bluescreen )
and geforce 8600gts hasn't that problem ( and that card doesn't need any 6pin power )

i was first afraid that Pci-Express 1.0 was to old for such a powerfull card
or don't they need power also from the slot itself?

just making an assesment that it might be the psu. just imagine now u are using a 6970 which require a 6 + 8 pin (even thou the xtra 2 pin are jus ground). But basically the 6970 require more power than the 6950. the 6970 require a psu with a 6 pin and a 8 pin.

just pure speculation thou :roll:

I have an HIS 6950 and have installed the ASUS 6970 BIOS linked by the OP. The card works fine, but when I try to start SmartDoctor I get the following message:

"Can not find graphics card information"

SmartDoctor then immediately closes.

I have tried uninstalling all Asus and ATI software / drivers and starting over but ended up with the same problem. GPU-Z shows my card as an "ASUS EAH6950 Series"

I have tried drivers from both ATI and from ASUS.

Any ideas? I would love to try out SmartDoctor to see what kind of overclock I can get.

nice try :cool: but i'm going for this one : Seasonic M12D-850 ( to have a little more headroom :rolleyes: in silence )

what I hated the most on my zallman was that despite the Heatpipe, it was the noisiest thing in my complete pc grrrrrr.... :banghead:
it has a 6pin and 8pin connector bytheway.

hopefull that is the only thing that needs changing, or the cash i gained by modding the 6950tot 6970 is totally wasted on other hardware :laugh:

Awesome PSU, it's the one I use in my PC and have never had an issue with any video card I've thrown at it including a CF setup. It's also pretty darn quiet.

Hi everyone,
I successfully modded my Sapphire 6950 to an 6970 using the Sapphire BIOS.
I use the standard 6970 clocks and all games run fine (as far as I tested), but some benchmarks (eg 3dmark or the lost planet 2 benchmark) hang after a while and I get an errormessage similar to this:

"Workload work failed with error message: DXGI call IDXGISwapChain::present failed:

Hardware device removed.

DXGI_ERROR_DEVICE_REMOVED"

Does anyone have a clue? I am using the current hotfix drivers 12a on my win7.
Thanks!! :)

Alright, I finally know exactly what is causing my clock issue. I imagine some of you have experienced this without knowing it, and I'd also like to know how to resolve the issue. It could be an IE issue, which I'll check after this post.

When ever I view an Adobe Flash video my clocks shift to 500 and 1375 and will not change when I enter 3D. The moment I close the page that had the Adobe flash video I viewed, my clocks resume. Turning off hardware acceleration did not change the result.

Any ideas?

Mozilla Firefox works. Internet Explorer was the culprit when viewing adobe flash.

Exploder strikes again! :eek:

I guess I'm lucky in that I haven't had any of these issues with 6950. Haven't achieved any great overclock, but it works fine with 1536 shaders.

This is a well known bug related to AMD drivers & Flash or other accelerated video on the desktop - just google for "ati stuck 2d clocks". IIRC, I think it's due to be corrected in either this month's or next month's drivers.

Quick question guys, i cannot monitor voltage after flashing 2 gigabyte 6950s, i used Wizzards tool to flash to 6970, does it increase voltage? if so from what to what? thanks.

Use GPU-Z and switch to the sensor tab. The last meter at the bottom shows the voltage it's running at. You can't change it manually, but you can see it at least.

Actually with the bios provided with wizzards tool, gpu-z does not read the voltage.

Just worked perfectly for my Sapphire 6950 using the batch file you linked. This is awesome.

Are you sure? I could read it with mine. What version of GPU-Z did you have?

Im using the latest one, 0.5.0, to my knowledge this is the latest.

Try running benchmarks in windowed mode and monitor your card's temp using GPU-Z. With my card, I found that after the mod, temps above 91C would result in hangups. Havent tried figuring out if it was the core or the mem, went for the simple solution of upping the fan speed.

I don't know if anyone's answered this but I'm just wondering if everyone is running their fan speed on auto or raising it? I believe the highest I've seen it at during gameplay is 35%.

nm, I raised my fan speed to 60% because I was crashing on auto, now it works fine, although a little noisy.
