No problem!
Hopefully it works for you. I’m sorry, I completely forgot about Avid compatibility or I would have checked on that. I haven’t been using Avid lately so it slipped my mind.
The 341.21 driver is not that old (I believe 347 is the current version) so hopefully it will work but if it doesn’t appear to be, I found some newer modified drivers. The guy’s over at forums.guru3d.com keep up on it pretty well. Here are the forum threads and modified files for the newer versions:
Nvidia Quadro/Grid 344.11:
I’m not entirely sure if this one is Avid compatible as I can’t seem to find any info on this version in particular. That may mean it works just fine :-).
Nvidia Quadro/Grid 344.11 WHQL + inf modded for all geforces
Modified 344.11 INF Download (from the forum thread)
Nvidia Quadro/Grid 347.52:
One guy had trouble with this version it seems but I think he may have worked it out, it’s unclear. Here is the thread. As another guy on that thread mentions, the PC Geforce drivers don’t seem to have full OpenGL hardware support. This is one reason I like to go this route. I think it basically solves that problem. Just my opinion though!
Nvidia Quadro/Grid 347.52 whql + inf modded for geforces
Modified 347.52 INF Download (from the forum thread)
Hope that helps!

I just want to clarify (I also modified my previous post to reflect this), once you have overwritten the .inf, you’ll want to run the setup.exe in the International folder. You’ll not want to run the original setup that you downloaded (usually something like this “341.21-quadro-desktop-win8-win7-64bit-international-whql.exe” or something similar) or otherwise it will overwrite the modified inf while extracting again from scratch.

From what I can tell, you should be able to accomplish what your trying to do but it takes a little bit of doing. I’ve done something similar in the past. It might sound strange but you basically have to trick the Quadro drivers into working on a Geforce card since by default that is disabled by nVidia (that way you are forced to buy an equivalent Quadro instead, etc etc). You basically have to replace the information file (.inf) that comes with the Quadro drivers with one that allows you to install those drivers on Geforce cards as well.
What version of the Quadro drivers are you using? If your using 341.21, I can give you the required file right here: Modified Quadro Driver INF
Basically once you have the above file downloaded, you’ll need to copy the downloaded file, then find the extracted driver files on your computer. Typically when the nVidia drivers are extracted, they go to “C:\NVIDIA\DisplayDriver\341.21\Win8_WinVista_Win7_64\International\Display.Driver” or something similar to that. It may be different for you but the main thing is, you need to make it into the Display.Driver folder. Once you are in that folder, paste the downloaded file. It will ask you to place the original. You’ll want to choose yes (overwrite). If it doesn’t ask you to overwrite, then you’ll need to check and make sure your in the right folder.
After that you should be set. Just reinstall the Quadro drivers for both cards (the K4000 and the 970) by running the setup.exe in the International folder, then reboot. You won’t want to run the original nVidia file you downloaded as that will overwrite the modified .inf. You’ll want to make sure the Geforce drivers are completely uninstalled before installing the modified Quadro drivers also.
I should also mention, that file I gave you will only work with version 341.21. I’m sorry that’s a little bit older and you may have to download it from nVidia’s archives but it’s only only version I found really quickly that should be stable. Unfortunately I wasn’t able to test it yet either as I’m currently on an EliteBook (in the process of moving so don’t have access to the workstations right now) but it should work just fine.
Hope that helps! If not, let me know, we can try something else.

I wanted to add, I mean nothing against anyone who uses Geforce drivers! I’ve used them plenty! I just wanted to mention going the other direction in a professional workstation might be a better option.

Hi Timo,
When we ran multiple cards in our workstations, Davinci typically would only recognize the cards not connected to any monitor’s, therefore being recognized as “processing” GPU’s only. Also I mght mention the lite version will only recognize one, again typically the one not connected to any monitors.
I’ve run the 670 4GB card with Davinci and never had any problems using DNxHD 220x and ProRes footage. Worked beautifully. I did run into problems with PCI-E lanes not being mapped properly on certain boards in the way’s it might appear obvious at first.
I suggest grabbing a copy of GPU-Z, fire it up and select your processing card then stick it some place where you can see it. Then fire up Resolve and try to stress the card a little. See what the PCI-E link shows as they vary dynamically based on load. It will tell how many lanes are assigned (4x, 8x etc) and the revision (1.0, 2.0 etc). That will let you know definitively if that is your bottle neck.
If that doesn’t work, we can try something else. I had trouble several times arranging our 10BGe Chelsio & Decklink cards in just the right place to keep it from throttling down the main GPU. Also had to plenty of configuring.
Some have mentioned about using Geforce drivers on Quadro cards. IMO that’s a BAD idea! Reason I say that is as i recall, there is some forms of acceleration that rely on the Quadro drivers, especially OpenGL performance. Also the Quadro drivers are designed for precision & quality. The Geforce drivers are designed for gaming and will basically sacrifice quality for speed typically. In the past, we would use Quadro drivers on Geforce cards and frankly the resulting image quality was much better.
