Thanks! I knew it was somewhere..

Well, in case someone is still interested in this subject: I have found that the PSU didn’t have such a big impact after all. There’s still noticeable differences between these systems. My older Ivy Bridge is still the more responsive system, even if it can’t run as many nodes as the 3930K – system. The lack of responsiveness with the more powerful computer makes it a pain to work with. It’s somewhere between half a second and a second of lag between adjusting and something happening on the screen, and it’s sometimes too much. I’ve also worked with a HP Z820, which is a great and solid system, but it also has more lag than my old i7 2600K Ivy Bridge. I’d really like to find out what’s going on…

Today I installed the Quadro 341.21 driver with the modified inf -file. Both GTX and Quadro cards seem to work great, with both Avid and Resolve. This was a great solution, thanks again!
-
Some people are reporting the 341.21 driver is working fine with Avid, so I’ll give it a try first. Thank you so much for finding this all out!

Ok thanks, that sounds like worth trying out. The quadro driver version is 340.84 at the moment, so it’s even older than the one you suggested. I’ll have to check if Avid works ok with the 341 driver.. it seems to be really picky with the drivers. The Z820 is being used almost 24/7 so it will take some time before I’ll get the chance to test out.
The question that comes up for me is wether or not these older quadro drivers are using the full potential of new 970 gtx card.. but I guess we’ll just have to see about it.

Today I installed the GTX 970 with the Quadro K4000. Installed the Quadro driver, after which the GTX card didn’t work. Installed the GeForce driver from Device Manager (update driver), didn’t use the driver install wizard. Everything worked fine in Resolve and performance was very good.
The problems came when starting Avid, part of the displays were missing, only timeline and bins visible. Looking at the nVidia Control Panel and Device Manager, it also looked like the Quadro driver had been overwritten by the Geforce driver. The only way to get Avid working properly was to uninstall Geforce driver and re-install the Quadro driver, and detach the GTX card.
Any ideas on how to get Avid+Resolve working with this kind of setup? Or is it half an hour of installing procedure every time when swithing between applications?

Ok so it looks like there are lots of things to try out. I’m running with Geforce drivers for both cards now, as several people have said it’s problematic to run two different sets of drivers, but I will try to install separate drivers for each card. And it could be worth trying with the Quadro driver as the only driver.
I’ll also try the Blackmagic card slot configuration and see if that changes things.
Glenn, the monitors are connected to the Quadro card, and the GTX card is not connected to anything else than PCIe lane. And yes it’s a dual Xeon configuration.

I have the PCIE cards configured somewhat differently than the guide suggests, as there’s an ethernet card that seems to work only in a certain card slot. But the GPU:s are installed both into 16x card slots.

I’ll have to check when I get to the office next week if they’re showing in the computern management. I know that they are both showing on the NVidia Control Panel. And the K4000 is working, as it’s the one where the displays are connected. Resolve just doesn’t seem to “see” it. On the other hand, Avid does see it. And it certainly seems like Resolve is not using the K4000 efficiently. When I’m using the internal scopes in Davinci, the performance drops from realtime.
I’m on the same graphic driver version 340.52 for the same reasons (Avid). But now theres a need to update the driver for a new card we just got, since that driver doesn’t support the 900 series cards.
I wish Blackmagic would be more clear with the driver recommendations…
-
No expansion chassis, just the HP Z820 which has enough slots available.
I haven’t found instructions on what kind of driver setup is best for Quadro+GTX cards, but from some forum I run into advice that one driver – GTX – should work with both cards. So I’m running a 340.52 GTX driver. But I’ll have to change it anyway as we’re updating to GTX 970 card and that driver is too old for it.
So what’s the procedure of installing two different driver versions on the same system? Is there something to take into consideration
