Put the 4800 as the GPU and system runs a little faster in DaVinci.

Does the GUI card make any difference at all to performance of DaVinci or totally irrelevant?

Thx

Never mind, got it working. For some reason the /System/Library/StartupItems folder was not owned by the root account so the CUDA.kext driver was not loading at startup. “sudo chown root:wheel /System/Library/StartupItems” fixed it.

I will experiment with cards when I get the chance – I thought the 4000 would be better as it has more CUDA cores, but maybe there are other factors that will make the 4800 work better? I know it has more Vram but I thought the big thing for DaVinci was the number of CUDA cores.

Progress!!!

Thanks Dwaine….installed that driver and no error message or crashes….

However when I look at “About – Resolve” it says 1 GPU. Is this correct (I have one for Displays and the other is meant to be for processing only – how do I know if the 4000 is actually being used?

Thanks

Additional info:

In System Profiler, when I click on the PCI cards; for the NVIDIA Quadro 4000 it has:

NVIDIA Quadro 4000 – Display Controller – Driver Installed – Yes
NVIDIA Quadro 4000 NVDA, Parent – Driver Installed – No

However as far as I can tell I have installed as per instructions…

further to this I told davinci to ignore the Blackmagic card and Cooper control surface and tried to load some media and the crash still happened so that appears to rule out either of those devices being an issue.

Also…..

As soon as I try to import any media to the media pool or an xml Davinci crashes 🙁

Still no luck on the CUDA issue as well.

Hi Dwaine,

Did that and no change…..btw I believe we already had that installed…..but did it again to make sure…..

Anything else we can try?

Thanks for the prompt response BTW!

Yeah… Thing is other speed ups seemed to work fine and for some projects a quicker and less fussy round trip is important….

[Andrew Sableton]

Now another one…..

A short clip (12 frames in FCP timeline) is sped up by 1888% in FCP. This clip shows up black with a red cross through it in Davinci. When I check back in FCP all is fine. When I try to force conform I get the message “The Replacement clip is too short”. However I can replicate the exact speed effect with the source media manually in FCP so I know it is not too short.

Any suggestions other than baking?
