Cuda Driver is not loaded – but it is……

[Dwaine Maggart]

You should go to the Nvidia Driver Downloads site, and download and install the Quadro 4000 for Mac Nvidia driver for OSX 10.6.8, which is driver version 256.02.25f01.

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!

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.

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.

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…

If you are getting NO CUDA errors, then Resolve will crash when you select a file on the Browse page.

Just to make sure it’s fully installed, now that you hopefully have the 256.02.25f01 driver installed, from the same Nvidia Driver Download site, in the Nvidia CUDA Driver for Mac section lower on the page, download and install the 4.0.50 CUDA driver, and see what that does.

If you still have issues after that, please run the Resolve CaptureLogs app, in the /Library/Application Support/Blackmagic Design/DaVinci Resolve folder. When you run this, it will create a .tgz file on your desktop. Send that, along with a .spx export of your Mac System Profile, to our davincihelp@blackmagic-design.com email address.

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

If you are not getting an error about the GPU being used to drive the GUI display, and you have no displays connected to the 4000 card, then the 4000 card is being used to do the GPU processing.

Yes, 1 GPU is correct for your system. The card connected to the GUI display (4800 in your case) is not used for GPU processing.

If you move your displays from the 4800 card to the 4000 card, then the 4800 card will be doing the GPU processing.

It might be curious to do that test, and see which card you think has the better performance in your system.

I would suggest that you use the Quadro4000 for GUI and the Quadro FX4800 for GPU processing as it has better performance than the Quadro4000.

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.
