CUDA Compute Capability

With the latest version of Resolve requiring nVidia GPUs to have a minimum Compute Capability of 5 (instead of 3) for CUDA 11, you can check your GPU here.

UPDATE. My Error It should say 3.5 NOT 5.

I am using the latest and greatest from Nvidia (see signature) which worked perfectly until today - I updated to 16.2.7 and got a CUDA error message. Not funny

And no, there is no new driver available.

Edit:

There is no new official driver available for Ubuntu/Linux Mint etc. but there is a new driver 450.x in the pipeline, hopefully with CUDA 11 support.

Dieter, 450.66 has been available for Linux since August, and supports CUDA 11.0.

I am running that driver and I am getting the same error.

Are you on CentOS 7?

I am running Fedora 32

I will test on CentOS 7.8 this week.

Seth, it doesn't show up in my driver list. I guess I'll have to add the driver PPA to get the latest

Yes Dieter, you'll have to add the graphic driver ppa to have the option to install 450.66
You can check the CUDA version by running nvidia-smi in the terminal.
Quickly tested 16.2.7 on my ubuntu 20.04 system with 450.66 and all seems fine.

That's strange I ran it on my system and it does have CUDA 11 but Resolve doesn't detect the card as compatible which is a GTX 1080 Ti.

Code: Select all

That's strange,
other programs that need CUDA are working for you? e.g Blender?
maybe some package/lib is missing?
Unforntunately I'm only familiar with debian based distro and cannot be of any real help.

That's a good idea. I didn't see the card when I looked for it with Blender either. I decided to try reinstalling the NVidia driver and that seems to have fixed the issue. Kind of strange that it worked but maybe when I did a kernel update not everything was installed properly with dkms.

Okidoki, I updated to 450.66, all works fine. I really dislike to update my GPU driver more often than I have to since it's a core component (not only for Resolve) of my stable-as-a-rock system

Anyway, thanks for the neccessary kick in the butt.

16.2.7 Studio running fine on CentOS 7.8 with ELRepo's 450.66. UI feels a little bit snappier, too!

16.2.7 Studio also running great on CentOS 8.2 with ELRepo's 450.66. Be advised though that you'll need the selinux-policy-3.14.3-41.el8_2.6 package, which has been out for a couple weeks on RHEL 8.2 but I literally only got in the last hour or so on CentOS 8.2.

I suggest that you clear your dnf cache with:

Code: Select all

$ sudo dnf clean all

Then update to get selinux-policy-3.14.3-41.el8_2.6:

Code: Select all

$ sudo dnf update

If for some reason you're delayed on getting that package and are stuck with selinux-policy-3.14.3-41.el8_2.5, you'll need to roll your own SELinux module or GDM will crash when you try to boot: https://elrepo.org/bugs/view.php?id=1022

I am running Win 10, and am getting that same CUDA message trying to launch since the update. I have the RTX 2060. What do I need to do now?

Update your NVIDIA driver to the latest "studio" version. See my sig.

This is crappy - I feel like I'm being punished for having an older card at a time when the cost of an upgrade is difficult. There's a pandemic and work has dried up!!

Now, changing from CUDA to Open CL, it takes 2.5x longer to render my videos.

Not happy!

You do have the option of stepping back to 16.2.6

Got it... Thanks.... Holy cow... Software update and firmware update in the same day. Sheesh. And yes CUDA is back.

@Charles: The NVIDIA docs indicate that CUDA 11 has minimum CUDA Compute Capability 3.5 support, not 5 as you've stated. Wondering where you got that info from?

Dwaine, you are right, of course. Probably a mis-read on my part.

If there's a GPU for display only, does it need min 3.5 compatibility as well?
