Hi all - thanks in advance for your assistance!

I'm experiencing some challenges that I'm unable to resolve by reading the threads. Hoping for some help!

I'm using Debian 9 - with the latest Debian NVIDIA non-free driver package. I've also installed the CUDA dependencies.

Using web settings (not local) and my Windows computer gets work consistently.

On BOINC startup, GPU with CUDA is recognized (my log):

Fri 11 Aug 2017 08:03:57 PM EDT | | CUDA: NVIDIA GPU 0: GeForce GTX 650 Ti (driver version 375.66, CUDA version 8.0, compute capability 3.0, 980MB, 924MB available, 1425 GFLOPS peak)

Log also shows this from GPUGRID:

There are no GPUGRID Apps for CC3 cards using Linux, sorry. CC3 ards can only operate with Windows at this time.

Ah! Makes sense, thanks.

Just curious - what is the minimum card required on Linux?

Just curious - what is the minimum card required on Linux?

Insofar as I can see, it is Maxwell (GTX 9xx) or later. There is no official list; just a lot of reports on earlier cards that don't work.
