While trying to make my new GPU working for boinc on my Mac, I installed CUDA 3.0. Now I found the problem was not CUDA driver but Boinc version and running the 32 bits kernel. Should I downgrade CUDA to 2.3.1a ?

Iam on my 2nd GPU. I have never had to load the CUDA software. Projects will read your hardware profile and load any needed tools.
HAPPY CRUNCHING!!!!

What version of Boinc are you running ?


With 6.10.21, I have "No usable GPUs found" message on two computer
With 6.10.36 or 6.10.43, GPU are found but no credit show on Bam even after many days.

If this is you Jeff LaPointe
I see you are on Windows. I have one computer on XP and it worked right away...

The Boinc client for Mac must have problem with GPU.
Powerful GPU on Mac is a new thing that came with switching to Intel/AMD CPU.

Over on Collatz, they have this on the front page:

For MAC OS X CUDA processing, BOINC 6.10.29 is recommended with CUDA toolkit and drivers 2.2 or later.
