So probably the GPU was working ok. It would be good if we had the startup messages from boinc for that session.

pp:
Hmm, didn't save it. Just saw the regular message about no CUDA enabled devices found and despite the fact that I had suspended the project before I started boinc it still aborted my whole cache.... don't really feel upto trying it again right now. Still filling up the cache anew  :)

pp:
Ah, it was still in the old log.

sunu:
Well boinc couldn't see your GPU but still could be either boinc's or nvidia's fault. You could try:
a) I see you run boinc in daemon mode. I always run it through run_client. Try it to see if it makes a difference.
b) With sli enabled try to run seti standalone with --device 0 and --device 1 to see if it works.

pp:
This post and the fix listed under CUDA makes me wonder if there perhaps was a regression in 190.x...
