Ever later than driver version 376.33 (last good driver), cuda units error out. the latest message is:

SETI@home | task postponed 180.000000 sec: Cuda runtime, memory related failure, threadsafe temporary Exit

Going back to 376.33 works fine.

I thought there was a solution to this but couldn't find one easily.

What am I missing?

Why not update to Lunatics 0.45 Beta 6 and select the the SoG GPU app instead of using any of those old CUDA apps?

You're using the oldest Cuda32 ATM which is likely causing your problem when Cuda50 would've been better, but the SoG app will be even more productive than any of those even if you have to reserve a CPU core for each task that you run on that GTX 970 (you should be able to run 2 tasks at a time on that GPU meaning that you have to reserve 2 CPU cores to do that).

Cheers.

Looking thru your task results (And I am not an NVidia person), the error looks alot like the kind I get on my AMD when I use too high an -sbs setting in the command line. You might want to get with Wiggo and check your settings.

Fwiw, I've been fighting this issue for quite some time, on 5 different machines, and pretty well came to the same conclusion that much past 376 there's an incompatibility. Initially, I thought it was a hardware problem with PCI-E extenders I was using to add external GPUs, so I wasted a ton of time chasing that. Coupling that with Win10's insistence on updating drivers without permission and it becomes a real issue.
As with some other suggestions in this thread, I'm retiring Cuda50 in favor of SoG apps included in the Lunatics Beta 6. Perhaps now I can put those extra 980s back to work.
[feeling extraordinarily stupid about not checking this message base about this earlier.]
