Over the weekend I started experiencing Enigma GPU calculation errors on my Linux machine which uses GTX 1050Ti cards. Is this happening to anyone else? The config of the machine has not changed. Last week it ran these units fine, then suddenly they all started failing a couple days ago, despite Boinc & machine restarts.

Seems to be affecting everyone running Enigma GPU v1.12 (cuda_fermi) on Nvidia + Linux. Old WUs on 1.10 are fine. 1.12's probably bugged.

It's not just Linux & 1.12 units though. I have a Win10 machine that is now failing as well with all 1.10 units.

My Win7 machine is running 1.10 units just fine. Can someone from the project comment? I could put a lot more compute resources on this project, except most of it is failing when I try.

Just got some new 1.13 WUs, so far so good! Thanks for the quick update.

I am still getting errors with 1.10 WUs. As my computer previously crunched the WUs just fine and I have experience intermittent WU problems in the past I thought it was just buggy files. However, my inability to crunch has been going on for a couple months now with no good WUs seen. I have tried the various fixes described a while ago and they don't seem to help.

Any help on finding a solution would be greatly appreciated so I can get back to crunching for this project.

I think it's a driver problem:

I am running the most recent driver (397.31) and I am still getting errors.
