Thanks man, this fixed my problem of non sieve tasks immediately giving computation errors. Clean reinstall of current graphics drivers and it is working (on GFN 22 at least).

Penguin's post below about Win 10 update messing with drivers was the issue. I did a clean reinstall of 397.64 and tried the GFN 22 units again, and they have been going for two minutes without error.

How GC pools its users also messes up the user leaderboards of projects, and it would have been nice if they hadn't co-opted the organic team system to operate also.

But, it is an exceedingly minor thing to disrupt the gamification/community elements of BOINC compared to messing with the integrity of the project data itself.

If the data cannot be trusted then we might as well all pack up and go home.

For the following host:

I used this 1700X with Titan V's for PPSsieve work units during the Pentathlon. It seemed go OK without performance or error issues for those WUs.

Now the contest has passed I tried throwing the following work units at it: GFN 19/20/21/22 and AP27, but it spits out immediate compute errors for all of them. Example:

Stderr output
(unknown error) - exit code -1073741515 (0xc0000135)</message>

The nVidia drivers are the latest 397.64 and I have tried small and large GPU core and memory underclocks to no avail. No OC in this box at all but I do run MSI Afterburner for a more aggressive fan curve. BOINC folder is excluded from Windows Defender also.

The immediate fail symptom was the similar to what I experienced when trying Asteroids but that issue was because the Asteroids application didn't register a CC7.0 GPU as being above the CC2.0 minimum and immediately exited. Unfortunately the errors I got here are generic so I don't know where to start.

Are there other Titan V's out there successfully doing the GFN or AP27 WUs before I generate more errors fault finding this?

Any suggestions appreciated,
