This morning I have had a string WU's error out. The screen goes blank and the GPU fans run at max RPM. Here is an output:

Any suggestions?

Card has gone wonky in the system. Reboot the system.

Reboot did not solve the issue. It is crashing on Milkway@Home also. I guess the GPU (RTX 20880Ti) has issues. The driver version is 27.21.14.5206 and it ran fine on that for several weeks.

This GPU is fairly new, it is disappointing if it is failing already.

CI, did your windows 10 recently update? (mine did)
That seems like it could be a driver/OS glitch. Maybe the next driver update will fix it if others are getting it while gaming.
Meanwhile, try testing the card with GPUPI or another math processing tester.
I would also experiment with re-installing BOINC, just in case the ACEMD file became corrupted.

I believe there was an OS update a couple of days before the GPU checked out. I did a restore to roll Win10 back to see if it would solve the issue - it did not.

I tested it with both PrimeGrid, Milkyway and then stressed it with OCCT - the GPU failed all three. I replaced the GPU with a Radeon and another Nvidia and they worked fine in the failed GPU's slot.

Unfortunately, I think I have a RTX 2080 Ti paperweight now.

I think M$ updated your driver to their version which does not have OpenCL support and possibly normal CUDA support. Your reported driver version is NOT a normal Nvidia driver version.

Remove the M$ driver and download the correct latest driver directly from Nvidia.

I had a similar problem once and it turned out the PSU had a couple burnt pins. You can check that along with the power cable(s), but if you used the same connection in the other cards you tested it can probably be ruled out.
