I now have gotten 3 invalid GFN19 results - 1 per day.
I think this first happened after unsuccessfully trying to do a major windows update to take the OS from 10.00.18362.00 to 10.00.19041.00 (version 2004). The work done has also dropped by about 10%. As far as I know, on my 3 x 2080Ti cards - all exactly the same card - I have never gotten invalid results for anything before. CPU work seems fine. GPU temp is 68 degrees C which is normal for GFN19.

Any ideas?

I thought I should look at the stderr output of some pending tasks.

1 of them had this:

I managed to do the windows update!
I had tried 3 times previously.
I will test the theory that somehow this was the cause of the problems.
That windows had got into some sort of limbo by not successfully completing the update - and this had messed with the graphics card

I had GPU processing spit its dummy out once during/after an update that froze the machine. In an ideal world, pause &/or drain cache before updates.

Windows may have already done a GPU software update even though other parts of the update failed. Windows drivers are notoriously bad. Suggest go download the NVidia Driver updater uninstall the current driver and have NVidia install the correct driver.

No need to. Once the windows update was successfully installed - it was a BIG update - the card went back to normal. And having got it working properly, it is on a holiday until after the TRP challenge - it works best to run 4 of 4 core tasks on that CPU for TRP - so I don't have any cores for the GPU. I am running TRP already because it is my last LLR to take to jade (Woodall will be there in the next day)
