I have 2 GPUs, a 1080 and a 980 and when I set "day of work to 0.5, 1 or 2 days BOINC will only run just the 1080 only and will never run any work on the 980. And I still have at least 50 GPUs WUs waiting when it was set to 10 days but setting BOINC to 0.5, 1 or 2 days it will stop using the 980.

Assine GPU work.

Have you set

<use_all_gpus>1</use_all_gpus>
in cc_config.xml?

Does BOINC list both GPUs in the event log at startup, without saying that the second is unused?

It is on. I told you it was running all GPUs and only stopped if I go to anything less than 10 days of work. Setting it back to 10 days starts running all GPUs. That is very odd indeed.

I see nothing that's related to GPU work and why it stopped using the second GPU.

I did the test again. Right now, both GPUs are running and is set for 10 days.

I did a 1-day test and not right away, but it did stop on the second GPU.
I did a 5-day test, and it ran both GPUs for a while and then stopped on the second GPU again.
I went to 7 days, and it ran both GPUs just fine.
I went to 6-day test, and it ran both GPUs again and then stopped on the second GPU stopped again.

So, no lower than 7 days of extra work or it will just stop working on the second GPU.
