I have 3 GPUs installed. 2x 1080 and 1x 980.

Both 1080's are crunching fine but no task is being downloaded for the 980. I noticed on the computer page the 980 isn't even listed as being on that machine. However, on my PC the NVIDIA driver (using the latest) does show the 980 as installed and I am using it to power one of my displays.

Max # of simultaneous PrimeGrid tasks is set to No Limit.

Any ideas what might be going on here?

When BOINC starts, what does the event log say? Does it see all three?

Also, BOINC will exclude significantly slower GPUs by default. It is not clear what "significantly" means. To override this behavior, put the following in your cc_config.xml:

<use_all_gpus>1</use_all_gpus>

You may need to restart BOINC after that.
