I have a Win10x64 machine with a GeForce 980 & 770. Both NVIDIA drivers and device manager recognize as installed and functioning.

However, BOINC is only using one GPU (the 980) for GFN. It should be using both right? Any ideas why this is? Using NVIDIA drivers 416.94

2 things to check Jordan

1) the <use_all_gpus>1 switch in cc_config.xml

and

2) plug a monitor into the other GPU (can swap the cable from the first GPU and restart BOINC)

Did the trick for me with my 1070ti and 550ti

Also check the event log in BOINC - it should mention the cards individually with a reason for non use

Thank you for the suggestions Dad.

Unfortunately still not working. I don't seem to have a cc_config.xml file. Where should that be located?

I've swapped out the video cable to confirm output on both cards.

Completely reinstalled BOINC.

Rebooted many times.

Still only 1 card crunching... :(

What does the client's event log say?

The config file should be located in \ProgramData\BOINC\ on whatever drive you installed it.

Yeah, it recognizes it alright, but by default BOINC only uses the most powerful card on multi-GPU systems. You have to tell it to use both. Create "cc_config.xml" with a text editor in the aforementioned location and put the following in it:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

I'm not sure right now if you can simply click on "read config file" in the client and it works right away or if you have to restart the program, but whichever is needed, it should work after that.

When I use BOINC MANGER -> OPTIONS -> EVENT LOG OPTIONS and hit "SAVE", BOINC creates and saves a default version of cc_config.xml if it did not already exist. The use_all_gpus option is down at the bottom of the file.

Yeah, it recognizes it alright, but by default BOINC only uses the most powerful card on multi-GPU systems. You have to tell it to use both. Create "cc_config.xml" with a text editor in the aforementioned location and put the following in it:
