Just installed 3rd GPU - BOINC not utilizing it. I've been browsing the forum here and learned to create a config file, so I did. Stuck the xml file into the BOINC folder, closed the client and re-started it.

cc_config.xml:

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

but opening the advanced view and looking at the current tasks, I see only (device 0) and (device 2) - it's skipping over #1 still...

could use some help....
thanks :)

thanks :)

We could too. How about providing some information?

Lets start with the top 20 or so lines of the BOINC log where it shows which devices are detected, what OS you’re running and if it found the cc_config file or not.

Hi, Thanks for the help.

here's the info, and from the looks of it, config file is not found and GPU 1 is not used and ignored by config..

….and I found my problem....
config was in wrong directory was putting it in the

C:\Program Files\BOINC and not the C:\ProgramData\BOINC

Make sure that your cc_config.xml file is called exactly that. Windows has a habit of calling it a text file, named cc_config.xml.txt, but with the final three letters hidden.

Make sure that the file is described as an XML Document in File Explorer.

Edit - or put it in the data directory :-)

thank you for the help and advise :)
