Hi !
So, I have a little problem with BOINC
I have two GPUs in my system (a GTX 1060 6GB and a GT730 2GB), and my problem is that BOINC only use the 1060, how to force BOINC to use only the GT730 ?
Because the 1060 gets really loud and I have to stop BOINC when gaming (I'd like to let it run while I'm playing game, hence why I want it to use the 730, and use the 1060 for gaming)
Does anyone knows how to do this ?
Thanks :)
I'm running Windows 10 1903.

You can configure BOINC to do that. Full details are in the Client configuration page of the user manual.

First, create a configuration file cc_config.xml

The easiest way to do this is to make a temporary modification to the 'Event log options...' - Ctrl+Shift+F from BOINC Manager. Change something, save it, then change it back again and save it again. That creates a complete configuration file pre-populated with all the standard options.

Then, add an extra line to it, using a simple text editor like Notepad. From the manual:

<ignore_nvidia_dev>N</ignore_nvidia_dev>
Ignore (don't use) a specific NVIDIA GPU. You can ignore more than one. Replaces <ignore_cuda_dev/>. Requires a client restart.
Example: <ignore_nvidia_dev>0</ignore_nvidia_dev> will ignore the first NVIDIA GPU in the system.

You want to follow the example exactly, because the 'best' GPU - the noisy one you want to disable - should be device 0. Put the new line in the <options> section, in alphabetical order. [It'll work anywhere, but keep the file organised - it'll be much easier to remember what you've done in the future]

Save the file, and restart BOINC. Check the first few lines in the event log on restart to ensure that the change has worked properly.
