I run a GTX 1050 TI and after upgrading my system to a new dual GPU slot MOBO I would like to put my GTX 650 to work.

I am just a bit baffled as to how to edit app_config from BOINC's page to fit double GPU usage.

Can you guys help? I would love to put them both to work here.
I do have other projects that use the 1050, but at max peak load for a few seconds it reaches my 50%. The 650 is sitting idle at the moment.

Hi Greg_BE,

This problem is solved with a cc_config.xml line in your main BOINC Data directory. If you add <use_all_gpus>1</use_all_gpus> to the cc_config file between the <options> tags somewhere it should work. This may take effect with a config file update command, you may have to restart BOINC entirely, and sometimes it has even taken a full re-boot of the PC to get it to work. I haven't found much of a pattern with when cc_config changes actually take effect, but a full re-boot has always done the trick for me :)

Regards,
Kellen

Thanks.
I found a thread in overclockers that explains it all.

Yep! If you make a file called cc_config.xml (and make sure that it is actually an xml file and not just a text file named cc_config.xml) which contains the following;

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

and put it in your main BOINC directory, which for me is C:\ProgramData\BOINC, then that should work and force the 650 to be used.

Regards,
Kellen
