Hello I recently got a new mobo and gpu the mobo has enough slots to run 2 gpu's so I put my old gpu in as well as the new one but boinc is only using the new gpu it sees both but only wants to use 1 is there a way to use both gpu's or would using lunatics be the easier way. The new mobo is a Gigabyte GA X99 UD3P with a Xeon E5 2670 v3,the new gpu is a Asus Strix gtx 1070,the old gpu is a Asus gtx 750 ti. Also here is a copy of the event log when starting boinc.

Hello again thanks for the info now since I will have to create the cc_config file since it is missing what all will have to be in it along with what I want sorry for my ignorance but when it comes to this kind of stuff I am very much a newbie but am willing to try to figure it out. Thanks.

CTRL+Shift+F



Just set/check any Log Flag (e.g. benchmark_debug) and cc_config.xml will be created.

Then edit cc_config.xml by Notepad to change 0 to 1 in line:
<use_all_gpus>1</use_all_gpus>

Restart BOINC
