Is there a way we can we just add the necessary instructions to the existing config, to mine 2 sets of devices? I can get help with the above instructions in a day or so, but if this is a common problem maybe adding a run.bat or config file that can be adapted to 2 sets of GPUs on one rig. I'm just thinking out loud here in my ignorance. Forgive me if I am out of line.
I think what you want to get is rather easy to do:
Just create two identical profiles in user_config.json, one with "DEVICES" : [0,1,2,3], and second with the other cards. Name one "PROFILE1 and the other "PROFILE2". Then the only thing you need is to do a copy of the run_miner.bat and edit them, so one points to PROFILE1 and the other to PROFILE2. Then double click both and you are ready to go

Thank you all for the help. I have managed to set up two folders. One JSON has the DEVICES set to 0,1,2 and the other JSON with DEVICES 3,4. The run_miner.bat is the same for both. They both work individually and sometimes kinda work together. It seems I need to better distinguish one from the other for both minners to run concurrently at full speed. Whichever one I start first runs satisfactorily the next will be half baked at best. Any ideas? Lolliedieb said to set one as PROFILE1 and the other as PROFILE2, but I don't know where to put those two markers. Thank you all for your assistance.
