Disman are you running two instances or one?
How to run two instanses?
Copy folder with miner and start from two locations.
It is enough just to run it twice. No need to copy anything - for EWBF. For nicehash miner you can run two instances in one program from the .bat file using this setting for number of cards "0 0 1 1 2 2 3 3" = 4 card, each two instances.
