EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal 0x9a0ed4f7a64a4c3e5d2e5b7672e585c0bbea1bcd.Frankenstein/faustasd@outlook.com -epsw x -dpool stratum+tcp://pool.unimining.net:5770 -dwal D7smhMa6RQYTtX8WyfB3s829doEojRV8wT.Frankenstein -dpsw x -dcoin blake2s -allpools 1 -dcri 30 -asm 2 -mode 1-02 -mode 1-03 -mode 0-00

SET TO NOT MINE DUAL ONLY ON GPU2 AND 3 WORKING LIKE THAT
