I have a problem with dual mining. I have 6x MSI RX 570 Armor 4G and i get totaly 170 mh/s and its keep going stable. When i tried to dual mining its going to about 140 mh/s. While im watching always 1 GPU decrease its mh/s and its always changing all of the gpus not just 1 GPU.
And also i have 5x MSI RX 570 Gaming 4G this machine working stable while dual mining. There is only 1 different between the machines i didnt update ethos the latest update because i want to use auto fan option.

Using a custom/modded bios? Which one? You're most likely hitting the power limit/voltage limit.
Anyways for the current BIOS you need to decrease the -dcri parameter in claymore config.txt or command line argument. You may use + or - on keyboard numpad to determine the best value for -dcri on the fly while mining to determine the best 2nd coin mining hashrate without impacting on Eth hashrate. Good luck
Thanks for your answer. Im using anoraks/oc bios. Im gonna try decrease -dcri parameter. BTW should i try without anoraks modes.
Anoraks bios are alright. (provided you flash the correct bios for your gpu). I am guesstimating in your case a -dcri value between 13 to 17 should be fine.
