Newbie Help Needed
I am running dual rx 570 8gb cards but am only getting 18mh/s from each card. From what I read on other post it should be 25-30mh/s each.

Any ideas. Running Simplemining OS. Mining ETH

Have you flashed the BIOS, this will get you some more h/s, if not then try this for starters, use the 'one click' option (not sure if 570's are supported).

Note: Backup original BIOS first, this is most important.
