Hi everyone! I think I found best oc settings for RX 570. I have 2 MSI Armor RX570 8G with micron memory (BIOS Modded) and I get 4050 kh/s for each. Stable for 2 hours and no memory error or stale share. My overclock settings: 1268 Core - 900mV and 1750 Mem 900mV (--opencl-threads 2 --opencl-launch 21x128). Maybe I can downvolt a bit later.
