i try Claymore 9.8 -cclock -mclock, this is not stable, the memory suddenly drop to 1000mhz from 2200mhz , and then back to 2200 for few sec then back to 1000
I have the same behaviour in Claymore 9.8, also power is not stable. If not using -cclock -mclock I got stable 30.2MH/s for RX580 8GB and MSI Afterburned 4.4.0 beta 16 setup:
mV 970
core 1150
memclock 2150
