sapphire rx 570 nitro+ OC 4gb

at the moment i push my hash rate from 22mhs to 27.5mhs.
i copy my 1750 stripe to the higher one and setz the points in simpleminingOS

- mem clock from 1750 --> 2200
- gpu clock from 1340 --> 1150

other ideas to improve performance?

- use a other stipe?
- use a complete other bios?

i are open for other things :-)


Best regards
Willi
