Thanks a lot for the updated mod, notbatman.

i confirm that RX570 4GB HYNIX is giving around 800HS XMR with 111W power of wall . i am running it with -95mv though, in addition to the default mod settings you shared.   Earlier max i used to get was  750HS @ 120W of wall.

I think this is the best 4GB can do. I didnt get a lot of time to test but trying with XMR. would keep you and all in forum informed.

Again, Many thanks for taking time to help me out.
