I’m currently starting to mine with PowerColor’s Rx 580 8Gb, but efficiency is breaking down in a few minutes and with that I have invalid shares. Here is my configuration without biosmod.
Fan 80%, Core 1150, DMP 1, VDD 900, Mem 2150.
It is currently doing 30 MHs/s, without changes to the board, could someone help me establish 100% efficiency?
