I’m not an expert but im curious and I’ve the same type of memory(micron) in my cards but mine are Msi armour 8gb.
I’ve the current settings on hive:
Fan 65 / Core clock 1250 / dpm 4 / V 900 / Mem clock 2250 / mdpm 2 (or nothing it assume the max in some cases) / Ref 240
this at 82w per card on hive and I could reach between 33.5 and 33.7 Mh on claymore dual v14.7 mining ETH cards at 57 / 58° C
Good luck with the playing with settings everyone
Edit: 1d 5h mining 1 wrong share with the rx580 anyone have something that can improve this settings please?
