This card needs a BIOS hotfix, there’s something fundamentally wrong with it on mining (it works great with gaming/etc).
I can get to 85w (on GPU-z) on pretty much any other card but this one, I’ve been using this with 1150/2100 (30 MH/S) but this one can’t go above 1100/1900 while using 100w at 27 MH/S. I’ve managed to get this one to 31 MH/s which is pretty good but the power consumption was 140w.
I have tried undervolting this card but it would just crash at less than 900mv while getting about high 130s.
What I know so far: This card comes “overclocked” if there was a bios who reversed the factory OC and made it so it works as a regular card, the power consumption would go away with good hashrates.
I have tried Elpida’s XFX RX 570s power save rom and it had very very low consumption on this card but it wouldn’t go above 20 MH/s.
Shared all I know, maybe someone can take it over from here as far as I know.
