Hello guys, any of you tested MSI RX 580 Armor 8G OC HYNIX ? I can't do more than 27 MH/s with straps 2:1750 and OC 1150 / 2150.

Did all straps like 2:1500 - 2:2000 = crashing after Windows booted up.
2:1625 = with stock setting crash after miner starts work.

1:1500, 1:1625, 1:1750 = no effects at all.

Any ideas? Or I'm doing something wrong?

Or this is gabage gpu and mems? I could return them and try with something else. What you think?
