Hi,

I recently bought few MSI RX 580 Armor 4G OC hynix, after a few hours, I only got 23MH/s on ethash, which is really bad.
I tried everything I knew besides changing the motherboard.
The best result I got, is 23MH/s with PolarisBiosEditor1.6.4 one click patch.
Does anybody have any ideas?
Thanks
