rx 470 4gb and rx570 4gb elpida about 2.5-2.6 hashrate
tried different memory and kernel frequencies less or more - nothing changes how get 3.3 mhs ?

You no it must be elpida memory cause I get the same hashrate with my rx570s but on my rx470s samsung hynix and micron I get 3.2 or 3 but on my rx470s I put the stock bios back on my 570s have ETH bios on them
