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 ?
I thought about it, just an unfortunate coincidence that I decided to try on two free GPUs and they both Elpida, both ETH bios mod, on the ETH 470 gives 28mhs 1200/1900, 570 gives up to 30 on 1167/2050
