Mining ETN at nanopool with RX580 8GB , intensity 60 on each card 890h/s! Is there anyway I can further tweak it or that's the maximum? Do you guys have some BIOS mods for RX580 Sapphire Nitro+ Special Edition's with Micron memory for cryptonight algorithm? I am currently mining it with my ETH, which may be causing this not optimal speed.
