very low hashrate on ETH for Sapphire Nitro+ RX580 4GB Elpida

[Omarko]

As the title states, I am getting very low hashrates for Sapphire Nitro+ RX580 4GB Elpida memory chips.

Stock out of box it would do 18Mh/s, after doing the BIOS mod and copying 2:1500 to all below it stayed at 18mhs. After overclocking / downclocking core clock at 1200 and mem at 2025 I get 20 Mh/s.

I am using ethminer, Windows 10 and 17.11.1 drivers. When using simplemining USB stick I get 18mh/s

any ideas what I can do to get better hashate pls?

EDIT: I reinstalled the blockchain ATI drivers and now getting 24MH/s with the above mods. Anything else I can do to get closer to 30 ?
