I made custom bioses for:

4GB micron 14.5 Mhs with ETH/ETC

Tested on Sapphire RX560 Pulse 4GB


And

4GB hynix 14.6 Mhs

Tested on Gigabyte RX560 Gamming 4GB



Both mods stable and running for days. I'm willing to sell those mods for 0.1 BTC each  if anyone interested.

p.s. Speed is with current epoch so 135... It was actually a little bit faster.

p.s.2 screenshots will come later
