I used miner 5.6.1.3.b5d on my RX 470 4GB cards that work in 1100/1900, and that's what I got:
x22i 2.33 Mhs
phi2 2.6 Mhs
lyra2Z 1.4 Mhs
allium 3.0 Mhs
P.S. After my last test, I reduced the power consumption of my cards by changing the BIOS, but even this did not prevent me from getting a good result.
