RX 480/ 470 FOR LBRY COIN

hello friends, I need help.
you can extract Lbry with RX480 / 470?
I can not, I get low-hash,

1st rig - 4 x RX 480, 1x R9 390X OC triiXX.
2nd rig - 2 x RX 470 Nitro OC, 1x R9 390X OC triixx
I tried everything, Genoil 1.1.6, 1.1.7,
16.7.1 driver, - 16.7.2 - 16.7.3 - 16.8.1 - 16.8.2, the result is always the same, low hash,
I also installed win 10 anniversary, but to no avail,
so I got nervous and I deleted everything.
can you help me?

where miners used?
you use drivers?
Use configuration?
you have one of your configuration files BAT string to paste here? so I can copy it?

thank you in advance
