Hello @Claymore,

I have problem with rx 480 and r9 nano running together. I tried driver from 16.9.2 to 17.5.2 without success.
R9 nano is not wotking with default settings, but it  give 340 H/s with -asm 0 -a 2.
When I use 15.12 driver without rx 480, it give 430 H/s.

Can you please advice in this case?
