Hello,
Im having trouble running with 2x XFX rx480 4gb on z170 A pro MotherBoard (2x x16pci) on ETH
When i run ONE card using lolminer i get 19-20mh
--4g-alloc-size 4248 --keepfree 8 --devices 0

if allocation size is below this value, i get a joke hash (2-3mh)

As soon as i put second rx480 here is what happends

Card1: 14-15mh
Card2: 4-5mh


Set Gen3,
bove 4G decoding: enabled
driver version  adrenaline 20.11.2
Windows 10

Im using windows, booted from m2 drive on motherboard, is it possible that it makes a conflict, will switching to linux help.
Never mined in linux before.

Thanks, kind regards
