I updated my rig of two rx480 xfx to mine eth using hiveos
Both into x16 slots
 
Z170 A pro Motherboard
1card 28mh
2card 7mh
Cpu intel 7500
8gb ram

Hash rates went up nicely compared to windows but i wonder if its possible to make them run both
How do i configure lanes property.
I can't make second Pci to run at good rate, swapped the cards which proved its not gpu issue

Ye man, sadly my windows is on m2ssd. possibly what takes some lanes away, and i use this deskop daily so sad.
I do mine with 1070ti around 29mh and rx480 around 19mh if single x16 is taken

But I seen ppl on group that can mine 2x RX4xx cards if there are two x16 slots (x8 x2) is it cause dag went up or..?

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

i have same issue, cant find solution,
in mining cmd there are regular hash values but shares seem to be 0 valid and 0 shares total
