Okay  you got a r9 390  and low and behold you scored a hard to get rx 480.

You want to run the cards on your rig.  I am getting really good results.

With amd 16.7.2 and with Claymore dual miner only eth coins.

BTW eth is over 13 usd a coin up up and awayyyy!!!

Give me time to set this up.

I self mod but I almost never delete.

so here is my mixed rig.

1 r9 390 with 1 rx 480

a gigabyte b75m mother board
2  4gb sticks of ram
a silverstone 700 watt titanium psu
a corsair case? Don't remember
case fans are silverstone 141's
cpu  is intel i5 2500t
 got to check this as I can not remember since i have a few pc's

this shows I am running around 56-58 mh with the two cards


power is from my 240 volt pdu reads 2.1 amps  so 504 watts.

I have overclock the r9 390 hard.


the rig is in the closer case


overclocked  r9 390   and   stock clock rx 480  (power limits at -28%)


So use amd 16.7.2  go to amd settings and click gaming




next click Global Settings



this brings up the r9 390 and the rx 480

All GCN AMD cards can be mixed and mined with without issue. I've mixed 7950/7970/280x/290/290x/390/390x/RX480 all without issue. It's nothing complicated.

That said, I prefer keeping similar cards together.
