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.

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.
