Hi all,

Anybody got two RX480s working in Sierra with full acceleration of both cards?

Going to be dual-booting and running a 1440p gaming machine in Windows on one side, but I need to run AMD Cards for OpenCL support for Final Cut Pro X video editing on the Mac side.

I know people have gotten one RX480 working, but wondering if you can get two working? Or, if necessary, if Sierra can use the first one and ignore the second? (ie. I'd just use one for Sierra but use the second in crossfire in Windows)

Thanks!!
Lucas

Right on!!

Can I asked which guide you used?

Also do you have any more than an 850 watt power supply?

Thanks so much,

Hi Lucas
I'm Korean. so my English not good :(
I understand your question but I explain hard to my building guide ...
I'm so sorry

my rig
i7-6700k over 4.6

two sapphire rx480 nitro oc+ 8g
and superflower 1000w platinum power supply

I think... 850w power supply is appropriate to using two rx480

No problem! Your English is not bad at all! :)

Wondering what set of instructions you used to get the RX 480s working. Did you just use this guide or was there a different one?

I am interested in knowing too. I'd like to add a second RX480 and would like to know how much work was involved in getting it to work.
