The RX 470-480 I believe is only capable of 4K 30hz with HDMI, 4K 60hz DisplayPort. No 5k yet and it may not have it in Windows either. Vega 10 should be coming soon (3-6 months) it should have 5k support since it's in Sierra I would imagine retina screens will require it.
Is that true also if you get a card that has 2+ Display Ports? In the same way you can get this working with a GTX960/70/80 setup?

@Gigamaxx - can 1st post be updated since we have 10.12.2 - I cannot comment on changes since I dont own any of the cards (or have a Hackintosh right now!)

@AnyOne - do any of the RX460s work fine when unlocked BIOS with extra Cores is flashed/enabled? I know AMD mess with the driver support in Windows if you flash the unlocked BIOS but in MacOS it might just be free performance without issues??

A member mentioned the update for the 460 did not work (Blackscreen), he reverted back to original bios.

The CU fix for Fury cards worked on a few RX 460 cards and improved benchmarks by about 20%

As of 12/3/16 Polaris 10 support is in Sierra Beta 4 version, and now there is Vega 10 (the new unreleased AMD card) in the AMD9500Controllerkext.
Does this mean that RX 480s and new Vega GPUs will work OOB?

Any forseeable issues with using a rx480 on a x99 motherboard?
(Sorry for all the questions, will be my first Hackintosh)

I got tired of all the NVIDIA bs and got an ASUS Strix RX460 4G (with 6-pin).
Flashed the bios using Windows to unlock the cores. Configured my Hackintosh and works like a charm.

If only I could get HDMI audio working, I would be happy.

Am I understanding this correctly, as in rx480 cards will work OOB with 10.12.3?

Very interested in this because I'm building a Hackintosh on a x99 motherboard and I wanted to use this card.

You will need a helper graphics card and one 16 lane pci slot and one 4 lane pci slot. If you can configure this in bios you can make it work. They're not OOb completely, you need to make a few adjustments but most are able to get them working and use them for graphics work. They along with the newer AMD cards need bios settings for igpu or IGFX as primary display, or integrated graphics mode. If you don't have graphics on you CPU you can use a lesser " native supported (OOB)" card as integrated graphics and it works. One user in the testing thread with an X99 system has a 1070 in slot one 16 lanes, and an RX 480 in the #3 slot with 4 lanes for the RX card. In Windows he has the 1070 and then when he boots into Sierra the 1070 lists as display 5mb, but the RX gets support and functions well.

I've tested this using my Z170 in dedicated graphics mode and it works, it's not as good as with igpu (CPU) and RX card it loses about 10% performance. However, z170 systems only have 16 lanes total so an X99 with more lanes available (CPU) dependent should work a lot better.

Need to point out that if anyone else is also experiencing similar problems. The current driver tends to crash game/whole system for me pretty often while watching html5 h264 content on youtube with hardware acceleration on. With browser eg firefox. And playing metal/opengl game at the same time.

So it would be safe to disable all hardware acceleration on card. In firefox about:config and media.hardware-video-decoding.enabled to false

And there was no difference between beta and stable.
