Enabling AMD RX 4XX cards in Sierra.

[Gigamaxx]

Hi Gigamaxx, have you tried two RX 480 cards at the same time? In my skylake system I can boot with one card and it works fine. I was trying with two identical cards but I get black screen at the end of the boot..

Try inject Intel and not injecting ATI. There is no crossfire support in OsX but you can double your open CL scores/performance in apps like Luxmark Ball benchmark.

this is an old bench with 2 RX 480s

I have 10.12.2 up and running. This time I have gone clover modification method. Have followed the steps as per carpentryplus25 post 272. And I have also patched according to Mork_vom_Ork's clover patch. everything's working well. Now it shows rx 480 8gb, and acceleration works but luxmark shows only 16 cu active. Do I have to do something else to make more cu active?

My rx 480 running good with blackscreen boot way, but now I can't boot with my hd 530, even the power pin of rx 480 unplugged, my pc won't boot up with my hd 530. I need to instal windows, and get dual booting, and now I need to change my bios setting but my Pc wont boot into bios with hd 530. Help me, what should I do?

To install windows, just change "init display" to auto or pcie in bios and unplug display out from motherboard and connect it only to graphics card. You will have boot screen and graphics card also. No need of removing the graphics card power.

Disconnect your Ssd/hdd and boot it should clear and go to bios screen. Turnoff plug drive back in and boot to bios by pressing " delete" key during start up

Hey gigamaxx, I have patched clover plist as on this thread - post 272, and that clover patch by mork_vom_ork. Gpu works alright but I can't get 36 cu active, only 16. Do I need to do something else? Also fcpx 10.3.1 is crashing at start now, in 12.1 , I followed your guide and fcpx was working well. Are you facing similar things?
