I tried adding "FB NAME" in Clover for both "Kamarang" and "Iriri", and had the same results on both with regards to the video outputs. Is there anything else I should be adding to Clover other than the name?

Make sure Inject/Ati is enabled.

Following this with a lot of curiosity.

 

[dnetcrawler]

Ok, so Injecting ATI with both FB Names did not solve the issues on the other ports.
Here is where I'm at:

• OOB support for VEGA only one port. No iGPU and not patches required.
• Tried different VAGA FB Names in Clover to solve port issues with no luck.
• RX580 does NOT work without iGPU. Computer freezes when loading KEXT.
• With both VEGA and RX580 installed, trying to use VEGA as gpu helper card, the computer boots all the way but it goes into dark screen for both monitors. The mouse RGB is still on, so I'm assuming is not a computer freeze event, but a loss of video signal.

I have the vBios dump, and posted the outcome from different decoders.
I'm running MacPro 6,1 on bios, perhaps I have to do custom SSDT and put both graphics cards as GPU1?
Perhaps changing to iMac?

Any help getting this fully working, is greatly appreciated.

 

[dnetcrawler]

On another note. I did install this version of High Sierra with only the RX580 installed. It worked during the installation without and iGPU and without any Patches. I can get it to work without full acceleration if I remove all the AMDRadeonX* KEXT from the Extensions folder. Could this also be an issue with FB identity?

 

[dnetcrawler]

Ok, so I can confirm all ports are working on Vega OOB with full metal support on my ASUS Maximus IX Z270 with 7700k. No patches and iGPU!

I'm not sure what is going on with the X99 and the ports not working

At least you have a port working this may be fixable following @Mork_vom_Ork s port patching methods, its working without IGPU thats cool! You may need to use find and replace values to activate the other ports on X99 setup.

Can you run some Uningine Valley and Heaven benchmarks in extreme and extreme HD settings?

Geekbench compute with the 7700K.

Maybe it's an SMBIOS issue. Are you on different bioses between the two setups? Maybe it "knows" the X99 is only supposed to have a certain vid out, but for your 7700K (iMac?) it can use more than one.

Pure speculation..

Here are some OpenCL numbers.
