Ok making the testing the Radeon VII with an Core i9 9900K overclocked to 4.7Ghz, 32GB RAM DDR4 2400Mhz dual channel, Mainboard Asrock Z390 Pro4. UHD 630 is active in headless mode but with the KabyLake ids Fake_id 0x59128086 and idgplatform 0x59120003. I am using Mac OS Mojave 10.14.5 Public Beta 1 and is more way stable that the X299, Final Cut is not restarting the computer like in my X299 machine and the performance is really good, I made a Bruce5K test and the render was done in just 6 seconds.
I am still downloading more software to test it but until now is working way a lot better than the X299, I am using for 5 hours now and no lag at all that some users wrote, no blackscreen it is working without having to iniciate with the igpu first and later move to the Radeon VII, in my case is working directily from when I turn it on until I go to the Login Screen... like the other supported Radeon GPU... I will test later multimonitor with an FullHD and a 4K monitor to check if all ports are working...
