Totally respect that, and x299 seems to be running well enough. And the xeon-platform is pricier. But native CPU-support makes a big difference in my previous experience, and is one of the things I really am looking for, even if that makes the price go up with 10%.

And my question regarding a build guide was directed to @rolandino that has this system, not to you kpg.
Well you directly asked me if I have any thoughts on that, that's why I responded. Please just allow me one further comment: who says that Skylake-X will not be natively supported by OS X? Following @rolandino not even the Xeon W-2155 is yet natively supported. Just be patient and don't force things.. there is really no need yet to draw such conclusions. We really have to see how things will evolve in the very near future. If then Skylake-X would not be natively supported, such comments or statements would be adequate. ;)

I switched it on. The timings are still the same at 16-16-16-36. the volts go up to 1.35 and the frequency is now 3600, but os-x still shows 2133.
I do have XMP 1 switched on in the EFI boot tab. Is there something else I need to do in the EFI?
Not really... Did you check "XMPDetection=Yes" in Section "Boot" of Clover Configurator? Although I do not even know if this entry has any effect at all...

In all likelihood, Skylake-X will never be officially supported by Apple. Fortunately the new Xeons will be "close enough", for the Hackintosh community to squeak by. The principle reason for Skylake-X being unsupported is that there are certain large corporate and government contracts that Apple seeks to maintain which mandate ECC memory; which Skylake-X can not support. Thats why the Mac Pro series has always used Xeons since moving to the Intel platform from PowerPC. I had a few problems with some of my large simulation data sets when I was running my SR-2 Hackintoshes which was probably related to the non-ECC memory I used, so I transitioned all that work to Ubuntu based servers with Xeons and ECC memory.

The Gigabyte C422 board looks quite promising for a Xeon Hackintosh build, just not sure I have the enthusiasm for taking it on.

As said this guide works for both X299 and C422, so there is no need for a separate guide.
I investigated the IOregs of the Asus Prime X299 and the Supermicro C422. They are identical in many parts.
Again thank you for your work @kgp

Most likely the Skylake-X CPUs will be natively supported.

Did anyone try the HWPEnable flag?
For me it did not work, same issue when dropping FakeCPUID...

Nope and honestly guys, me personally I am not deeply interested in this 3rd party soft- and hardware audio developer issues. I basically use onboard audio hardware, iTunes, Youtube, photo-, audio- and video editing etc... Else I record at most myself playing my acoustic piano... ;)
:) so for me its fine if i use Sierra i am happy :) i can change later to 10.13.xx, for Audio Workstation is it anyway best to put on the previous OS version, so you have no problem with alle the audio soft and hardware compatibility.

Sorry, some Skylake-X processors already nearly perform natively and therefore also seem to be close enough to the future iMac Pro processors. However I did never mention that Apple will ever "officially" support this CPU type. I am also aware that Skylake-X does not support ECC memory. :thumbup:

The rest already has been answered by @rolandino above in post #2214.. ;)

I'm also running the 7820x with no fakecpu on 10.13.2. I'm getting these results on Geekbench, which I guess it's not bad.
Thank you for the awesome guide kgp!

By the way, just until now, I was getting random reboots ~1 minute after booting (and I run the Intel Power Gadget and temps seemed OK). I saw no Kernel Panic errors or logs (even with the debug flags on clover). I don't know if it was Lilu, or what could have caused this (I compiled Lilu from source as I saw that it could cause some issues). To be honest I'm a bit scared to restart in case it becomes unstable again... It's running now for ~1hr and I'm doing intensive tasks...

Which version of Lilu and Lilu plugins are you using?

I built them from source so they should be up to date (I read there was an issue on 1.2.1). The only plugin I'm using is the NvidiaGraphicsFixup one.

I just rebooted and started to get the random reboots again :(
