Caution! AsRock Gaming Z370 itx/ac Not Compatible with VEGA 56/64!

Hi guys,
I spent four days of my life for update my perfectly works on High Sierra hackintosh to latest Mojave 10.14.6
English is not my native language, therefore full article will soon, but short version here.

My config for High Sierra is:
i7 8700K
AsRock Gaming z370 Fatality itx/ac
2x16gb Corsair LPX 3000Mhz
GTX 1080ti Aorus

I know that Nvidia not compatible on Mojave+. Therefore, I bought Sapphire Vega 64 (reference design). For last 4 days, I also bought Sapphire Vega 56 Nitro+, Sapphire RX580 Pulse, Sapphire RX 570 Pulse itx. But my motherboard not works with no one Vega. I can't enter to BIOS. Almost all the time, I got black screen. No matter HDMI or DP. I need 20-30 restarts to do it. I try Enable/Disable CMS, but nothing. In those few moments when I get access to enter the BIOS or load the Clover system was unstable, Always lags and looks like GIF animation. But, when I plug in the RX580 or RX570 or my 1080 Ti, system works well.

All GPU works well on my past PC based with i5-4440 + AsRock Z97 Pro4. All Vega cards works perfect with WEG and Lilu kexts.

How i have 2 boot partitions. First – High Sierra with 1080 ti, Second – Mojave 10.14.6 with iGPU UHD630. For changing need to change primary GPU in BIOS setup.

You're doing something wrong.
I have this exact board and Sapphire pulse Vega 56. All works just fine.

9700K it's not 8700K, but I know that it's Coffee Lake. What bios did u have on your board? What about CMS?

 

[ownliwon]

CMS disable. bios 3.10

CMS disable. bios 3.10

I bought this board with 3.3, tried 4.0 and 4.1.

12 days have passed since I wrote a letter to AsRock support. Nobody has answered me so far. I have already decided not to buy more boards from this company. So it happens. You have been using the company's products for 8 years, and then you buy a hi-end board and understand that support is fully-****. Bye-bye AsRock, and hello Asus.

I use this same motherboard with a Vega64 without issue. I think my BIOS is still 1.1 and I have used the i7-8700K, i3-8100, and the i3-8350k. I am nervous about using a newer BIOS. Many of the newer BIOS have issues with hackintoshes it seems. This is likely your problem. See:

FIX for boot hangs after BIOS update (ACPI PATCH)

This is an ACPI Patch for the people who update to the last bios and can't boot. My board is the MSI B360A-Pro and has the latest bios 7B22v27. First add the patch (the blue line from the picture) to clover config, then apply the Bios update. To easily add the patch using terminal, read post #48
