How to extend the iMac Pro to X99 [Successful Build/Extended Guide]

[JamesKI]

@ywz306 I have the the Asrock X99M Killer 3.1 motherboard. It does work pretty well with High Sierra, some caveats about it, KernelPM can be unchecked but xcpm_core_scope has to be enabled. I could provide my EFI folder as well as a modified BIOS, disables Lock Chipset, MSR Lock Control and a few other tweaks like power management C* states and updated Microcode. If you are interested in trying that let me know I can prepare it up for you. Now regarding your CPU looked at intel's site they dont show a E5-2675v3 but they do show a E5-2670v3. I can modify the TSCAdjustReset.kext if i also know your core/thread count.

thank you very much～～

BTW.. you just need to download the truncated 15-port XHC USB kext of @JamesKI James-Asrock-X99M-Killer-3.1-iMacPro-XHCI-15port.kext.zip for your motherboard, implement it in your EFI-Folder and disable the USB port limit patch in your config.plist. By this, USB should be fully set on your system.

Good luck,

KGP

hello，this is kext 。it has 16core/32thread。
i don‘t kown if tscadjustreset.kext and voodootscsync.kext is necessary

hello，this is cpu information

i have 2 question could you share your bios setting for me thank you


and，I can’t unlock MSR 0xE2 register 。it have no CFG LOCK option

this is x99m rom。and my Microcode Updateed rom

Hello, can i have ASUS HYPER M.2 X16 CARD V2 on X99-AII board? If so can i do a RAID 0 on it on High Sierra?
Thanks

Attached is the modified BIOS I had described in my post.

There is no CFG Lock in the Bios, just Lock Chipset & MSR Lock Control.

Extract the bios and put on a USB Stick that is fat32 partition. Reboot and it should be F6 to have it launch the flash utility.

I have modified the BIOS with the proper defaults for use with MacOS. You can change whatever you like, but those are the defaults that I use.

Only use a properly adjusted tscadjustreset.kext and forget about voodootscsync.kext. Never use both files at the same time.

hello, can you help me to find where is wrong in my setting ....
@JamesKI @kgp

what is this ? IOUSBHostDevice ....

I want to active all rap panel I/0 usb and drop all connector usb

@ywz306 Here is my entire EFI folder, replace your's with mine.

Then open up Clover Configurator, select the config.plist, you will need to generate a Board Serial Number, System Serial Number & SmUUID as I have removed mine from it.

Also replace my TSCAdjustReset.kext or edit it to reflect the proper IOCPUNumber from my 11 to 23.
Edit the proper CPU renames ie CP00 to PR00 to match those of your processor, look at this guide for information on this. What is already configured and enabled may work, but since I do not have your exact CPU I cannot lay truth to that claim.

You will notice that WhateverGreen.kext is not in my EFI/kexts/Other folder. I do not need it for my 1080TI it actually works better for me without it.

I did leave the USB KextsToPatch enabled but that should be able to be disabled.

Also if your CPU is Haswell you will need to change the FakeCPUID from 0x040674 to what properly matches yours. I don't have the exact FakeCPUID in front of me to add to this atm.

Other than that I think it should cover it. So by using my BIOS, and EFI folder with modifications for your CPU, etc. It should work without issues as it works perfect for myself. I also believe my SSDT's in /EFI/ACPI/Patched *should* work without any edits. I also noticed no performance increase on my system when I enabled the xcpm_peformance_patch so it is disabled by default as my system from benchmarking shows having it enabled lowers my cpu scores.

could I asking the last question。。。

about，audio‘ssdt config。。。


I used applealc.kext,liu.kext,codeccommander.kext.and audio is work
but hdmi/dp ‘ audio don't work

I try SSDT-NVIDIA-james.aml/SSDT-X99-Nvidia-kgp.aml and acpi-dsdt，and kexttopatch
hdmi/dp‘s audio don’t work too。。

I use jameki‘s ssdt，and don't work too。

my question is
1、how to config ssdt
2、and where to study？
