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

[kgp]

I removed it and it starts to spin. But Change it to ISTAT MENUES? i don't get that

You are using HWMonitor.app, right? The latter has issues with the LPCSensor.kext and can strongly affect the performance of your fans.

If you want to use the LPCSensor.kext, use IstatMenus.app instead of HWMonitor.app!

You got it?

Thank you for your patience and thank you for your replies. appreciated.

I was checking my power management and in the IOREG I did not see the AppleLPC is that fine?
And in AGPM there is no NVIDIA AGPM.

AppleLPC?

AppleLPC?

I was going through some tutorials and it said if you have AplleLPC in IOREG you are fine with the power management.
But in-depth I don't know what it is.

LPCB not loadad or used on real iMac Pro..

Does your new config work on 10.13.4?

Does your new config work on 10.13.4?

Yes, but why you want to use 10.13.4?

 

[prince537]

I prefer to work on an official version rather than a beta build. Is your opinion something else?

The new iMac Pro X99 System

View attachment 333389


@nmano, my dear friends of X99,

I proudly present my new iMac Pro X99 System, which likely will require a new guide or a millennium revision of the current X99 guide, likely not leaving one stone at the other... No idea when I will find time to start with this major endeavour.

I am sure many of you will get scared by reading this...

The overall system configuration is now closer to my Skylake-X/X299 guide, of course with a couple of minor deviations (see files attached below). I finally also just added 10GB LAN and TB support.

TB hot plug tests still have to be performed. Else, I reached full TB support (TBEX 3 verified, Alpine Ridge not verified yet) including sleep/wake functionality thanks to the CPxx -> PRxx CPU core DSDT/ACPI config.plist replacements for the i7-6950X, which have to be adopted by means of IOREG for any other CPU different from the i7-6950X.

ASUS X99-A II TB BIOS settings:

With 10.13.5 Public Beta 5, patched BIOS Firmware 1902 for the ASUS X99-A II, and with the Broadwell-E performance kernel performance provided by @PMheart, I finally also have been able to overcome the recent Broadwell-E OC and performance burglary problem (see post #1692). If the latter patch is not valid for Haswell-E, @PMheart certainly can provide some specific patch in addition. Note that I also removed all other former xcpm patches (apart from pkg_score), as they have become obsolete with 10.13.4, at least for Broadwell-E. The same states for Pikes xcpm ssdt.aml, which has been substituted by a clover cpu plugin type injection.

You are free to investigate, wether or not PMHeart's kernel patch likely in combination with patched BIOS Firmware 1902 or in combination with 10.13.5 Public Beta 5 also solves the Broadwell-E/EP, Haswell-E/EP OC and performance burglary issue on Mac Pro Systems.

Carefully investigate the attached files, i.e. the entire actual EFI-Folder, the once more explicitly attached config.plist, SSDT-X99-iMacPro.aml, SSDT-X99-TB3-iMacPro-KGP.aml, the DSDT.aml, the iMacPro-X99.ioreg dump, as well as Apple's System Info dump, iMacPro-X99.spx.

Finally... we should decide if I put this current guide upside down or I publish an alternative guide within some new thread (likely in line with 10.14 PB1). Therefore, do not hesitate in providing feedback to your results, opinions and wishes.

All the best and enjoy and have fun ,

P.S.: Write down the number of this current post. It might be a very helpful resource for many of you.
I am just happy that tremendous hard work of several weeks will hopefully now find it's successful end..

Once more many thanks to @apfelnico and @nmano for their fundamental and important contributions to the SSDT development

I have changed my EFI folder with this and again my fan stopped working and i am using IstatMenus
