How to build your own iMac Pro [Successful Build/Extended Guide]

[warphead]

for those who can not accept that the performance in the audio programs is not as it should be I have a small solution it is not the fine art but it works

1) the bios settings must be exactly as they are described by KPG in the guide
2) put the core multiplier down in my case from 45 to 39
3) Undervolting the cpu with the help of cinebench you can find your lowest volt limit in my case 1.000v
4) Mount your EFI disk open config.plist and under Kernel and Kext Patches -> KernelToPatch Enable (xcpm_bootstrap Sierra © Pike R. Alpha) set to Enabled
5) Reboot

Attention show your CPU Temps if you have a god cooling solution you will have no problem

Attention the cpu is permanetly on his highest clock you set in the Bios!

I take no responsibility for any damage to the cpu

@kpg

forgive me for this post

@warphead : Did you mean this <89d804c4 3c227722> to <89d804cd 3c227722> ?
If yes its in there from the beginning...

Not needed with 0x0506E4 under 10.13... please perform XCPM checks detailed in section E.1), if you don't believe..

I can do it right now for you if you cannot be civil to each other.
I suggest you take a moment to read the rules.

i totally agreee, i appologize for my acctions and they were only as a result of being attacked for asking a question as @kgp has frustration towards other users its not fair for it to be taken out on me.

yes and yes from the beginning (you mean the cpu frequency ? if yes, yes)

As I said this is only for those who really want a high performance until asus / intel brings a solution

but beware the cpu will of course be extremely hot

@kpg i now but the enabel makes the cpu evry time to full load

[warphead]

I still use this patch...

For real ? And with you the power management works anyway?
come we slowly closer to a solution

I've been hackintoshing since tiger... I highly doubt that you are any more of an expert than I am... But okay

@shael Please stop make a s#1t for nothing, even if you hackintoshing from 1945 you can be standard amator with
all new platforms, patches, or any new solution... It's not so important if you are magic Pro of commodore
but... what you can offer for us, which tests results, informations etc etc...
(in normal ambience ... like adult, not some underage person who scream with some things without value in this case)
and ... most next very important detail: You should respect Creator of biggest and best custom hackintosh guide in the world!
It's nothing offensive... try to understand and everything will be OK

PS:
@warphead ... I know... maybe I'm to sensitive with some details like this one....
but sometimes - I'm CRAZY when I see "kpg" at the place of "KGP" again and again

@DSM2 - Thanks a lot for that brilliant discovery with fixed IPG CPU PowerConsumption

your smily says more than a thousand words

Now the words :

1.) He uses a different FakeCPUID than 0x0506E4, i.e. 0x050654 ! The latter FakeCPUID indeed requires the xcpm-

bootstrap patch for system boot and to make XCPM work! However, 0x0506E4 does not require the latter patch at all.
​

2.) Now, when you use the xcpm-bootstrap patch with 0x0506E4, you apparently totally mess an else perfectly working XCPM

configuration, that's why your CPU always runs at max. load, which equals to a system environment without any cpu power management.
​

3.) He requires the xcpm-bootstrap patch to boot and to make xcpm work, whereas you destroy an already working xcpm

configuration by additionally implementing xcpm_bootstrap, which is not required at all.
​

I don't see any improvement or profund base that could come with the else quite dirty and confusing solution you proposed above. Please don't take it bad. It is really not meant in any offensive way.

Apart from xcpm_bootstrap, you propose anyway what I already actually propose in my guide. Thus, nothing really new under the sun....

Have a sound sleep, and nothing for bad my friend.

Cheers,

KGP

I don't understand how lowering the clock speed and voltage of the CPU will do anything useful? Also, how will this make it run hot? I fail to see how this will do anything other than lower performance.

Do benchmarks before and after applying the above settings to show us otherwise.
