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

@PedroJSkywalkerAre you kidding me? Where is your multiplier on 44 ???
Most of your settings are still on Auto...even the voltage I said you have to change!!!

He did say that this is on old txt file and the new cpu setings arent in it. however i believe he probably only set voltage and not other settings.

 

[PedroJSkywalker]

In my previous message I indicated that the only thing missing was the change in voltage since I did it as a last test and did not save it on the pendrive.

The multiplier is CPUID which tells me that it is at 44.

Please can you tell me what I should change in the Bios, do not get angry please, I do not have your knowledge.

google, "how to overclock cpu" and just use stock settings.

 

[PedroJSkywalker]

I am very sorry that my ignorance has angered him.

I feel bad about myself but I do not know what exactly to play in Bios so that Logic works properly, if someone does not tell me what to play I do not dare for fear.

Introduction:​

From the very first boot on with my 7900X, I recognised that the new platform (2066) acts totally different in comparison to the X99 Build I had before...

No matter what you do with it and like it always is and always will be on a new platform - you will have the teethings.


The teethings can be big with X299 - I don’t wanna count them all here now.
Some of you guys will not have any issues at all and some of you will be in a really shitty situation.

It depends on your Software/Hardware which you use on it at the end of the day.​

Logic Pro X is one of the problem Software.

The problem with X299 and Logic is that It doesn’t use all cores... It seems at the end like it is this way.



But why ?



The problem is not a NVme drive, even if I found a guy, who get rid of this problem as soon as he removed the NVme drive from his setup.



The problem is the ASUS X299 Mainboard and the new Microcode inside of it.


THE PROBLEM:

If you use your CPU with stock settings (Auto) some Programs will not perform as they should,
the problem is that the Mainboard sends more and sometimes less Vcore then the CPU needs to clock higher.
In the case with Logic Pro the CPU will not get the Vcore it needs and now guess what it does:

It just down clocks and limit Logic to only 1 core with minimum Vcore for stable use.

How can I fix this?

Simply just set all CPU Settings manually and you are good to go.
For best performance I recommend to run cinebench together with CPUID in Windows
and watch the CPU Clocks and the Vcore Voltage it has under load.
Notice it and set this Value in Bios and go from there down.
As an example:

Your CPU is running with 1,190 Vcore
go your way with 1,185 Vcore and even more down until the Computer doesn't start anymore.
As soon as the computer doesn't boot make a CMOS Reset and use the last Vcore setting which worked for you and also did not loose performance points in Cinebench and thats it.
You will get the performance your CPU should have and also it will run cooler then normally.

Recommendation: Always save the last Vcore Setting as an CMO File to an USB Flash Drive.
You will thank me later

PS: Don't blame me or us if you make mistakes.
THE GUIDE IS NOT RELATED TO THE PROBLEM AND WE ALL SHOULD CONTACT ASUS US.
I will wright something on the weekend and also release it here.
Would be nice if we all would just send a copy of the text to ASUS and hopefully they will fix this.​

Sry. But this simple is not the issue. Logic is not being restricted to one core usage, and the boost not happening is not because of to much or to little voltage being applied. And I would advice all users in here that has not done manual overclocking before to not doing this supposed fix in any kind of rush.

To much voltage can hurt your CPU, especially these CPU's that have a tendency to run very hot if their not delided.

In your test you are using one of the simplest Synth Logic has to offer (AnBasic). And you scale it over all your cores with many tracks. My bench (attached here below, NOXCMP.zip) is instead focused on getting one core to accelerate to handle single threaded load in Logic. When this happens the CPU frequency should peak on all cores to accommodate that core load.

If you have not already started eating your holiday food Please show how many Bas Amp plugins you can run on the single channel in this logic project and show your CPU clocking up to max frequency to accommodate this.
Then pause and see the CPU going down to idle again, and staying there.

This would prove that your setup differs from ours.


Sry to be pessimistic here, and I really appreciate you looking into this issue!!

On a more positive note:

A couple of pages back I said that I would order a WIFI-card from amazon.de
It arrived today, and it works great!
This is a good solution for anyone living in europe!

Attached some photos on it and the logic project!

From what I understand I must look for the multiplier in Bios and set it to 44.

@olofd : Am I the one who find the problem and exactly know what the problem is or you?
My fix is more a workaround for the main problem...
Main Problem is called Hyperhreading which is not working at all on all Skylake X CPUS if you use Auto Settings.
Intel made some big big mistakes with rushing the release of Skylake X and ASUS also can't fix it at the moment...
The error by itself is in the microcode...
Also the way @kgp and I described is safe as long you don't do anything wrong.
THE VCORE on Auto is save for your cpu if you don't overclock.
By setting the Multiplier/Vcore Manually you don't do anything bad then give the cpu the Multi/voltages it needs

Just by the way the file I used for testing was I file which uploaded one of the users here and I did copy tracks until I was tired of it...
Did the same with my Cubase Pro 9.5...
So 295 Channels with Spire are also not enough proven...
You wanna tell me I lie or whats your problem?

I'm not saying you're lying. And you might be correct about the micro-code being wrong.
Can you please post some documentation about where you got the "ASUS also can't fix it at the moment" from?

I did not know that there where any known HT or boost-problems with this platform, maybe others knew?
(And if so, this should be clearly stated in the guide)
The thing here is that windows seems to work perfectly!

And btw. I never had my VCORE on auto. I know a lot about overclocking (Even been doing LN2 in the past).
I Always dial in my overclock/under-volt manually, that's why I know that there is no difference, at least for me,
in Logic by doing this.

And, as I seem to have to remind KGP about: Please, Please, Please. Keep a positive attitude and stop accusing and screaming at people here. Way to much of that in this thread already.

I'm NOT saying you are lying, all I'm saying, from experience is that VCORE, HT should really not be the culprit of this issue and I see no difference what so ever when doing things manually vs auto (Except for things that one would expect). If it turns out to be, I'll be the first one to applaud you!

@kgp
Do you agree with this statement then?

"Main Problem is called Hyperhreading which is not working at all on all Skylake X CPUS if you use Auto Settings."

For me it seems to work perfectly in Windows.

 

[PedroJSkywalker]

I have been reading and if I am not mistaken, the values that intervene in the multiplier are the following:

All core ratio limit
Min. Cpu cache ratio
Max. cpu cache ratio

If this is correct, you should put the limit at 44, the minimum at 12 and the maximum at 44 again.

Could someone tell me before doing it if what I'm going to do is correct?

 

[PedroJSkywalker]

Limit 44

Min : 28
Max : 28

Thank you very much, I'm going to change the values and try Logic.
