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

[juantrix]

Please help
Some recently KP... I supposed to be the non pached bios 1301... so go back to 1201. But Today only viewing a video in Safari (Crash).
CPU Temps over 30 C, GPU over 38C (fan less), XMP profile 3200Mhz... Recently cleaned my system with Onyx... What can I do?

128GB of RAM slows down your post time. Even at the speed of light, it takes a while to check 128GB of memory. I have that problem with my MacPro too.

I have 128GB of RAM installed, can't say I've had bad post time...

However, lately (and not sure if that's due to the new BIOS) there are times where it will hang on the Asus incredible logo at startup. Have to press reset when that happens

I've done like you now, plugging the H115i fans to the motherboard... Im not sure I'm seeing any differences with temps, except that now my machine is far more noisy as fans go full speed when 70C is reached ; something that happens very easily in my setup...

Despite the fans running at twice the speed , the temperatures appear to stay in the same ranges when I compile my project (around 80-83C)... At the expense of noise.
And the VRM temps are still just as crazy, over 95C after 10 minutes of compilation going, and that's with all 6 fans in the case blowing like crazy.

So maybe not worth it in the end.

New e-mail to ASUS

Dear Olga,

Many thanks for providing the possibility of a manual MSR 0xE2 register unlock within
PRIME-X299-DELUXE-ASUS-1301.CAP.

However, please fix the unsynchronised TSCs of Skylake-X cores on boot and wake from
S3 at your earliest convenience.

Something in the BIOS still screws them up, as it is clearly seen by the none null state 
of the TSC_ADJUST register.

Many thanks in advance,

KGP

Followed the instructions to the letter on creating a USB stick. When I attempt to boot from it I get the Clover screen but when I attempt to start from the USB stick I get the following errors and the PC shuts down. First picture with slide=0, second picture without slide=0

Nice one kgp! Does 1202 Have the same issues patched? or 1301 patched?

Directly jumped from patched 1102 to original 1301 + TSCAdjustRest.kext.

All individual original BIOS firmware distributions yielded unsynchronised TSCs, an issue that only could be removed by firmware patching.

However, as 1301 allows to manually unlock the MSR register, the available patches are some kind of overkill. As there is no separate patch available to exclusively fix the TSC issue, I simply use the unpatched original firmware in line with TSCAdjustRest.kext for now.

Probably a dumb question @kgp but were you / are you going to update your initial page with this change in the files as it seems we no longer need patches to unlock MSR? This is assuming that this isn't a one time bios version from ASUS with the possibility of them re-locking it for future bios releases

About MSR 0xE2

I see on documentation that bios on Msi mainboard allows this option :

CFG Lock Lock or un-lock the MSR 0xE2,
CFG lock bit.
- [Enabled] Locks the CFG lock bit.
- [Disabled] Un-locks the CFG lock bit.

This option is useful for building iMacPro but I do not read on the previous posts that someone said about it?

Asus implemented the manual MSR register unlock option on my user request. Why should it be a one time Bios version?

I will probably update the corresponding guide section once ASUS also fixed the remaining TSC desynchronisation issue.

Until then, patched BIOS 1102 is still a serious option.

It is a feature well known to all MSI and ASRock users.

Gigabyte mobos anyway do have unlocked MSR register by factory default.

The MSR register of all ASUS boards however was locked for ages. The fact that now we are also able to manually unlock the MSR register on ASUS mobos is indeed a major achievement and kind of revolution, which is totally at odd with all former ASUS strategies.
