We're waiting for @luckyal. It needs to be tried on the Designare Z390 (which has a locked MSR 0xE2).
Changing a hidden BIOS setting isn't as scary or difficult as it may seem. I recently did it on my laptop to change DVMT Pre-Alloc. You can see this post for reference. I included lots of screenshots to try and make it easier to understand.

Now that's more like it!

Thanks, question to the moderators - are we getting way off topic on this thread? Should I start another thread and title it....?
I think you can continue this discussion in the Designare build thread. It can be of benefit to other Designare owners.

I share a screenshot of how the info IGPU - iMac 19,1 (9900k) Real is displayed.

Maybe it helps someone, or a simple curiosity.

The following is what my IGPU looks like. (I deleted WhateverGreen.kext) is no longer necessary for me.)
And everything works very well.

As I show in the following capture of the dump of a real iMac 19,1, the CPU-Type is "0510", therefore, the correct value that we should use in clover is CPU-Type: 0x1005
Could you share the ACPI and IOReg dump a real iMac 19,1 please? I would like to optimise the DSDT of my hack and I hardly need this dump for this! Thank you

Hey people here!

I'm planning a new build:

1. Asus Prime Z390-A
2. Intel Core i9 9900K
3. Sapphire Radeon Vega 64 Liquid Cooled (already owned) or Radeon VII

Can anybody briefly summarize the current situation about this hardware and iMac19,1 SMBIOS?

@MacintoshHealer
I'm really sorry, I can not share the dump, although I would like for everyone to perfect our hacks, but I promised the person who gave it to me, not share it or expose some sensitive and private information.
But if I can help you with something in the DSDT, I gladly help you, I use DSDT and I am currently polishing many things.
