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

i have a Question about the PCI-E Slots on the Prime X299-Deluxe Mainboard

The same on 10.12.6 and 10.13.2
PCIE x16_1 --> VGA Card
PCIE x1_1 --> behind the VGA Card
PCIE x16_2 --> Kernel Panic
PCIE x16_3 --> Work Perfect
PCIE x1_2 --> Work Perfect
PCIE x16_4 --> Kernel Panic

Try with diffrent PCI-e cards

befor i try a big journey to solve the problem, its posible that this 2 pcie slots with kernelpanic never can ben used ?

So? You see that e.g. your GPU SSDT-X299.aml implementation does not work properly. Try to improve with the help of IOREG

OK，thanks a lot

Which PCIe adapter you intent to use in PCIE x16_2 and PCIE x16_4?

Please see related info in the Prime X299 Deluxe user manual, page ix, Expansion slots!

 

[warphead]

Which PCIe adapter you intent to use in PCIE x16_2 and PCIE x16_4?

i use
1x RME RayDAT (Audio Card)
1x UAD 2 Octo Core
1x UAD 2 Quad Core

i have tested diffrent combination but it works just in the 2, PCIE x16_3, PCIE x1_2 in the other slots the RME Raydat wont work but macOS boot and UAD make kernel panic.

If you look at the OLED picture of @Rulebreaker01, you see "Code A1 - Detecting memory"... Thus, if this picture was taken at the same instance with the QLED 00 error picture, I would not exclude that easily a memory issue. Maybe simply some RAM module might not be plugged properly. Up to my knowledge, QLED Code 00 appears if any component cannot be properly initialised, including the memory modules. Of course it can be also a malfunction of the mobo itself. In any case, further details to the apparent issue are delivered by the OLED Display!

Hey man, what was the PS you were using before with your 7800X? The code showing on the OLED is AF, not the A1 (sorry for not to clear while taking that photo), and I am thinking could be PS related..
Thanks man,

When I started the installation of Windows I came to the window to select which disk I want to install it, previously I opened the console and with clean diskpart the disk in which I want to do the installation that incidentally is a Samsung evo 256 GB SSD, then the window in which
starts the installation of Windows but does not even pass 0%, after a few seconds the message "The Windows installation detected an unexpected error." Check if you have access to the installation's origins and then reinstall the installation. 0xC0000005 ".

Hi Pedro:

I had similar problems when I was mixing GPT partitions with legacy booting (without Clover) and the other way around: MBR partition with UEFI booting. Windows is very picky about this and gives all kinds of silly error messages.

In addition, if you already have a GPT disk, the size of the ESP is very important. I think this is more relevant for macOS, but it is something to be aware too.

And a 3rd thing is what someone already told you: having more than one disk in your system while trying to install Windows can lead to problems, and the errors reported by Windows are usually very confusing too.

So here's my advice:

* Disable CSM. This way, you are always sure to be booting in UEFI mode, never in legacy. I know that Asus told you to enable CSM, but ignore them. (I spent days trying to debug a Windows problem that was related to CSM being enabled; I'm trying to save you some grief here.)

* Remove all storage except where you are going to install Windows.

* Format your destination disk as GPT. It's been a while since I installed Windows, so I don't remember if the installer allows for choosing beween GPT or MBR. I tend to used a bootable Gparted disk to format the destination drive accordingly. The disadvantage of Gparted is that you have to create the ESP manually, format it and set the correct boot bit. This is not for everyone, and I understand that. But it is important to note that if you let Windows format the ESP for you, macOS Disk Utility might not behave correctly. IIRC, Disk Utility needs a ESP of at least 350MB to behave correctly, and I think Windows formats the ESP as 200MB. That's why I use Gparted and create an ESP with 512MB (0.5GB). This way I know that both Windows and macOS will behave properly. Then I also add a destination partition for Windows, that I reformat when I run the Windows installer.

* Boot into your USB and make sure you are booting in UEFI, not legacy mode. The installation should now proceed correctly. I always reformat the destination partition using the installer, even if it was formatted in Gparted previously.


Note that Gparted is not really necessary, just some program that allows you to set the ESP to a certain size while formatting the disk as GPT.

Good luck.

Thanks man,

"AF" stands for "Exit Boot Services event".. whatever might be the exact meaning... no idea!

I formerly used the Corsair AX860i.

Don't make it that complicated, @paulotex

@PedroJSkywalker, when entering the menu with the windows installation drive selection during the windows installation, delete any partition on the destination disk! Just create a new partition which covers the entire SDD or HDD. Then select this new partition for the Windows installation. The rest is done automatically by windows. You have not to worry about GPT or anything else. Windows will automatically create its ESP during the installation. In my opinion, to create a GPT in advance is not at all a good idea and will just result in further issues.

Cheers,

KGP

How many PCI lanes does have each of these cards? Can you describe your entire PCIe population? In which slots are the GPU(s)? In which slots are the other 3 cards? Which slots are already populated by what?

Did you have a look at the user manual as recommended?

Did you see that with a 44 lane CPU, PCIEX16_4 only supports 8 lanes in case that PCIEX16_1 and PCIEX16_3 are already populated by 2x 16 lane PCIe adapters?

Also note that PCIEX16_2 only supports at most and is only compatible with 1x and 4x lane PCIe adapters!

hi，kgp，may I change the PCI slot number，when I install over the Mac os ，the Radeon Pro 580 pci slot is 6，and the audio is pci slot 6 too，how can I change it？ I am a newcomer to hackintosh，this is my first hackintosh，please tell me how can I do，thank you so much～！！
