Z790 Chipset & Raptor Lake

I finally found the culprit is Above 4G Decoding, when I change it from Auto to Enabled, the second sleep hang issue come back again, disable it will be ok.

Interesting. I just tried disabled and auto, but my system won't boot unless it is set to enable. You may be on to something though. What are you using for the two "resize bar" options in the config.plist? I think these are related.

ResizeGPUBars = -1?
ResizeAppleGPUBars=-1?

Then you may try to disable "Above 4G decoding" while adding boot-arg 'npci=0x2000'.

Here is my OC config file, you can compare what's the diff. I removed PlatformInfo section, I'm using MacPro7,1

I couldn't get Z790 Master Audio (ALC 1220 - Revision ID 0x0011) to work, I have tried several ways without success
here is my pictures for Config and from my system.

I was able to get it to boot with Above 4G Decoding disabled by turning on Resizable GPU Bars by first setting 4g decoding enabled, then turn on resizable GPU bars, then turn off 4G decoding. It didn't seem to help. The other weird thing is that even after the first sleep, the system starts behaving strangely. The CPU temps stay in the 60 degree range and steadily gets hotter, with spikes in the 90 range while not even doing anything. It seems something weird is happening with the CPU power management after the first sleep.

I can disable Abobe 4G in any case, my macos always boot, found a thread maybe you want to read:

[HOW TO] OpenCore 0.7.4 > 0.7.5 differences

Monthly message by vit9696, please read it carefully, there is no better place to see what's new in OpenCore. https://dortania.github.io/hackintosh/updates/2021/11/01/acidanthera-november.html Main changes applied in 0.7.5 version: Improved Linux boot and revised OpenLinuxBoot documentation...

My setup almost perfect now, regrettably this won't work for you, maybe it's close to solve.

I tried to duplicate your config file in my setup, but the same issue with crashing on second sleep still exists.

In case anyone is wondering whether to use MacPro7,1 or iMacPro1,1 with the 13900K, I created a second config.plist that use MacPro7,1. Benchmarks are almost identical to iMacPro1,1. Single core was exactly the same, 2233, and Multicore was almost identical, 26076 for MacPro and 26120 for iMacPro . I would say iMacPro1,1 is better as I do not need to add the CPUFriend related kexts.

Nearly finished with my z790 Mac Studio 'alternative'.. Went all out on this guy. I was actively saving up for a real Mac Studio but my needed configuration would run about $6K, eventually I just said eff it and plunked everything down on this beast:

Gigabyte Aorus Master
Intel 13900K
Powercolor RedDevil 6950XT
Crucial Vengeance 128GB DDR5

I do a ton of content creator crap as well as a lot of VM stuff. In hindsight I'm probably making the right decision sticking with Intel as I will likely need to dual boot to a valid Windows at some point (not just a Parallels VM) for testing. I don't know the state of Parallels on Apple Silicon.

I'm going to attempt to make a build log page in a day or so if it helps someone else with a similar z790 system.

Minor issues:

1 - I'm sure this is easy but as the CPU is being spoofed as Comet Lake I have no idea how to manually fill in the blank.

2 - I don't care about wifi, but I haven't figured out the Marvell Aquantia AQC113 10gig ethernet yet. Not a huge issue, I'm using a Best Buy USB-C to Ethernet dongle for the time being but it would be nice to have.
