[Success] GA Z370 Aorus Gaming 7 + i7-8700k + RX5700XT + OC

USB 3.1 and C are separate from the USB Map on a Z370.
Take a look in About This Mac / System Report / PCI.

Z390.....Now that's another matter

Oh still not booting reliably... clearing nvram always kills my boot entry. I am getting really frustrated... usb mapping does not seem to be the issue

So many variables. Sorry I can't be of more help

Update your bios to F14, set up your usual bios settings, and use this attached OpenCore EFI.
Let me know if it works OK?
Should be fine on Big Sur as well.

Well, the EFI you generated for me didn't work -- I'd get a hard reboot as soon as the Apple logo & progress bar came on screen. However, the version you posted in response to fleisch worked just fine for me (after replacing with my own S/N, etc.), so that's good news! I'll just start with that and get other stuff dialed in, rebuild my USB map, etc.

Thanks! Hopefully I don't need to pester you again with any problems...

You had the wrong kext for the second LAN port.
Also, check your bios settings as the power cut could've corrupted it?

Please find attached, two EFI's for your system.
The first one is using custom SSDT that loads Mac OS on most systems and may be handy for having Windows in the OC menu.
The second one is using an edited version of your system DSDT.
You'll need Windows to have its own bootloader and press F12 in the bios to get to it, if you use the second one, but it will run Mac OS better.

Thank you very much Plexi! At first neither EFI you made for me worked, so I went down a hardware troubleshooting path and removed my old boot drive, an early WD Black NVMe m.2 ssd. That drive must have been damaged in the power event. I picked up a new WD Black 500 GB NVMe m.2 for $62 (!) at BestBuy this afternoon and now have a fresh installation up and running, but with a VASTLY improved EFI thanks to you.

The DSDT version you provided boots 2-3x faster than my old Clover installation and just seems faster and more stable in every way than the other versions I made.

Now I'll just have to follow the USB mapping guide and get that dialed in.

Note: I had the wrong 2nd ethernet kext because of this line in the OpenCore guide: "Atheros Killer E2500 models are actually Realtek based, for these systems please use RealtekRTL8111 instead". My Windows installation on this hardware identifies it as a Killer E2500, so that's what I went with.

I had a boot issue caused by a dead/dying m.2 NVMe SSD. Try troubleshooting your hardware setup

You have done so much already. I think i‘ll try a clean install, the may be some old clover crap still in the system

You have both LAN's working with the Atheros kext, right?
The Atheros is also identified in the DSDT so that kext is definitely the right one to use on this system.
Both the Intel and Killer LAN should be showing up in PCI.

One more thing for you to try.
Go back into Clover and press F4 at the boot menu.
Go into ACPI origin and you should see a bunch of ACPI tables.
Find the table named DSDT.aml and upload it here.
That is your vanilla system DSDT.
I can edit that and we can see if that fixes your boot issues because it will be from your actual system.

You are running on the same DSDT that I'm using if you ended up getting a result with the EFI I did for fleisch.
Should be fine.

Hi Plexi. I went through my mojave installation and found a bunch of clover crap...guess it wasn't as vanilla as I thought. After lots of cleaning everything seems to be working. I mapped the USB ports successfully. I even upgraded to big sur!! Massive Thanks!!! Could not have managed without your help!
Cheers Fleisch
