Why do I get the feeling there might soon be a rush for Corsair Vengeance!

@CaseySJ

Don't jump too quickly to Corsair Vengeance memory as the solution.

I had temporary access over the weekend to a second Gigabyte Designare Z390 I built.

Setup per Experiment #3. Memory in A1/B1 - 16GB, 3200MHz in each slot. CMK32GX4M2B3200C16.

AppleVTD DID NOT appear in IORegistryExplorer. Ethernet and WiFi remained active.

A strange result based on other reported results.

AppleVTD should appear regardless of the type of memory. Is it possible that the second Gigabyte Z390 Designare had boot argument dart=0 that prevented AppleVTD?

@CaseySJ

No, dart=0 was definitely removed. I duplicated the setup several times and made sure the proper EFI was being used because of the results I was seeing. This is admittedly an "outlier."

BIOS F9i, Flashed TB 33, Fenvi T-919, Big Sur 11.4, OC 0.7.0, i9-9900K

I'm thinking (just thinking) of testing what appears to be a newer model:
  • CMW32GX4M2E3200C16 (2020 model)
  • W is for Vengeance RGB Pro
  • 16GB DIMM
Yours is the:
  • CMK32GX4M2B3200C16 (2015 model)
  • K is for Vengeance LPX
  • 16GB DIMM

Something I had a problem with was I always had to reset NVRAM as the dart=0 argument would stay active after I removed it.

We can solve this by putting boot-args into NVRAM --> Delete, as shown:

In your Clover config.plist, please try deleting DMAR as shown below (i.e. remove that line), then reboot (VT-d must be enabled in BIOS). Does AppleVTD now appear in IOReg?

Holy cow! @CaseySJ , you're an evil Genius! They should bronze your brain when you're finished with it! AppleVTD showed up and the Antelope device works thru Thunderbolt! Game-changer!:clap:

The only caveat is that I can't daisy-chain my UAD Apollo and my Antelope. When I do, they disappear and Thunderbolt Bus shows up. I'm gonna go get a second TB3 -> TB2 adapter today and try to run them from both ports... AFTER I play with my AFX2DAW effects. :headbang:

Wifi -> working
Ethernet -> still out, 1G and 5G

Update: Shutdown and started back up in Windows 10 to confirm all devices were attached. Shutdown and booted to macOS X and BOOM, FULL Thunderbolt with both devices daisy-chained!

Not to be a bother but did you have a chance to try activating PTT @CaseySJ? I tried resetting CMOS and enabling PTT before touching any bios settings but it still comes back disabled. Wondering if there could be a problem with my 9900K, or if it's somehow still related to my bios screwup (seems a bit unlikely as I flashed the full chip using your bios).

Hello @SardusX,

It's highly highly highly recommended (i.e. Just Do It :)) to install F9g or F9i. I would recommend F9i. Then unlock MSR 0xE2 just by doing this: BIOS Setup --> Boot --> CFG-Lock --> Disabled. As easy as that to unlock MSR 0xE2.
When you suggest updating with the BIOS version F9i do you mean the "official" one?
I downloaded the F9i version from Softpedia:
and compared its SHA-1 /256/384/512 signature with those of the file You linked in Your "Quick Reference to Mini-Guides and Micro-Guides": they coincide so I can think they are both verified files?

Use the same SSDT-UIAC... that you are using now. Copy that file into OpenCore's OC/ACPI folder and add a reference to it in config.plist --> ACPI section using OpenCore Configurator:

Please, i have two questions:
Is the use of the OpenIntelWireless Driver (and therefore of the SSDT-UIAC-DESIGNARE-Z390-V7D.aml) compatible with the use of iMac 19.1 sysdef?
When I made the first installation of macOS mojave by following your Guide you provided me with the SSDT-UIAC-DESIGNATE-Z390-FD-DEFINE-C-TG.aml file (which I attach to this post). Do you think it can still be used with OpenCore and Catalina/Big Sur?

Thanks in advance

Just walked 2.65 miles down the hill to nearest Starbucks. Will be back soon.
