Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

[CaseySJ]

Thanks is this done through OC configurator or do I edit the plist?

Both of them do the same thing, which is to edit config.plist. You can either use OCC or directly edit the file.

Hello @viteras,

Welcome to the forum! Glad to see the working build.

Because you edited the DSDT yourself, do you have experience with ACPI and/or BIOS (firmware) programming?

Please post the SSDT that you modified.

Here it is. I have added the if "Darwin" statement as well as the 3 "External" which is the only way to have the compiler compiles successfully. Let me know if the SSDT is valid. Thanks

Alas I am not an authority on High Sierra, but we may need to use Kaby Lake platform IDs. In particular, 0x59120003 for headless. The next one to try is Coffee Lake 0x3E920003. Both of them must of course be specified in reverse byte order.

Update:

• In your config.plist, the following two items are incorrectly specified:
  • AAPL,ig-platform-id 0x3E920007 (non-headless) should have been entered as 0700923E
  • device-id 0x3E920000 should have been entered as 923E0000
• However, if you have an AMD GPU, it is best to use a headless platform ID as mentioned in the first paragraph, like this:
  • AAPL,ig-platform-id 0300923E
  • device-id 923E0000
• If these IDs don't work, then please try:
  • AAPL,ig-platform-id 03001259
  • device-id 12590000

Thanks CaseySJ, I can confirm the Kaby Lake setting worked! We now have VDA decoding on 10th gen High Sierra!

Reports from Z390 Designare users indicate that:

• Razer Core eGPU can be used withoutflashing the firmware if:
  • BIOS --> CSM Support is Enabled (but try Disabled first)
  • Thunderbolt SSDT is disabled, which in turn disables hot plug

My Razer Core X arrived this morning. I’ve enabled CSM Support and disabled the Thunderbolt SSDT - I have the icon in the menu bar, but when I switch inputs on my monitor i’m not getting any signal. Is there a part of the process I am missing?

So now with the VDA decoding fixed, I have one tiny issue left with my system...and that is the two Ethernet ports - one Aquantia AQC-107 10GBe and the other an Intel 2.5GBe LAN port. I've tried Mieze's Aquantia 10.13 patch with not much luck sadly.

Yes this one is valid. Does it succeed in hiding the GPU in slot 2?

Some questions and suggestions:

• Are you running Catalina or Big Sur?
• Have you tried CSM Support disabled?
• What is the make/model of the GPU inside the Razer Core X?
• Is it powered on and connected to Hackintosh before booting macOS?
• Have you tried pulling the video cable out and reconnecting it?
• Please post the IOReg file (IORegistryExplorer --> File --> Save As...).

With flashed firmware, we have this post by @jb007:

@jb007: Did your Razer Core X ever work without firmware flashing?

• I'm running Big Sur 11.1
• CSM support was disabled, but I changed to enabled. I'll try with it disabled and see if that makes a difference.
• The GPU is an Asus RX580 8GB Dual OC that works perfectly in macOS when it's in my system.
• It is powered on and connected before booting
• I haven't tried pulling the cable, I'll give that a try now and report back
• I will post the IOReg file once I've tried the above!

EDIT:

• Turned CSM Support back to Disabled, no change, so I don't know whether that's a good or bad thing!
• Tried pulling the HDMI cable. On plugging back in, my monitor shows a dialog box saying "New external input has been connected" and asks if I want to switch to HDMI 2, however when I do it's just a black screen.
• Please find attached my IOReg file
• Please find attached a screenshot of the Menu Bar with (what I assume to be) the eGPU icon
• I've disconnected the Core X entirely now as I've got some work to do (returned the RX580 back into the computer case), but still have that icon in the menu bar even though there is no eGPU attached...Is that right?
