[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

can you recommend a webcam that works
out of the box?
 
This is the exact GPU I have:

Sapphire Radeon RX 5700 Xt 8GB GDDR6 HDMI/ Triple DP (UEFI) PCI-E Graphics Card https://www.amazon.com/dp/B07T8C3SM8/?tag=tonymacx86com-20

I do not I just returned my Gigabyte 5700XT reference card and my XFX RX560. I suppose I could go grab one again. lol Best Buy hates me by now. lol
I'd like not to return my Sapphire Nitro+ as it looks amazing. :( But since my primary use of this machine is macOS, probably I'll be forced to.

You may also try using the iGPU. This means:
  • No need to visit Best Buy!
  • Removing RX 5700 XT from the system.
  • Setting Platform ID to 0x3E9B0007.
  • If you have a USB-C to DisplayPort cable, you may plug that into either of the two Thunderbolt/USB-C ports on the rear IO panel.

Hopefully we can find a fix or figure out if its something working with the GPU thats causing it that can be fixed so you wont have to. Just strange its happening with a reference card as well as the Nitro+ Sapphire. But didn’t happen after I put the proper DSDT files in patch with my Gigabyte 5700XT Reference card.
 
Hi.
Thank you very much everyone for the research to get the RAM up to 128 Gb.
I have managed to install two 32GB memories, and it works correctly.
I have tried to install two 32GB and two 16GB and they work but I have lost the hardware acceleration of HEVC.
Do you have any suggestions.
I also don't get the memory section about this mac.
And the performance declined.
Thank you so much and Happy New Year.

This message is for @samtimbaud: I think you need to update your BIOS to F8! Can you boot into Windows? Or use another computer to download the bios update and load in onto your system?
 
EFIClone-v4 has been replaced with EFIClone-v5 in the post below. We're looking for volunteers to try this out as described in the original post.
