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

[qmediaservices]

@CaseyJS, I don't know if this make sense, I did a bit of research and I find this:

Run a good benchmark like Unigen Heaven, when the GPU gets over ~55-60C the fans will turn on. The fan is controlled by the vBios and will function the same way regardless of the OS. My GTX 970 is the same way.

I download the software and the fans run like crazy, I bench the extreme preset and It works, but a soon I stop this test the fans stop after a few seconds and the flickering start again. Any ideas?
Thanks again for all your help.

Hi Casey.

I have this on Memory Tab. The 4th slot is missing. (It's empty).
If I remember prior to 10.14.4 the slot was visible.
What do you think?
Thank you
Max

Some comments:

• It is a good sign that the fans are starting and stopping in relation to the load applied to the GPU.
• But the screen should never flicker.
• If you have a good HDMI cable (HDMI 2.0 compliant if using 4K at 60Hz), if the connections are okay, and if the power supply is good (750W), then I would do this:
  • Test the RX 580 in Windows. Do you have Windows installed on this machine?
  • If the screen flickers, then you may have a defective card.
  • If your RX 580 is still under warranty, you can contact the manufacturer's Tech Support department or use their website to open a ticket.
  • If you are within your return/exchange window, you could switch to a different make/model.
    • Sapphire Pulse RX 580 (not Nitro) is recommended.
    • MSI Gaming X (similar to mine) works well.
    • MSI Armor is also good.
    • Probably several other good choices out there.

First things that come to mind:

• Power down the system and remove power cable. (Yes, remove power cable.)
• Check that all 4 DIMMs are seated properly in their DIMM slots.
• Power the system back on and enter BIOS Setup.
• Check that BIOS F6 is running. Under certain circumstances the motherboard will automatically switch back to BIOS F3.
• If F6 is running, go to "M.I.T." section and enable X.M.P. Memory Profile 1.
• If F6 is not running, flash to F6 and set BIOS parameters.
• Check that all 4 DIMMs are detected by the BIOS. One of the BIOS pages will show this.

removed power cable...
same situation
I have only 3 DIMMs installed.
Last check is to reseat the Dimms.

Some comments:

• You will need the complete High Sierra installer (between 5 and 6 GB).
• If you encounter the error again during Step 11 (or any other), please open the Installer Log from the Tools menu (CMD-L?) and grab a screenshot of the error.

This option should be available from the M.I.T. section of BIOS (Classic Mode, not "Easy Mode"). Also ensure that your RAM supports XMP 2.0.

@CaseySJ
Thank you for your comments.
I will try to get the log.

My RAM does not support XMP 2.0. Is XMP supports RAM required to install macOS to this motherboard?
In that case, I need to buy another RAM.

Hey Casey,

I noticed you updated your guide and included a handy platform chart. I was going to go with the 10.14.4 mac mini (non-headless) for now. Where do I set the platform for my system? Do I have to use 0x3E9B0007 like that exactly? Noticed in Devices --> Properties tab it doesn't look like that.

I tried these;

Fake Id= 0x59128086
ig-platform-id = 0x59120003
Inject intel

I am getting kernel panic when I try to make a boot with IGPU.

And I also tried these;

Fake id= 0x3E9B8086
ig-platform-id = 0x3E9B0007
Inject intel

This time after finishing verbose screen goes to sleep

You also mention about this 0x3E980003 in headless mode. How can I use this in headless mode? I don't know anything about headless mode.

XMP-compliant DIMMs are not required, but in this case BIOS might hide XMP options. For best long-term compatibility, it is better to use XMP-compliant DIMMs -- but this is your choice.

If you connect bluetooth keyboard or mouse to BCM943602CS, are you able to wake the computer via it?

Yes this should be possible. I'll make a note to test it this evening.

Confirmed. Wake-from-sleep via Bluetooth keyboard works perfectly.
