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

What is the model name/number of your LaCie Rugged? All LaCie Mobile drives are USB 3, but LaCie Rugged models come in several varieties.

Does the LaCie Mobile mount...
  • ...when connected via USB-C to USB-A cable?
  • ...when connected via USB-C to USB-C cable to front panel USB-C port (if you have one)?
  • ...when connected to either of the two Thunderbolt ports?
Suggestions:
  • Check BIOS settings (see Post #1)
  • Run IORegistryExplorer, then:
    • Scroll down to RP05 and post a screenshot
    • Scroll down to XHC and post a screenshot

These two models are what I tested

Does the LaCie Mobile mount...
  • ...when connected via USB-C to USB-A cable?
    • Yes
  • ...when connected via USB-C to USB-C cable to front panel USB-C port (if you have one)?
    • Only the back IO port. I do not have a front panel
  • ...when connected to either of the two Thunderbolt ports?
    • No
I will check BIOS settings again.
EDIT: Also here are the screenshots attached
EDIT2: BIOS settings are set based on the guide below
(Thanks to @Zip1 for helping put this together!)
  • Press F2 to toggle to Advanced Mode.
  • Press F7 to Load Optimized Defaults.
Now make the following settings:
  • Tweaker
    • Advanced CPU Settings → VT-d → Disabled
    • Extreme Memory Profile (X.M.P.) → Profile 1
  • Settings
    • Internal Graphics → Enabled
    • Above 4G Decoding → Enabled
    • Thunderbolt(TM) Configuration
      • Security Level → No Security
        This will trigger a 'Save & Exit' dialog so press ESC to close the dialog.
      • Discrete Thunderbolt(TM) Configuration
        • Thunderbolt USB Support → Enabled
        • GPIO3 Force Pwr → Enabled
    • USB Configuration
      • XHCI Handoff → Enabled
  • Boot
    • Windows 8/10 Features → Other OS
    • CSM Support → Disabled
      Some devices such as GPUs may require CSM Support to be enabled. There is no harm in setting this to either Enabled or Disabled. Use the setting that works best.
  • Save & Exit → Save Profiles → Save to Profile 1
    This preserves the firmware settings for easy recovery.

It detects my RX580 without problems.

That's great! When you get some free time, would you mind running a "render" of the .ISO/DVD to h.264 conversion feature that Video Proc advertises and post an in-process screen shot of Activity monitor. Like this:

EDIT2: BIOS settings are set based on the guide below
Both of your LaCie drives are USB-C 3.x models. If you boot the system with those drives already connected, do they show up in macOS?

Also, are you certain that the USB-C cable supports USB 3.x protocol? Most USB-C to USB-C cables on the market only support USB 2.x, which we have disabled on the Thunderbolt/USB-C ports to avoid exceeding macOS's 15-port limit.

One way to check this is by connecting the LaCie to a real Mac using the same USB-C cable and running IORegistryExplorer on the Mac. Then scroll down to XHC (please do not use IORegistry's "search" field because it hides details) and check if the LaCie is attached to any HSxx ports or if it's attached to the Mac's Thunderbolt ports at either RP05 or RP21 or RP09 (depends on the Mac).

Hi there, Firstly, thank you so much for this incredible guide. It was a painless setup. I'm interested to overclock my system, and having never done it before, was excited to check out this guide. However, my BIOS is newer than the one used here and uses different terms, which is frustrating as the guide looks perfect. Do you know of any resources to 'translate' the old bios terms so I could follow this? Many thanks
 
Please link for Z390 designare bios F9G. On link for guide the only new version f9h, but he is black screen for me. F9b is normal working.
 
Does this method disable the bt+wifi card for windows disk also? I have clover managing double boot
The Fenvi FV-T919 or other Broadcom card is not disabled in Windows, but if possible, do not install drivers for this card in Windows. Let Windows use the Intel CNVi module.

How do I do that? Currently no connection within windows but all good on high sierra side (lan though)

Please clarify the problem you're trying to solve:
  • Are you trying to enable the Fenvi FV-T919 in Windows?
  • Are you trying to enable the Intel CNVi WiFi/BT in Windows?
  • Are you trying to enable any WiFi/BT in Windows?
