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

[CaseySJ]

@CaseySJ Amazing! It's working partially now! Feel free to put this patch to HackinDROM.

With the mod ROM, the Thunderbolt device cannot even be detected in IOReg w/wo the SSDT-TB3.aml. But with the SSDT-TB3.aml alone, my ASUS laptop is able to detect the USB ports on my PowerColor Gaming Station (thunderbolt 3 pcie) either coldboot/hotplug and before/after sleep/wake. However, neither of my 6900 XT or RTX 3090 are detected w/wo the mod ROM and/or SSDT-TB3.aml either through coldboot/hotplug/sleep/wake in IOReg and System Report. Also, the Thunderbolt bus seems not detected in System Report (shows Thunderbolt: No drivers are loaded) either w/wo the mod ROM and SSDT. Is it possible to repatch the ROM to get the bus detected? I'm still in Catalina 10.15.7 BTW.

I attached my IOReg and System Report results below.

Hello @shiecldk,

Because your firmware is NVM 62, it may be difficult to modify. I would recommend the following experiment instead:

• Flash the modified Designare Z390 NVM 33 and see whether Thunderbolt Bus gets activated.
• You can always flash the original NVM 62 if things don't work.
• Use the Thunderbolt SSDT that was sent in my last reply. It's okay to use that SSDT with NVM 33.

Finally bought a Corsair RM850x 80 PLUS Gold 850 Watts, will check if my be quiet! Straight Power 11 is creating the short circuit
Supernova not available in Europe
if anyone has the same Corsair please let me know if it is working properly for you

Please note that PSU cables are not always interchangeable between different brands. In general we should only use the power cables that come with the PSU.

Thanks. I tested the ROM. However, it shows the same results as before (no Thunderbolt device detected in IOReg) w/wo the SSDT. Do you have the original Titan Ridge ROMs that I could used to compare the patches?

Also can be different with SAME brand but different model numbers, and this is certainly true with Corsair power supplies.

Please refer to this guide:

OUUUH!
my be quiet! Straight Power 11 causes short circuit! Now I hope they will take it back
No more issue with Corsair to boot, even Fenvi's bandwidth is a little better. Will check how Intel WiFi is now, because with be quiet! it was awful too

We have come across a couple of motherboards in which we were never able to activate Thunderbolt Bus despite iterating through several modifications of the firmware. So keep that in mind! Meanwhile, here are links to (a) original and (b) modified NVM33 from Designare Z390 (top of Post 1). This pair can be used for identifying the changes.

A general observation: I am regularly losing Thunderbolt awareness and connectivity to the Apollo 8 with this Z390 build and OpenCore 072. When it does connect, I no longer have hotswap. I am using the same EFI "Thunderbolt fixins" that I've been using for about a year now. BIOS = Z390DESI_modMC_01052021_0906_Rev_0xEA.F9i
---Rolling back to OC 071 and F9i.

Hello @jiffyslot,
What about your BIOS -> Thunderbolt configuration ?

I didn't change anything from what was working perfectly. I had full Thunderbolt connectivity, user-authorized security, hotswap, and AVB with Apple Thunderbolt-to-ethernet dongles. Not any more. I rolled back to F9i, OC071, and disabled VTD in the BIOS, and now it works again, sans VTD features.

So, I've read all the info on USB troubleshooting. It looks like using a PCIe USB card and connecting everything to that (using powered hubs when needed) is the best solution? USB3 and USB2 can be mixed on this card?
Or is it still better to connect all USB2 devices to a powered USB2 hub connected to an internal USB2 port of the Z390, and use the other ports for USB3 stuff?

Hm. Just lost my Korg Wavestate(USB2) again. Connected straight to my new Fresco chip equipped PCIe USB board. So, still USB trouble.
Any ideas/tips welcome. May also be a Korg bug, of course. But I haven't seen other WS users complaining.
