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

[Inqnuam]

@Inqnuam,

Are you also using any Samsung NVMe or SATA SSDs? If so, which ones?

I have a NVMe 970 Evo Plus 500GB, which is my main drive where Big Sur 11.5.0 is running
and a SSD 860 EVO 1TB, there I have other macOS versions for testing

@Inqnuam,

Am I seeing it correctly that the users who are losing network with VT-D disabled all have 9900k?

So to jump in on the tests for Antelope on TB3, on my Z170X-Designare w Flashed Titan Ridge v2 on OC 0.6.8/Big Sur 11.2.3 I can get into Big Sur with:

BIOS:
VT-D - Enabled

Config.plist:
- DisableIOMapper: disabled
- dart=0: disabled

BUT

I lose all USB ports when DisableIOMapper is disabled so I cannot actually get into the OS aside from login screen .

UPDATE:
Updated OC to 0.7.0 and Big Sur to 11.4 and same results with my system, no USB.

Elias --> no problem (flashed Titan Ridge firmware)

• Inqnuam --> no problem (flashed Titan Ridge firmware)
• Me --> no problem (flashed Titan Ridge firmware)
• We are all running Big Sur 11.4 or 11.5

@CaseySJ

Another data point for your TB Apple Ethernet adapter work.

I plugged a Cable Matters TB3 to TB adapter into the lower TB3 port and plugged an old TB Apple Ethernet converter into it.

I enabled VT-d in BIOS, unchecked DisableIOMapper and removed dart=0, I was one of those who lost board Ethernet and WiFi, but the TB Apple Ethernet was active.

If I uncheck DisableIOMapper, but use dart=0, board Ethernet and WiFi are active, but TB Apple Ethernet is inactive (no driver per System Info -> PCI.

If I check DisableIOMapper, but remove dart=0, board Ethernet and WiFi are active, but TB Apple Ethernet is inactive (no driver per System Info -> PCI.

I haven't found the combo that keeps board Ethernet, WiFi and TB Apple Ethernet active.

iMac19,1, i9-9900K, RX-580, Fenvi T919, Big Sur 11.4, OC 0.7.0, BIOS F9i (not patched), flashed TR firmware 33.

While booting, the Gigabyte BIOS splash screen displays the message: "Broadcom NetXtreme Gigabit Ethernet (BCM57762) is detected (PCI-E)" It detects the Apple Ethernet chip. Why display this message?

The sample size is too small to draw a conclusion. @Inqnuam has the i9-9900KF (no iGPU), but everything still works when AppleVTD is present.

Once a few more users update their BIOS let’s see if a pattern emerges.

Do Ethernet and WiFi still work? As for USB, are you using USBInjectAll or USBPorts? Are the number of ports limited to 15 and “XhciPortLimit” is unchecked?

 

[SCaRL3T]

Hello @SCaRL3T,

Some questions and suggestions:

• Which version of BIOS is installed?

BIOS F9i

• Which slot is the Fenvi plugged into?

PCIex1

• Have you tried moving Fenvi to another slot?

no the other is block by the GPU (SAPPHIRE Nitro+ Radeon RX 5700 XT 8G)

• Have you tried CMOS Reset?

yes

• What other PCIe cards are installed?

none

• How many NVMe SSDs are installed?

2

• What are the makes/models of all NVMe SSDs?

Samsung 970 EVO Plus NVMe M.2 (1 To) --> macOs
SanDisk Extreme PRO M.2 NVMe 3D (1To) --> data

Yes. I have tried almost every combination so far that I can think of. Each time results in these errors being thrown during boot. Only occurs when DisableIOMapper is unchecked:

I cannot tell if networking works since it wont let me log in.

Do you happen to have a PCIe add-in-card with USB ports?

Not on this build, only add in card is the Titan Ridge V2 and it is not plugged into the USB header currently.
