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

@CaseySJ
Have you tried Screen Mirroring from Big Sur to Apple TV?

I’m using iMacPro1,1 with only AMD GPU (no iGPU in my CPU)
shikigva=128
I’ve the sound but not the video
It used to fully work in Catalina
Any idea what I can do?

I'll try that later today and update this post.

is there a way to check the signal strength in -db of a wifi access point, either from OS X or an I-device?

Please also post a new IORegistryExplorer file as detailed below. There's no hint of the GC-Titan Ridge in the previous IOReg file, hence a new one is needed.

• Please check that GC-Titan Ridge card is installed.
• Disconnect the THB_C Thunderbolt header cable if it is connected.
• Hold the card vertically with PCI pins facing the floor and connect the Top and Middle pins of the 5-pin J1 header with a F/F jumper wire. This will force the card to turn on.
• Disable any existing Thunderbolt SSDT.
• Boot the system and log into macOS.
• Run IORegistryExplorer --> File --> Save As... and post the saved file.

Here is my IORegistryExplorer content. No Thunderbolt SSDT applied.

That's much better. GC-Titan Ridge is on PC01.BR1A. Please try the attached SSDT in combination with SSDT-DTGP.aml.

• Copy the attached SSDT to OC/ACPI folder.
• Add a reference in config.plist --> ACPI section.
• Check that a reference to SSDT-DTGP.aml still exists.
• Disable any previous Thunderbolt SSDT.
• Reboot.
• Post a screenshot of PC01.BR1A section of IORegistryExplorer to confirm.

Hold the Option key down and click the Wireless icon in the menu bar.

Quick question regarding Thunderbolt AIC: Has anyone successfully added a Titan Ridge add-in card to this build?
I was going to pull my Fenvi card since I'm not using BT or WiFi.

@Cellubab / @qthegaijin,

Sure, will keep you posted.

I have received a Mac mini 2018 today, I was wondering to try something about daisy chaining the device. I will let you know if there are news.

Exactly! Just look at RSSI (Received Signal Strength Indicator). Then have a look at this post to decode the value:

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

I thought so too, but another one didn't fix it for me unfortunately. Please try disabling XMP Memory Profile in BIOS. We can then set memory multiplier to 29.33 for 2933MHz.

www.tonymacx86.com

RSSI	Summary	Description
-30 dBm	Excellent	Max achievable signal strength. The client can only be a few feet from the AP to achieve this. Not typical or desirable in the real world.
-67 dBm	Very Good	Minimum signal strength for applications that require very reliable, timely delivery of data packets.
-70 dBm	Okay	Minimum signal strength for reliable packet delivery.
-80 dBm	Not Good	Minimum signal strength for basic connectivity. Packet delivery may be unreliable.
-90 dBm	Unusable	Approaching or drowning in the noise floor. Any functionality is highly unlikely.

I have a GC-Titan Ridge installed in my Z490 Vision D, which also has an on-board Titan Ridge controller. In this case we assign a different Thunderbolt Bus ID to the GC-Titan Ridge. This can be done with HackinDROM as shown below. The on-board controller is most likely on Bus 0, so change TB Bus ID to 1 for the add-in-card.

This is what it looks like on my Z490 Vision D:

Thanks! I needed a little push to try this. I'll swap out the Fenvi Firewire card for the GC Titan Ridge and update this post.

Update: The card wasn't recognized in MacOS or Windows. Then I realized that the Z390 Designare doesn't seem to have a Thunderbolt header on its surface. I pulled the card and put the Firewire card back in.
