Z690 Strix-E, ThunderboltEx4, and Win11

Anyone manage to get the ThunderboltEX4 working under windows 11?

ROG Strix 690-E Motherboard, 12900K, 64G DDR5 (matched pair G.Skill)
ThunderboltEx4 plugged into the bottom PCI slot, attached with USB, TB-header, and Power.

I've walked through uninstalling/installing all of the intel drivers multiple times. Up to Date BIOS. Up to date in Windows Update. Up to date in Armoury Crate

With "Discrete Thunderbolt" [Disabled] -> Thunderbolt shows up in Control Center Loads, and I can see the attached devices with status "Not Connected". Clicking over to "Approve Devices" stalls on a blank page. About shows App version 1.0.34.0. Controller 1.41.1193.0. And PCIE tunneling is "Disabled". The Controller shows as Thunderbolt 4 (1137), 2 ports, and NVM Firmware Version 31.0

Toggling "Discrete Thunderbolt" [Enabled] breaks the driver (I still get DisplayPort Passthrough). So I get a broken driver in Device Manager. Thunderbolt Control Center is not installed. etc. If I manually install/run the Control Center app I can navigate to Approve (not in the semi-working case this page is blank), but there are no devices recognized.

I'm stuck in a trap that I can see the devices, but I can't Approve them to connect.

Hello, Pedro Sanchez.

May I ask if the problem happens when you first build? Or does it happen after a software or hardware change?
Could you help to confirm the question below for us to better understand the configuration details?
- the full model name of your motherboard and the current BIOS version
- the content of the setting in BIOS (or whether it is the default)
- the brand and model name of the CPU, DRAM, GPU, and PSU currently installed
- the OS version and OS build

Thank you.
Due to the local holidays, my responses may be slightly delayed.
For any urgent cases, we recommend reaching out to your local service center for further assistance. Thank you in advance for your patience and understanding.

My friend SuddenSaturn, we are all stuck,  supporty for this item is very very poor or NUL, i gave up, using as USB type-C instead. Every one has the same problem and no solution from Asus, but still they keep on selling it...

I was dealing with this exact same issue. I am running an ASUS ROG  Z690-E, with 128 GB Corsair RAM and an installed Thunderbolt EX4 card. After hours dealing with the same problems i logged into my Motherboard BIOS and enabled Discreet Thunderbolt setting and it fixed all this issues with me. I now have 2 thunderbolt devices connected and working. 1 being a 72 TB OWC raid and it works fine and daisy chains as well.

Thank you for sharing. I do have discrete thunderbolt enabled all the time, still not showing, although TYPE-C is working which I am using. I also came across some one who changed the slot of the card to another slot and seemed to work, is just a peety that asus as a famous brand i get the feeling they are looking in the other direction, almost everyone has an issue of same sort. Thank you I will keep on trying.. I am glad for you 🙂
