Hey all,

I own a Z370 Extreme 4, which I decided to upgrade with a (very hard to find) Thunderbolt 3 AIC (rev1). It's not showing up in device manager, nor does the Thunderbolt Software application recognize any controller.

The installation in the case was easy enough, I've followed all the steps both the mobo manual and the AIC manual explained. (Save for the mini-cd, I downloaded the drivers online instead.)

I am going to buy an Universal Audio Apollo x8 interface for this studio which connects with TB3.

The problem is that before I buy this, I wanna make sure that my new TB3 controller works. Considering the controller isn't showing up anywhere, I'm a bit scared to spend a lot of money on something that might not even connect properly.

I've tried pretty much everything I can think of.

My UEFI/BIOS version is 3.20.

Can anyone help me out?

Thanks in advance.

Dear Hale,

Thank you for choosing ASRock.

Z370 Extreme4 supports Thunderbolt 3 AIC at PCIe6 slot.
Please make sure the TBT cable connected and enable the thunderbolt support under BIOS setting.
The device manger will show the Thunderbolt controller only when a thunderbolt device connected.
You can test by connect a USB type-C device to check the Thunderbolt 3 AIC works or not.

Thank you!
Yours truly,
ASRock TSD
