Positive: I double check it's Alpine Ridge Rev 2.0.
If I point the card (metal pins) down to the ground, I count from the top of the card. I short pin 3 and 5.
I confirm the card shows up in 'Thunderbolt' section and one findings I have is that if I don't have SSDT, the speed is 20x2, if I have SSDT, speed is 40x1. I confirm black magic mini recorder (a TB2 device) works, hotplug works.
I've read that Thunderbolt display has issues with Alpine ridge. Also USB doesn't work, I can charge my iphone but no data.

@oreoapple, To double-check, you're using a GC-Alpine Ridge (not Titan Ridge)?
Correct. But when we flash the firmware, the controller operates in non-ICM mode and unhides itself. Moreover, even if the firmware is not flashed, we can use an SSDT to unhide the controller and enable Thunderbolt Bus. We have a repository of such SSDTs located here.
Yes, I suspect something like this may be happening on the Gigabyte Z170X UD5. If the GC-Alpine Ridge works for @oreoapple on a more recent system (newer UEFI - Z390) then it lends credibility to this argument against the older Z170 UD5.
