[?] Thunderbolt 3 (and UAD-2) on Gigabyte Z170X GA5

[PoppaPenguin]

In my Thunderbolt submenu I have different settings:

Security Level: No Security
Reserved Memory: 256

I also have "Skip PCI OptionRom" in my settings, which I don't see on yours, but that is Enabled. I wonder if "Ignore Thunderbolt OptionRom" on yours is the same thing? I have no idea, so not sure. I would start with turning off the Legacy security setting you have, but again, I am no expert here, just letting you know what I might try.

This is all pretty new territory for me, I just follow guides here and got my system into a place where I'm happy with it so I don't futz with it much.

I wonder, too if your BIOS is too old for that Alpine Ridge. My BIOS is F20 but I have a GAMING-5, not a UD5. There are plenty of guides around here to assist you in updating the firmware on your system. Again, I have no idea how any of this will treat your machine, take all of this with a grain of salt and keep researching.

I wish I could be more helpful, but that's all I really have to offer, try changing the settings I mentioned above and report back.

Read my above posts, I shared the settings I had which were different. Aside from changing those, I won't be more of more help. Good luck!

Make a new post and be as detailed as possible while continuing to do your own research. It's tough being out with no support but that's what you sign up for with these builds. Good luck!
