PowerSpec BIOS Requests and Questions - AMD

The card is in the bottom slot (PCIEX16_2) next to the Thunderbolt header that it is connected to. I'm assuming it doesn't matter which USB header the card is plugged into. Could that be a problem?

I don't see a DTBT setting in the bios, what is that? Searching for DTBT didn't expose the setting.

Setting that slot to GEN3 doesn't seem to make a difference.

Discrete Thunderbolt. I can check it Monday. We can order a card and see what's going on, it'll take a few days.

I think I found the problem. There is a note in the motherboard manual:"2-18Chapter 2: Basic InstallationChapter 2
"The Thunderbolt™ card can only be used when installed to the PCIe x4 slot. Ensure to install your Thunderbolt™ card to the PCIe x4 slot."

On my system the RTX4080 Super appears to be covering that slot. I think that means I am dead in the water unless you know of an exception.

My next question is whether the ASUS USB4 card can install in the available slot PCIEX16_2 or if it has a similar restriction. I couldn't find a reference on the support site that gives specifics on the slot for this card.

Odd that it matters since the card is physically x4, the manual shows it in an x16. I'll ask ASUS about it and see if we can order one for testing.
