This was very helpful! I also did not know about the Processor not utilizing certain lines. Thank you very much! I was able to verify the supported bifurcation configuration, here on ASUS, and you were correct regarding the x8x8. Thank you for your time!

Hello and thank you for your time, HBA in IT mode worked like a charm, however, the NVME Expansion Card is only showing 1 drive out of 4, with one other verified good in a different system, inside both the BIOS and Unraid. I am not sure where to start with troubleshooting other than bifurcation is required, which the board is compatible with, but if you have an idea, I would love to hear it. I'm not sure what information would be useful, but please ask and I'll do my best to give specifics. I feel like the answer is simple, but I'm over here barely hanging onto an IQ over room temp. 13600k 64GB Ram ASUS TUF Gaming Pro z790 Pro WIFI Sabrent NVME Expansion Card the rest of it Will also be linking to Reddit so it might help the next unfortunate soul SOLUTION: The current Expansion Card supporting PCIE 4.0 speeds requires an x8x8x8x8 bifurcation configuration, will replace and test using the Sabrent EC-P3X4. This card will only provide PCIE 3.0 speeds, however, does not require bifurcation support.
