Thank you! I may actually give this a try (again). I fought with trying to get my TB-III card working on my X99 Deluxe II for HOURS and HOURS and got it working, sort of, after uncounted hours of frustration. Asus offers next to nothing for instructions about how to do this and I have never found anyone who has posted having an easy time of it. There is no explanation of the BIOS settings having to do with TB configuration. Most people I have seen try to do it eventually give up. I have an 28-lane CPU and at the time I tried to get TB working, was running 2 R9-290X GPUs in crossfire. That did not work out at all. Now, I am running on just 1 GPU so I may give your method a try.
