I’ve long been intrigued by Thunderbolt add-in cards. Apparently regular looking PCIe expansion cards, but shipped with a mystery interface cable to the motherboard, of which there is a small list of supported models.
It’s not a secret that these cards may work in a motherboard which isn’t supported, but full functionality is not a given. I have spent the past few evenings trawling through many forums, reading about the many different experiences people are having, and have also purchased some hardware to play around with myself, so we can dig into these problems and see what (if any) solutions there are.
Excellent deep dive into a topic I had never once in my life stopped to think about. As the author concludes, it would be cool if we ever got working, reliable Thunderbolt add-in cards for AMD or earlier Intel systems, but it seems unlikely.
