Common Problem #2: When peripherals are connected at boot time, theyвЂ™re not detectedД«ut if I subsequently unplug it, and plug it back in, then it works? These cards will need some more initialisation that IвЂ™ll be looking at in future. I have noticed that some (Alpine Ridge for example) cards come up with a PCI Vendor/Device ID of 0xFFFF/0xFFFF which would mean that they wouldnвЂ™t be enumerated by the system. This is likely to differ for other cards. Jumpering the GC-TITAN RIDGE into action. In some cases a separate +3.3V supply will need to be applied (via a 10K resistor for example) to the вЂњforce powerвЂќ pin, which on the GC-TITAN RIDGE is pin 1. It will not necessarily work for every AIC. This modification works thanks to a weak pull-up on the input at pin 3 meaning there is +3.3V present. Pin 1 is clearly marked on the connector as being at the top of the card, and in the drawing of the connector. Note that you are actually shorting pins 1 and 3. On the Gigabyte GC-TITAN RIDGE (one of the most popular cards for Thunderbolt hacking) it is regularly reported that you can вЂњshort pins 3 and 5вЂќ. One of the pins on the mystery Thunderbolt header interface on the rear of the card is an вЂњenableвЂќ (technically вЂforce powerвЂ™) signal. Common Problem #1: It doesnвЂ™t work at allД¬ard not detected, nor any attached devices, nada. 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.

ItвЂ™s not a secret that these cards may work in a motherboard which isnвЂ™t supported, but full functionality is not a given. 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. IвЂ™ve long been intrigued by Thunderbolt add-in cards.

The situation is no better for Thunderbolt 4 however many technical details differ from what is written on this page.

Presently everything here concerns Thunderbolt 3 add-in cards. It does not assist with basic Thunderbolt troubleshooting. This article is written for people from a technical background who are seeking to retrofit Thunderbolt to older / low end PCs.
