[SOLVED] ASRock X570 Taichi/Gigabyte GC-Titan Ridge AIC: Thunderbolt 3 devices OK - But USB 3/DisplayPort device Hotplug causes BSoD :(

In this thread post by Wendell, it shows how to remove the DCH drivers, and (yes, kind of weird) go to Intel’s page and get the legacy drivers.

Thunderbolt-(Compatible) and Threadripper 3000 - Setting it up

Thunderbolt (Compatible) on my AMD Ryzen or Threadripper sysem!? Yes, it’s true. You might have read the many, many posts on the internet of folks struggling with this setup. It’s more of an “own goal” from Intel than an AMD problem and I’ll explain why. (Be sure to check out our past videos on TB on AMDs platforms, and our recent Designare TRX40 review). We must be careful not to infer or imply this is true sanctioned- or certified-by-intel Thunderbolt; it isn’t. It’s “Thunderbolt Compatible” PCIe over USBc. This distinction is incredibly important – hardware manufacturers have been keen to adopt the OPEN standard that underlies Intel’s implementation of Thunderbolt, HOWEVER certifications of this OPEN standard have been slow coming… at least from my consumer perspective. This is why we take matters into our own hands and fix it ourselves. We were the first group to cover hacking Intel’s Thunderbolt onto AMD’s platform all the way back on first-gen Threadripper. With modern TB controllers, very little has to be done. There is one key thing to understand, however: DO NOT INSTALL THE THUNDERBOLT DCH DRIVERS DCH is the new “driver model” Microsoft is moving to. It is more modern. There are DCH drivers available for Intel Thunderbolt controllers, but you don’t want them. They appear to have had quality control on only 2-3 models of laptop and literally no other devices. Do not install the Thunderbolt Control Center from the Microsoft Store. [image] How to recover if you accidentally installed the DCH driver I haven’t had perfect luck here. From an administrative command prompt, sc delete nhi then do [image] and finally reboot (which is critical) will almost always let me install the non-DCH drivers for thunderbolt. P.s. These dch drivers are SUPER messed up, even on pure Intel platforms, for the half dozen or so Dell and HP lapops of the last 18 months I was able to get my hands on. So “Legacy” right now is my recommendation on any platform… Setting Up the …
