I was very excited about an AMD system that officially supports TB3 and chose the ASRock X570 Taichi partly because of that.
Since ASRock does not offer a Titan Ridge Thunderbolt controller AIC, I got the Gigabyte GC-Titan Ridge dual port AIC.
- The X570 Taichi is running UEFI version 1.70A
- Gigabyte AIC installed in PCIe slot 5, USB 2.0 and TB Header cables are plugged in
- Thunderbolt is enabled in motherboard’s UEFI
- Using the latest versions of Win 10 1903 and the Thunderbolt drivers (1.41.648.4)
- 3700X, no overclocking
- 2 x 16 GiB Crucial ECC DDR4-2666
- GPU: Radeon Pro WX8200 in PCIe 1
- 0.5 m mDP-mDP (officially rated for DP 1.2) cables from GPU to TB AIC
- The TB3 AIC is very firmly installed, doesn’t jiggle at all when plugging a device into or unplugging it from its Type C ports
- The BSOD also appears when plugging an USB thumb drive into a connected USB 3 hub so there is absolutely no mechanical stress on the TB3 AIC.
- Ethernet: Intel XL710 QDA2 in PCIe 3
- All devices including X570 chipset with latest publicly released drivers available at this time
The two Thunderbolt 3 Type C ports seem to work fine (tested various adapters: USB 3.1-SATA adapter, USB Type-C to 4 x Type A 10 Gbps USB hub, USB-C to HDMI/DisplayPort out) if the devices are already connected when the system is still powered off.
Update: When plugging in a non-Thunderbolt USB 3.x Type C device or unplugging one from the TB3 Type-C ports I get a BSoD (WHEA_UNCORRECTABLE_ERROR).
With a simple USB Type-C male to Type A female adapter in one og the TB ports I can connect and disconnect USB 2.0 devices without issue so the passthrough connection to the motherboard USB 2.0 header seems also fine.
Thunderbolt works seemingly fine, however it only negotiates a 20 GbE networking link between the GC-Titan Ridge AIC and a Mac mini 2018 (also with Titan Ridge TB3 controller) with a 2.0 m Belkin TB 3 cable that is rated for 40 Gb Thunderbolt/100 W Power Delivery (but without DisplayPort capability for some reason)
So it seems the Intel USB 3.1 controller and DisplayPort muxing (?) has issues ?!
Stuff I tried without any effect :
Tested a second unit of the GC-Titan Ridge AIC
Changed the internal motherboard header and power cables to the GC-Titan Ridge AIC
Changed mDP ports on the GPU that are connected to the GC-Titan Ridge AIC
Newly installed Win 10 Pro 1903 on an erased SSD (and BIOS/MBR setup instead of UEFI)
New AMD chipset drivers that came out July 31st
Tried the more current AMD Radeon Consumer driver package instead of the enterprise one for the WX 8200
Tried a different GPU (NVIDIA Quadro P2000, also with DP 1.4), same result
Tried a different PCIe slot for the GC-Titan Ridge AIC
Any idea what’s causing this? I know that this is an unsupported configuration but I hope it can be fixed.
Any help is greatly appreciated!
