ASUS X570 I-STRIX -> Rear M.2-> ADT Link M.2 to PCIE16 Adapter-> Gigabyte Titan Ridge rev 2.0 Thunderbolt 3 AIC-> (Thunderbolt 3 cable)->Akitio Node + RTX 2080TI , Windows 10 EGPU detected in device manager, but NOT by NVIDIA control panel ,Unable to...
I am trying to get thunderbolt 3 to work on my AMD desktop system which I built recently, the system has a Ryzen 9 5950x with a RTX 3090 FE DGPU on the ASUS I-STRIX X570 motherboard. Chain of devices is as mentioned in the topic title.Some of the hoops I had to jump through to make this system work are as follows
1) Shorting pins 2 and 3 on the 5 pin THB_C header of the Gigabyte Titan Ridge Rev 2.0 AIC
2) Added Hack flags 0x600 in windows registry to enumerate the PCIE bus after boot up
So far what I see working is the following
1) Thunderbolt controller gets detected by windows and I am able to complete driver installation from gigabyte's website.
2) I got Windows 10 to detect the Akitio Node EGPU case on hot plugging to the Titan Ridge AIC (I had to allow connection to this device using the thunderbolt app , but this is standard )
3) Thunderbolt networking works when setup in peer to peer mode between my razer blade 15 laptop and the desktop (Detecting a 20Gbps Ethernet link and I am able to transfer data both ways at 1GBps)
That is sadly where all the good news stops
I am facing the following issues
1) USB 3.0/3.1 functionality does not work , hot plugging my external usb 3.0 type C pendrive does not work/drive is not detected
2) Even though the EGPU(RTX 2080Ti ) is detected, I am unable to drive/detect another display using the EGPU
3) Cannot detect two GPU's inside NVIDIA control panel
4) Can't see two GPU's inside MSI afterburner but I see them in GPU-Z
5) After wake up from sleep, the PC crashes abruptly every time and this happens only when the EGPU is connected over Thunderbolt 3
I am tearing my hair out trying to fix this , any help is welcome
