WiGig card works in PCIEX1_1, PCIEX1_2, PCIEX4_3 slots, and does not work in PCIEX16/X8_1, PCIEX8/X4_2 on my motherboard. I think it can be reproduced on any AM4 motherboard with SLI support that has an additional PCI-E X8 slot from the CPU. My pc specs: CPU: AMD Ryzen 7 2700X Motherboard: ASUS ROG CROSSHAIR VII HERO

In my experiment, WiGig card was in a chipset slot. I have tried to tweak BCLK to make WiGig appear in the CPU slot without any success.

Recently I played a bit with BCLK on my motherboard. If BCLK is outside the 97-109 MHz range WiGig card just disappears from my system (become undetected by OS). When BCLK within that range, it works fine. There is something wrong with PCI-E interfacing of that card.

I have similar issue. My PCI-E card won't detect in PCI-E Gen 3.0 slot connected to my Ryzen 2700X CPU, but works fine in PCI-E Gen 2.0 slot connected to X470 chipset. Intel wireless card is not visible in device manager on Windows, and not listed by lspci on Linux when in CPU PCI-E Gen 3.0 slot. Any other device like GPU, Sound Card, USB Host controller, etc. works fine in that slot. looks like in your motherboard X399M Taichi all PCI-E x16 slots are connected to CPU.

I can confirm, played a lot with wireless, not a single BSOD. I was unable to play without BSOD before fix more than 1,5-2 hours. My PC specs: Ryzen 2700X, Asus ROG Crosshair Hero VII. Still my system can't detect card if I put it in the second PCI-E x16 Gen 3.0 slot, works well on the top most PCI-E x1 Gen 2.0 slot.

I mean firmware update for Vive Wireless, Vive deployed test hotfix on april 25, now my wireless running ok, motherboard Asus ROG Crosshair Hero VII.

Looks like they fixed it with latest firmware update, works stable for about six days.

I'm running vive wireless on Asus Crosshair VII hero board, cpu is ryzen 2700x. Still getting watchdog BSODs, tried almost every advice from web, without any success. The following is only guess, from my experience: -problem is hadware related, there is no quick and easy fix; -it's related to pci-e standard, and how it implemented on WiGig card; -WiGig card won't detect on any pci-e gen 3.0 slot connected to lines directly from Ryzen cpu; -WiGig card stablility depends on pci-e slot; -WiGig card stability depends on BCLK, mine works best on 97Mhz; -WiGig card only works on pci-e gen 2.0 slot from SouthBridge on AMD Ryzen boards; -there is no 100% working motherboard; -increasing SouthBridge voltage may increase WiGig card stability, do it on your own risk.
