So ..... 8 hours later ..... no luck with my NEW Titan Ridge card with my Caldigit TS3 Plus dock.
Firmware is updated before anybody asks. Also, tried another Thunderbolt 3 cable, no difference.
I'm getting this odd feeling that my Sage10G/WS motherboard is defective.
New Titan Ridge card, USB header connected, PCIE power connectors connected, Thunderbolt header connected (I disconnected everything and re-connected).
Re-installed Windows, checked the permissions over 1000x times today, went in the BIOS, checked those 1000x. Even tried different permissions in Windows and the BIOS and got no luck.... even tried re-applying settings for permissions as was suggested by someone else in the thread (too tired to quote, but if you're reading this, you know who you are- thank you for the advice on that).
So right now, it's set to 0-No Security in the BIOS, but my displays are the only thing that work when I boot into Windows or Mac.... and it's not consistent.
(for the following, I have both mini displayport to displaypoirt adapters connected to my Vega 64)... and an HDMI laying there in case it doesn't pick up, then I plug in the HDMI, switch my input on my monitor to HDMI 1 & sure enough it's working....
So here's the synopsis:
Under Windows:
Sometimes it will default to my HDMI out .... WHEN NOTHING IS PLUGGED IN (which is annoying) .. then ... it's only display out that's working, none of the other ports on my Caldigit dock work. Sometimes, when I have to plug in HDMI, then I have to unplug/replug my Thunderbolt 3 cable to get my displays back.
Sometimes, I boot into Windows and 'some' of the functions on the Caldigit will work- and I'll get an error about some of my USB ports may not be working in Windows.
Sometimes, I boot it up and everything works, I mean all the ports everything. (this becomes obvious because immediately, I have internet access... I have my hard wired connection to my dock and no other network connections going to the computer, no wifi drivers- done on purpose to make diagnosing easer).
Sometimes it doesn't work at all and I have to scan for hardware changes in device manager. Sometimes that doesn't work and I have to unplug/replug Thunderbolt 3, THEN do scan for hardware changes.
Under Mac:
Only displays ... and sometimes that doesn't work right away, I have to plug in HDMI, then unplug/replug my Thunderbolt 3 cable.
No other ports work under any circumstance ... with SSDT-DTPG.aml & SSDT-X299-TB3HP.aml in my EFI -> CLOVER -> ACPI -> patched folder.
Weirdly ... under Windows, enabling USB & Thunderbolt boot support in the BIOS made everything show up way more consistently .... but then my computer for some reason won't even load Clover when I have those options enabled (once I replugged my SATA drive with Mojave on it).... so that option is out.
I'm completely lost as to what's going on and I'm exhausted and am heading to bed. Wiped my temp Windows install and I may attempt this again over the weekend. Either it's a hardware issue, or it's one minor STUPID user error on my end.... but this has gotten ridiculous now.
Edit: Oh and I forgot to add.... on my Macbook Pro.... it works absolutely perfectly, everytime, no matter which cable, if I plug it in before I turn on, after it's been on etc... no issues with the dock, no disconnects, proper speeds, everything. So I know for sure the dock is fine.
