It feels pretty random honestly. In this case it happened right when I finished watching a youtube video but trying to reproduce it didn't work. Other freezes didn't seem to happen during any particular action.
Just had another freeze while trying to write an email in Safari.

This time it froze completely. No cursor, no nothing.

Edit: Right after that freeze, restarted, connected a USB3 SSD, froze completely. Restarted again, connected this USB3 SSD again, no freeze. This is pretty weird and happens often now.

There's another Process of Elimination suggestion for that:
  • We perform a fresh installation of Mojave or Catalina on a spare SSD.
  • We do not install any of our third-party apps (simple utilities are okay).
  • We then disconnect the internal SSD/NVMe.
  • We boot from the fresh installation and check whether the system is stable during YouTube, browsing, etc. If the system is rock solid, then we install one "heavy" third-party app at a time (on the fresh install disk) and check again for reliability. Then we repeat with other apps.

Thanks for the suggestion, Casey!

Seems like a pretty laborious process which I'll probably end up doing soon if the system keeps crashing like this.
I'm just curious what you mean by the "heavy" third-party apps.

These would be (a) pro apps like Final Cut, Adobe Premiere, Photoshop, Logic Pro, Da Vinci Resolve, etc. and (b) apps that install drivers such as UAD audio devices, Antelope audio, etc.

Technically, we might not need a Thunderbolt header. Instead, we could bridge two wires on the THB_C port of the add-in-card itself to force it to power on the Thunderbolt controller. However, I'm not sure if it's possible to add a second Titan Ridge controller. I plan to test this soon.

You can add a second Titan Ridge without problems. With de correct "ThunderboltConfig" you can obtain full tree Node & HotPlug. (I configured it in PEG & PXSX) Tested with eGPU & Sonnet 10Gbe.

Can you please share your ThunderboltConfig and SSDT? If you're getting a Titan Ridge to work normally, all of us would be extremely interested to see how you did it.

EDIT:
  • Maybe I misunderstood. Are you using a flashed GC-Titan Ridge or it still has the original firmware?

When I look online for how to do this mod it looks like you also need to connect to C4 the top side of the little resister to left of your red wire.
Yes I have seen that in every photo as well. When I return home this evening I'll use a magnifying glass to look at that C3/C4 component. I'm not sure right now whether that's a resistor or capacitor. Resistors are labeled with R, but these devices look like SMD capacitors (Surface Mount Device).

Sorry it is a capacitor.
This is what I was looking at.


it is the part that concerns me. the rest of the soldering I can do. Something about pin 9 needing 3.3v also is best I can gather.

Yes! This is what I was looking for. We don’t have to worry about Pin 9. The C4 capacitor (or C3 on some models) is also connected to Pin 9. I think the article just mentions pin 9 as FYI.
