[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

Maybe I misunderstood. Can you clearly state what problem you are trying to solve?

Sorry, my bad.
I have 2 ram cards of 32gb. So 64 total. I plugged 2nd and 4th on the mobo from the left. If I boot in windows disk, they're good.
When in osx, I only have 32gb and system specs shows just one card installed. Both iMac pro and iMac 18,3 are not changing this

Edit: I managed to do that by mapping ram slots within smbios. So now I have 4 16gb slots, despite the 2 installed. Question is, will I be able to expand to 128?

I know this might be a ridiculously long winded and annoying process, but have you tried plugging peripherals in one by one, testing for a bit, and hopefully narrowing down which one causes the crash? I haven't got any TB hub, but for whatever reason it's stable at the moment on all ports. The only other thing I changed was not plugging everything in. I've got an old midi interface, beatstep, few other bit's that I daren't plug in. May well have been one of them causing the freezing? I know my system became stable after my ilok appeared to die during a freeze, I swapped the port it was in and now alls ok. Might be worth trying?

Agreed, and I will do that, but that still leaves me with the problem of a device or devices that may cause the problem, and I need said device to work. I don't really want to dump my RME interface (for example), or do without an iLok if the problem is likely to be solved by buying a TB dock...

Very clear. Before your reply I tried with iMac pro. It boots and works great, but still it shows 32gb, and memory within system info shows only one card installed (I have 2 32gb ballistix). If I boot into windows, it shows 64bg correctly.

I saw a recent post for a similar problem which was solved by the user defining 4 x 16GB DIMMS in Clover.

What version of Clover are you running? Press "A" at the Clover Boot Menu to see the version number.

Correct.

Since Clover 5103, I believe, we have not had to do this.

Sorry... Just seen your updated post above, so USB2.x traffic does go to the chipset. Given your previous answer would you recommend that the easiest course of action for me to get more stable USB 2.x devices would be to get a TB3 dock? Seems I'm not having much luck chasing down the problem (notwithstanding @boob 's suggestion earlier)

If you can borrow a Thunderbolt 3 dock, that would be best way to confirm the theory. However, retailers like Amazon have very good return policies, so one can buy a new unit as well.

Please note that we are theorizing that a Thunderbolt 3 Dock with its own independent USB 2 and USB 3 controller will alleviate the problem. This sounds reasonable, but it needs to be tested/verified.

OK. I'll pluck up the courage, bite the bullet and report back if/when I have any success...

Yep that's what I did. I edited my previous post.
I wonder if I can expand to 128 then, cause now it says that all of my 4 slots are in use

Sorry I missed that. I have 4630. Would update change anything in my efi setup?
