Don't mean to hijack this thread, but are there any updates to this?

I also have a 5,1, 12 core 3.46, AMD 580 nitro, 64g ram, oclp 2.2.0, sequoia 15.2 - that freezes randomly. I've re-seated/re-pasted the CPU's and Northbridge (clips are fine) and still the same issue.

Last week, my neighbor gave me a clean 5,1, 12 core 2.66, that he no longer uses, and I switched out that tray into mine and it still freezes. For me, that removes the cpu tray from the equation.

It'll be on sometimes for 30 mins, sometimes 4-5 hours and it will freeze.

I'm wondering now, if maybe it's the power supply or maybe the efi?

Here's my kernel panic report -

Thanks for any insight.

Install Mojave without OC/OCLP and see if the same happens. Run AHT/ASD.
 
The donor Mac Pro I was given, has HIgh Sierra on the ssd. Would it be easier to upgrade that to Mojave and swap out the ssd's to see if I still get the freezes?

Thanks tsialex

I'd nuke the disk and do a completely clean install.

If you don't start from scratch you won't be sure that the problem is hardware or software. With this type of problem you have to be completely sure about each step.
 
Ah, that makes complete sense. I'll do this over the next few days and report back. Thanks again tsialex!
