Mac Pro 2013 - Interconnect Board ID ?

[dickybow]

Hello

I have been experiencing many problems with a 2013 Mac Pro with unexpected power-offs and freezes. Making the system unusable.

The system was bought new sealed Dec 2017.

Under warranty I have had 1x D300 replaced, but the problem persisted.

Then another warranty repair replaced the other D300, CPU Riser Card and CPU and the Logic / Interconnect board.

However the problem is still there.

I have an inkling that the Logic / Interconnect board was not replaced despite claims that it was.

Despite the 'proof' from the genius bar work authorisation sheet - is there any way to identify the board from Apple System Report so I can prove it has not been changed ?

I took screenshots of every page of the System Report before the repairs which may prove ?


Thanks

To clarify I am referring to the below part :

I would reach out to @CodeJingle for information that may help. He literally knows every fraction of an inch of the nMP. He may be able to guide you on this.

I will PM him now and hope he doesn't mind !

I would test your home's electrical grounding. The Mac Pro (late 2013) being a solid block of metal it is very fragile when it comes to self-shock.

If you are using NVMe then please make sure you are not doing bootcamp on the drive. If you still have your old SSD then try swapping and see if the crashes stop.

I don't think the logic board itself shows a unique identifier on it. Though I am sure several of the chips on board contain unique identifiers. Unfortunately you would need to have properly documented your logic board originally to know if it was swapped or not as part of the servicing. You could do anything to mark the board, like a fine-tip permanent marker make a few tiny marks on the board, to know if the board was changed.

If none of those things work then run the full set of tests for Apple diagnostics. ASD I think? You have to 'find' it online.
