MP 7,1 Panic: Memory ID 0x6?

[choreo]

I have been getting tons of panics on my Mac Pro ever since I got it. A lot of the freezes and restarts could be attributed to either Adobe or the w5700x GPU, but most of those seem to resolved themselves over the past year or so.

Nearly all of the panics I get for the past few months start out reading just like the snippet pasted below. I notice it ALWAYS mentions Memory ID: 0x6. Does that maybe refer to a physical RAM stick location. I have had 3rd party RAM installed since the beginning and just wondered if it could be something simple like one RAM module?

I have run numerous ram tests and everything always passes.

What is important from the crash log above is the CATERR.

CATERR stands for Intel Catastrophic Error, something is crashing the CPU. I'd check with Apple support to see if they can track what is going on.

Alex,

Already did that when I first received my new Mac Pro in July 2020 and started getting all these and other panics. Went back and forth for months with Apple Support trying everything imaginable and even though it was way past my return window, once they decided it was the Logic Board, they just replaced my entire Mac Pro with another new retail unit. The new one came in November 2020, and have been fighting with auto-restarts again ever since.

Some of the panic reports were really long and verbose, but the past couple months they are all very similar short reports - all of them starting out like my example. Most occur either during sleep or upon waking from sleep, but occasionally when all I have open is a browser window in Safari or when launching Quicktime.

Never recall a single panic with my previous 2012 Mac Pro in all those years - had over 300 documented with this new Mac Pro in the past year and a half. Sometimes 4 a day - sometimes once a week with almost identical use patterns.

Maybe your problem is not on the Mac Pro itself, but on peripherals or even a incorrectly set-up power socket. I know that some TB crashes can generate CATERR. Also, see if everything you are connecting is on the same grounding.
