820-00840 CPU MCA Error

[Maltinho]

Hey,

A1708 820-00840, machine boots most of the time flawless, sometimes it takes some minutes to wake up. When it takes some time, theres an error reported, find attached. This machine gets pretty warm, in repair wiki i cant find a specific example as its not "random crashing". Inspected the board and it looked ok. Maybe someone can help from the attached error note?

You should discard software error first.
Remove SSD and boot USB test macOS.
You can also check with another internal SSD.

Installed new OS on a new SSD. Still getting this issue. When the Macbook does boot, everything works. But reboot takes time and some tries. This was the latest code
