  Now that I am an owner, I would like to know more about the hardware inside my machine, without having to dismantle it.

  Is there anywhere I can find information about the mainboard being used inside the M6 Ultra? For instance, is the limitation on memory speed at 4800 MT/s DDR5 related to a mainboard limitation of some kind?

  So far, it appears that the mainboard is likely to be an "SU ARB19D", but I have not found any way to confirm that without dismantling my M6 Ultra.

  I wonder what company manufactures the "SU ARB19D" mainboard for use by mini-pc builders. It seems obvious that they are based in China.
