Post code + display not powering on (new 12th gen)

@turova, see the post linked here: Speaking of POST errors - seeking documentation - #2 by nrp

If I am converting it properly it looks like 0x80, which from the linked page resolves to this:
#define PEI_MEMORY_INSTALL 0x80 // Simple Memory test

Do you have any other RAM with which to test?
