In case anyone else needs the same info I found this https://forums.servethehome.com/index.php?threads/used-epyc-7601-post-code-78.29841/
"code 78 on an Asrock Rack EPYCD8-2T"
"I wanted to implicate POST code 78 (at least on Asrock and other AMI Aptio V based boards) to this exact problem to help others who purchase pulled EPYC CPUs."
still looking to see if there are other vendor codes.

doesn't that depend on how it's broken? like if something was wrong with the memory controller on the cpu package it would in theory stop at a code that indicates it couldn't access memory
i do not know how the BIOS code comes into the processor, at intel the PCH does this job.
but i know the POST code is written to Port80, this is a memory address.
if the memory controller is broken....
for instance if one of the pads or pins on the memory bus is broken or not making good contact, maybe even just plain dirty you could get code 55 for memory even though it might not be on the memory side it could be on the cpu.
