Lenovo M75s Gen 2 supported CPUs

[trotskito]

Hello everyone,

I have this SFF Lenovo M75s Gen 2 PC. Mine came with a Ryzen 4600G and, according to this data sheet, the system supports a number of AMD Renoir, Matisse and Picasso cpus. Strangely, Lenovo provides two different BIOS roms, one for Renoir/Picasso chips and other for Matisse ones.

According to MC Extractor, the Matisse BIOS file recognizes the following CPUIDs:

CPUID signature A20F10 stands for Ryzen 5600X, which is not "officially" supported in Lenovo's specs. Does it mean the mobo should be compatible with it? Does the "No" in the "Last" column mean it is not in some way?

Thanks in advance!
