DIMM slot locations
DIMM slots are numbered sequentially (1 through 12) for each processor. The supported AMP modes use the
letter assignments for population guidelines.
NVDIMM identification
NVDIMM boards are blue instead of green. This change to the color makes it easier to distinguish NVDIMMs
from DIMMs.
