DRAM DIMM rank classification label

A DIMM rank is a set of memory chips that the system accesses while writing or reading from the
memory. On a multi-rank DIMM, only one rank is accessible at a time.
To determine the rank classification of a DRAM DIMM, use the label attached to the DIMM, as shown
in Figure 11-1.
