6.2.3.3 DIMM Ranks
To understand and configure memory protection modes properly, it is helpful to learn about
single-rank, dual-rank, and quad-rank DIMMs. Some DIMM configuration requirements are
based on these classifications.
l
A single-rank DIMM has one set of memory chips that are accessed while data is written
to or read from the memory.
l
A dual-rank DIMM is, effectively, two single-rank DIMMs on the same module, with
only one rank accessible at a time.
l
A quad-rank DIMM is, effectively, two dual-rank DIMMs on the same module, with
only one rank accessible at a time.
