The server memory control subsystem selects the proper rank within the DIMM when writing to or reading

from the DIMM.

Dual-rank DIMMs provide the greatest capacity with the existing memory technology. For example, if current

DRAM technology supports 2-GB single-rank DIMMs, a dual-rank DIMM would be 4 GB.

DIMM identification

To determine DIMM characteristics, use the label attached to the DIMM and the following illustration and

table.
