Dimm Numbering - HP ProLiant xw25p User Manual

30 HP ProLiant BL25p Server Blade User Guide
Certain configuration requirements exist with single- and dual-rank DIMMs that
allow the architecture to optimize performance. A dual-rank DIMM is similar to
having two separate DIMMs on the same module. Although only a single DIMM
module, a dual-rank DIMM acts as if it were two separate DIMMs. The primary
reason for the existence of dual-rank DIMMs is to provide the largest capacity
DIMM given the current DIMM technology. If the maximum DIMM technology
allows for creating 2-GB single-rank DIMMs, a dual-rank DIMM using the same
technology would be 4-GB.
