HPE ProLiant DL580 Gen9 - DIMM Population Guidelines for Memory Modes

Hardware options installation 51
The maximum memory capacity is a function of the DIMM capacity, number of installed DIMMs, memory
type, and number of installed processors.

DIMM population guidelines for Memory Modes
IMPORTANT: This server does not support mixing LRDIMMs, RDIMMs, or UDIMMs.
Attempting to mix any combination of these DIMMs can cause the server to halt during BIOS
initialization.
Observe the following guidelines for all memory modes:
• UDIMMs are not supported on this server.
• Do not mix LRDIMMs and RDIMMs.
• LRDIMMs support higher densities than single- and dual-rank RDIMMs, and higher speeds than
quad-rank RDIMMs. This support enables you to install more high-capacity DIMMs, resulting in
higher system capacities and higher bandwidth.
• White DIMM slots denote the first slot of a channel (CH 4-A, CH 9-B, CH 1-C, CH 12-D...).
• All types are referred to as DIMMs when the information applies to all types. When specified as
LRDIMM or RDIMM, the information applies to that type only. All memory installed in the server must
be the same type.
