HP ProLiant DL360p Gen8 Server - Manual (Page 43)

Hardware options installation 43
• UDIMMs represent the most basic type of memory module and offer lower latency in one DIMM per
channel configurations and (relatively) low power consumption, but are limited in capacity.
• RDIMMs offer larger capacities than UDIMMs and include address parity protection.
• 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.
IMPORTANT: Due to thermal limitations, only one of the following components can be installed
in a server at a time:
• 10 SFF drive cage
• LRDIMM
• E5-2687W processor
All types are referred to as DIMMs when the information applies to all types. When specified as LRDIMM,
RDIMM, or UDIMM the information applies to that type only. All memory installed in the server must be the
same type.
The server supports the following DIMM speeds:
• Single- and dual-rank PC3-10600 (DDR3-1333) RDIMMs operating at up to 1333 MT/s
• Single- and dual-rank PC3-12800 (DDR3-1600) RDIMMs operating at up to 1600 MT/s
• Single- and dual-rank PC3L-12800 (DDR3-1600) RDIMMs operating at up to 1600 MT/s
• Single- and dual-rank PC3-10600 (DDR3-1333) UDIMMs operating at up to 1333 MT/s
• Single- and dual-rank PC3-14900R (DDR3-1866) RDIMMs operating at up to 1866 MT/s
• Quad-rank PC3L-10600 (DDR3-1333) LRDIMMs, operating as dual-rank DIMMs, at up to 1333 MT/s
• Quad-rank PC3L-14900 (DDR3-1866) LRDIMMs, operating as dual-rank DIMMs, at up to 1600 MT/s

Depending on the processor model, the number of DIMMs installed, and whether LRDIMMs, UDIMMs, or
RDIMMs are installed, the memory clock speed can be reduced to 1866 MT/s,1600 MT/s, 1333 MT/s,
1066 MT/s, or 800 MT/s.
