The memory subsystem in this server can support LRDIMMs or RDIMMs:

• RDIMMs offer lower latency in one DIMM per channel configurations and (relatively) low power

consumption. They 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.

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.

The server supports the following DIMM speeds:

• Single- and dual-rank PC3-10600 (DDR-1333) RDIMMs operating at up to 1333 MT/s

• Single- and dual-rank PC3-12800 (DDR-1600) RDIMMs operating at up to 1600 MT/s

• Quad-rank PC3L-10600 (DDR3-1333) LRDIMMs, operating as dual-rank DIMMs, at up to 1333 MT/s

Depending on the processor model, the number of DIMMs installed, and the voltage(s) of the DIMMs

installed, the memory clock speed can be reduced from the DIMMs' native speed. See the following tables
