Memory options
IMPORTANT: This server does not support mixing LRDIMMs or RDIMMs. Attempting to mix any
combination of these DIMMs can cause the server to halt during BIOS initialization.
The memory subsystem in this server can support LRDIMMs and RDIMMs:
•
RDIMMs offer 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 PC4-2133 (DDR4-2133) RDIMMs operating at up to 2133 MT/s
•
Quad-rank PC4L-2133 (DDR4-2133) LRDIMMs operating at up to 2133 MT/s
Speed and capacity

RDIMM
Single-rank 8 GB 2133

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

HP SmartMemory
HP SmartMemory authenticates and unlocks certain features available only on HP Qualified memory and
verifies whether installed memory has passed HP qualification and test processes. Qualified memory is
performance-tuned for HP ProLiant and BladeSystem servers and provides future enhanced support through
HP Active Health and manageability software.
Memory subsystem architecture
The memory subsystem in this server is divided into channels. Each processor supports four channels, and
each channel supports three DIMM slots.
