Memory options
IMPORTANT:
This server does not support mixing LRDIMMs and 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 or RDIMMs:
•
RDIMMs offer address parity protection.
•
LRDIMMs support higher densities than single-rank and dual-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 of the same type.
The server supports the following DIMM speeds:
•
Single-rank and dual-rank PC4-2133 (DDR4-2133) RDIMMs operating at up to 2133 MT/s
•
Dual-rank and quad-rank PC4-2133 (DDR4-2133) LRDIMMs operating at up to 2133 MT/s
Depending on the processor model, the number of DIMMs installed, and whether LRDIMMs or RDIMMs are
installed, the memory clock speed might be reduced to 1600 MT/s.
