Memory options
IMPORTANT: This server blade 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 blade 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 blade must be the same
type.
The server model using Intel Sandy Bridge processors 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 at up to 1333 MT/s
