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 higher 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.
