IMPORTANT:
This server does not support mixing LRDIMMs or RDIMMs. Attempting to mix any combination of these
DIMMs can cause the node to halt during BIOS initialization.
The memory subsystem in this node 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.
