. 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.
. Do not mix LRDIMMs with any other DIMM type (RDIMM, LVDIMM).
. RDIMM population is limited to a maximum of eight logical ranks per channel. Therefore, only two quad
rank RDIMMs are supported per channel. If there are more than eight physical ranks per channel,
LRDIMMs rank multiplication provides support for three DIMMs per channel.
. • Lockstep mode requires specific population requirements. See lock-step configuration below for more
information.
NOTE: UDIMMs are not supported. This server does not support mixing LRDIMMs, RDIMMs, or
UDIMMs. Attempting to mix any combination of these DIMMs can cause the server to halt during
BIOS initialization. For detailed memory configuration rules and guidelines, use the Online DDR4
Memory Configuration Tool on the Hewlett Packard Enterprise website
(http://www.hp.com/go/ddr3memory-configurator).
