Hp Smartmemory; Memory Subsystem Architecture - HP ProLiant ML110 Gen9 User Manual

The memory subsystem in this server 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.
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 the same type.
The server supports the following RDIMM and LRDIMM speeds:
•
Single- and dual-rank PC4-2133 (DDR4-2133) RDIMMs and LRDIMMs operating at up to 2133 MT/s

HP SmartMemory

HP SmartMemory authenticates and unlocks certain features available only on HP Qualified memory and
verifies whether installed memory has passed HP qualification and test processes. Qualified memory is
performance-tuned for HP ProLiant and BladeSystem servers and provides future enhanced support through
HP Active Health and manageability software.

Memory subsystem architecture

The memory subsystem in this server is divided into channels. The processor supports four channels, and each
channel supports two DIMM slots, as shown in the following table:
