Overview
When you choose HPE DDR4 SmartMemory, you get great performance, reliability, and efficiency that provides the compatibility, 
capacity and bandwidth you need to productively manage your expanding workload with the HPE ProLiant Gen9 s 
Family, Synergy and Blade Systems. The quality and reliability of DRAM are more important now than ever, as data center trend 
such as server virtualization, cloud computing, the use of large database applications, have all increased the need for higher capacity 
memory with greater uptime.
HPE SmartMemory goes through rigorous qualification and testing processes that unlock extended memory performance features 
available only with Hewlett Packard Enterprise Gen9 servers. This extensive testing 
compatible with and optimized for HPE servers.

and tower UPS products; these items will be covered 
•  If only one processor is installed in a two-processor system, only half of the DIMM slots are available. 
: 
•  To maximize performance, it is recommended to balance the total memory capacity between all 
installed processors and load the channels similarly whenever possible. 
•  When two processors are installed, balance the DIMMs across the two processors. 
•  White DIMM slots denote the first slot to be populated in a channel. 
•  Place the DIMMs with the highest number of ranks in the white slot when mixing DIMMs of different 
ranks on the same channel. 
•  Mixing of DIMM types (UDIMM, RDIMM, and LRDIMM) is not supported. 
•  Mixing the 128GB LRDIMM with other capacities is not supported. 
•  Quad rank LRDIMMs are capable of up to 3DPC. 
•  DIMMs of different speeds may be mixed in any order; the server will select a common optimal speed. 
•  The maximum memory speed is a function of the memory type, memory configuration, and processor 
model. 
•  The maximum memory capacity is a function of the memory type and number of installed processor. 
•  To enable Mirrored Memory mode, the system allocates half of the installed memory as system 
memory and the remaining half as mirrored memory. All memory channels must be configured 
identically. 
•  Only an RDIMM can be mixed with HPE NVDIMM 
•  When installing NVDIMM(s) on the same memory channel as RDIMM(s), populate the RDIMM(s) first
