Warranty / Service
Coverage
For ProLiant servers and storage systems, this service covers HPE-branded hardware options qualified for the
server, purchased at the same time or afterward, internal to the enclosure, as well
as external monitors up to 22
inches
and tower UPS products; these items will be covered

General Memory
Population Rules
and Guidelines
:
• Install DIMMs only if the corresponding processor is installed.
• 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
and farthest from the processor, then populate the NVDIMM(s) last and closer to the processor.
