Memory Subsystem Architecture
Each Intel® Xeon® E5-2600 family processor socket contains four memory channels that support two DIMMs each for a total of eight
(8) DIMM per installed processor or a grand total of sixteen (16) DIMMs for the server. Up to 32GB capacity DIMMs are supported for
512GB of memory (16 DIMM slots x 32GB per DIMM).
Memory Population Rules and Guidelines
:
A minimum of one DIMM is required per processor.
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.
DIMM sizes can be mixed in channel. To maximize performance, it is recommended to balance the total memory capacity
between all installed processors and to load the channels similarly whenever possible.
RDIMMs operating at either 1.35V or 1.5V may be mixed in any order, but the system will power them at the higher voltage.
LRDIMM, RDIMM and UDIMMs are all distinct memory technologies and cannot be mixed within a server. The majority of ProLiant
Gen8 servers support RDIMM, UDIMM and LRDIMM.
The Intel Xeon E5-2620 processor does not support DIMMs at 1.35V.
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 processors.
HP memory from previous generation servers is not compatible with the WS460c Gen8 Server Blade.
To realize the performance memory capabilities listed in this document, HP SmartMemory is required. For additional
information, please see the HP SmartMemory QuickSpecs at:
