Memory Subsystem Architecture
The memory subsystem in this server blade is divided into 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 per processor is required.
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 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.
RDIMMs and LRDIMMs cannot be mixed.
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 BL465c 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:
http://h18000.www1.hp.com/products/quickspecs/14225_na/14225_na.html.
For memory population rules and additional memory guidelines, please see the BL465c Gen8 user guide at
http://www.hp.com/support.
NOTE: Mixing 1.25V and 1.5V DIMMs is not allowed. Mixing DIMMs with different voltage levels will result in the higher voltage level
being used resulting in higher power consumption.
