Memory Subsystem Architecture
Each AMD Opteron family processor socket contains four memory channels that support three DIMMs each for a total of twelve (12)
DIMM per installed processor or a grand total of twenty-four (24) DIMMs for the server. Up to 32GB capacity DIMMs are supported for
768GB of memory (24 DIMM slots x 32GB per DIMM).
General Memory Population Rules and Guidelines:
White DIMM slots denote the first slot of a channel. For 1 DPC (DIMM per channel) populate white slots only.
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 are supported up to 3 DIMMs per channel.
The DL385p Gen8 RBSU has options to set memory for Performance or Power modes. In Performance Mode all memory whether
1.35V DIMMs or 1.5V DIMMs will be set to 1.5V. In Power Mode all memory whether 1.35V or 1.5V will be set to 1.35V for power
savings.
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 and memory configuration.
The maximum memory capacity is a function of the memory type and number of installed processors.
HP memory from previous generation servers is not qualified on the DL385p Gen8 Server. Certain HP SmartMemory
features such as memory authentication and enhanced performance may not be supported.
To realize the performance memory capabilities listed in this document, HP SmartMemory is required. For additional
information, please see the HP SmartMemory QuickSpecs at:
