Memory Subsystem Architecture
Each Intel® Xeon® E5-4600 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 thirty-two (32) DIMMs for the server. Up to 32GB capacity DIMMs are supported for
1.0TB of memory (32 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.
DIMM slots attached to each processor socket are only available if a processor is installed in that socket.
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.
LRDIMMs and RDIMMs are distinct memory technologies and cannot be mixed within a server.
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 BL660c Gen8 Server Blade.
When HP 24GB (1x24GB) Three Rank x4 PC3L-10600R (DDR3-1333) Registered CAS-9 Low Voltage FIO Memory Kits are used, all
32 DIMM slots on the BL660c Gen8 must be fully populated with these 24GB DIMMs.
To realize the performance memory capabilities listed in this document, HP SmartMemory is required. For additional
