QuickSpecs
Memory
Memory Subsystem Each Intel® Xeon® E5-2600v3 family processor socket contains four memory channels per installed processor with
Architecture three DIMMs per channel for a total of twelve (12) DIMMs or a grand total of twenty-four (24) DIMMs for the server.
Memory Population
guidelines
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.
. A minimum of one DIMM is required per server.
. 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.
. When two processors are installed, balance the DIMMs across the two processors.
Populate DIMMs from heaviest load (quad-rank) to lightest load (single-rank) within a channel. Heaviest load
.
(DIMM with most ranks) within a channel goes furthest from the processor.
. Do not mix RDIMMs or LRDIMMs.
. LRDIMMs are supported up to 3 DIMMs per channel.
. 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.
