Memory options

NOTE: Memory configurations listed do not apply to 'Factory Integrated Models'.

For detailed memory configuration rules and guidelines, please use the Online DDR3 Memory Configuration Tool:

Click here to access the 'HPE Server Memory Configurator'.

Some Dual In-line Memory Module (DIMM) installation guidelines are summarized below:

  • For servers with eighteen (18) memory slots:

    • There are three (3) channels per processor; six (6) channels per server

    • There are three (3) DIMM slots for each memory channel; eighteen (18) total slots

    • Memory channel 1 consists of the three (3) DIMMs that are closest to the processor

    • Memory channel 3 consists of the three (3) DIMMs that are furthest from the processor

  • DIMM slots that are white should be populated first

  • Do not mix Unbuffered memory (UDIMMs) with Registered memory (RDIMMs)

  • Do not install DIMMs if the corresponding processor is not installed

  • If only one processor is installed in a 2 CPU system, only half of the DIMM slots are available

  • To maximize performance, balance the total memory capacity between all installed processors

  • It is not required, but it is recommended to load the channels similarly if possible

  • User can only have up to eight (8) ranks installed per channel

  • When using quad-rank DIMMs, only 2 DIMMs can be installed per channel. The combinations are as follows: 2 quad-rank DIMMs,1 quad-rank DIMM + 1 dual-rank DIMM or 1 quad-rank DIMM + 1 single-rank DIMM

  • User can only install two quad-rank DIMMs per channel

  • User can only install two UDIMMs per channel; if available, the third slot in the channel must remain empty

  • 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 chipset

  • For memory mirroring mode, channel 3 must be unpopulated. Channels 1 and 2 are populated identically

  • For lock-step mode, channel 3 must be unpopulated. DIMMs in channels 1 and 2 will be installed in pairs. The paired slots will be1,4; 2,5; 3;6 on a 3DPC system or 1,4; 2,5; on a 2DPC system

  • Low Voltage DIMMs can only be used with Intel Xeon processor 5600 series processors

  • If mixing DIMM voltage is a requirement, please note that the DIMMs will run at 1.5 V since all 1.35 V are capable of supporting1.5 V operations

  • **3DPC: LV/Std voltage runs at 800

NOTE:

  • Mixing DIMM speeds is allowed, but the system processor speed rules always override the DIMM capabilities

  • If user do mix DIMM speeds, the memory bus will default to the minimum clock rate of all DIMMs in the system - even if the slowerDIMM is on the other processor

  • If user install 1x 1066 MHz DIMM in channel 1 and 1x 1333 MHz DIMM in channel 2, user still run at 1066 MHz

  • If user install 1x 1066 MHz DIMM in channel 1 and 5x 1333 MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the other channels,user run at 1066 MHz

  • If user install 3DPC in one channel (if applicable) and 1DPC in all other channels, user run at 800 MHz

  • References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc.
