DDR3 memory population guidelines
For detailed memory configuration rules and guidelines, please use the Online DDR3 Memory Configuration Tool:
www.hp.com/go/ddr3memory-configurator
Some 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 2CPU system, only half of the DIMM slots are available
To maximize performance, balance the total memory capacity between all installed processors
I
t is not required, but it is recommended to load the channels similarly if possible
If any Quad rank DIMMs are installed, all channels are limited to only 2 DIMMs per channel
You can only install two quad-rank DIMMs per channel
You 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 be 1,4; 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 1.5V since all 1.35V are capable of
supporting 1.5V operations
