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

You can only have up to eight (8) ranks installed 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

No mixing DIMM voltage; all DIMMs must be the same voltage

DIMM Type ->			Registered DIMMs (RDIMMs)				Unbuffered with ECC DIMMs (UDIMMs)
DIMM Rank ->		Dual Rank (2R)			Quad Rank (4R)		Single Rank (1R)		Dual Rank (2R)

* - not supported by HP at this time.
NOTES:

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

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

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