For detailed memory configuration rules and guidelines, please use the Online DDR3 Memory Configuration Tool:
www.hp.com/go/ddr3memory-configurator
General Guidelines:
White DIMM slots denote the first slot of a channel. For 1 DPC (DIMM per channel) populate white slots only.
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, balance the total memory capacity between all installed 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 UDIMMs, RDIMMs or LRDIMMs
Quad rank LR DIMMs are supported at 3 DIMMs per channel.
DIMMs of different voltages (1.35V & 1.5V) may be mixed in any order
The system will power them at the higher voltage
DIMMs of different speed grades may be mixed in any order
The system will select a common optimal speed
Memory speed is a function of the processor QPI bus speed.
Population Guidelines:
There are four (4) channels per processor; eight (8) channels per server
There are three (3) DIMM slots for each memory channel; twenty-four (24) total slots
Memory channels1 and 3 consists of the three (3) DIMMs that are furthest from the processor
Memory channel 2 and 4 consists of the three (3) DIMMs that are closest to the processor
