Some DIMM installation guidelines are summarized below:
For the HP ProLiant BL280c G6 server with twelve (12) memory slots:
There are three (3) channels per processor; six (6) channels per server
There are two (2) DIMM slots for each memory channel; twelve (12) total slots.
Memory channel 1 consists of the two (2) DIMMs that are closest to the processor
Memory channel 3 consists of the two (2) 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
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 processor
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 1,3, 2, 4; on a 2DPC system
Low Voltage DIMMs can only be used with Intel Xeon 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
