DDR3 memory population guidelines
NOTE: Charts do not represent all possible memory configurations.
For detailed memory configuration rules and guidelines, please use the Online DDR3 Memory Configuration Tool:
Some DIMM installation guidelines are summarized below:
For servers with nine (9) memory slots;
There are three (3) channels per processor, per server.
There are three (3) DIMM slots for each memory channel; nine (9) 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).
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.

NOTES:
PC3-10600 DIMMs have a maximum speed of 1333MHz. PC3-8500 DIMMs have a maximum speed of 1066MHz
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, the maximum speed will be
