Memory population guidelines
Some DIMM installation guidelines are summarized below:
For this server with twelve (12) memory slots:
There are two (2) channels per processor; four (4) channels per server
There are three (3) DIMM slots for each memory channel; twelve (12) total slots
Memory channel 2 consists of the three (3) DIMMs that are closest to the processor
Memory channel 1 consists of the three (3) DIMMs that are furthest from the processor
DIMM slots that are white should be populated first
DIMM slots are numbered sequentially (1 through 6) for each processor. The supported AMP modes use the alpha assignments
for population order, and the slot numbers designate the DIMM slot ID for spare replacement.
Do not mix Ultra Low Voltage DIMMs memory (ULVDIMMs) with Registered memory (RDIMMs)
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

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 1066MHz If you
install 1x 1066MHz DIMM in channel 1 and 5x 1333MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the other channels, the
