NOTE: If more than one Quad rank DIMM is installed within a channel (DIMM1 & DIMM4, DIMM2 & DIMM5, DIMM3 & DIMM6)
then the maximum DDR3 speed is reduced to 800 MHz. Spreading Quad Rank memory modules accross multiple channels is
recommended.
NOTE: DDR3 DIMMs have 240 pins, the same number as DDR2, and are the same size, but are electrically incompatible and
have a different key notch location.
Memory Subsystem
The memory subsystem consists of three DDR3 memory channels attached to each processor. All single-processor configurations
have six DIMM slots (two per channel) attached to the primary processor located on the system board. Dual-processor
configurations require an optional riser card that contains the secondary processor and the DIMMs associated with the secondary
processor. There are six DIMM slots on the riser, for a total of twelve DIMMs in the system.
DIMM slot configuration for a single processor or a second processor on the riser.
Memory Slots
There are six memory slots on the system board. The slots are numbered DIMM1 through DIMM6. DIMM1 is furthest from the
processor.
