DIMM Population Rules

Observe the following guidelines when installing or replacing DIMMs:

•Each CPU supports four memory channels.

–CPU1 supports channels A, B, C, and D.

–CPU2 supports channels E, F, G, and H.

•Each channel has two DIMM slots (for example, channel A = slots A1 and A2).

–A channel can operate with one or two DIMMs installed.

–If a channel has only one DIMM, populate slot 1 first (the blue slot).

•When both CPUs are installed, populate the DIMM slots of each CPU identically.

–Fill blue slots in the channels first: A1, E1, B1, F1, C1, G1, D1, H1

–Fill black slots in the channels second: A2, E2, B2, F2, C2, G2, D2, H2

•Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized. In a single-CPU configuration, populate the channels for CPU1 only.
