DIMM Configuration

In this illustration of the DIMM slots, the Oracle ILOM legacy targets for the DIMMs are provided across the top, and the Oracle ILOM /System targets for the DIMMs are provided across the bottom.

For example, the slot on the far left has the Oracle ILOM legacy target of /SYS/MB/P1/D0. This same slot has the Oracle ILOM /System target of /System/Memory/DIMMs/DIMM_0.

Number Oracle ILOM Target 1 /SYS/MB/P0/D(0-5) 2 /SYS/MB/P0/D(6-11) 3 /SYS/MB/P1/D(0-5) Note -  These slots are not functional in a single-processor configuration. 4 /SYS/MB/P1/D(6-11) Note -  These slots are not functional in a single-processor configuration. 5 /System/Memory/DIMMs/DIMM_(0-11) 6 /System/Memory/DIMMs/DIMM_(12-23) Note -  These slots are not functional in a single-processor configuration.

When you add or remove DIMMs to the motherboard, follow these guidelines:

• You can configure an odd number of DIMMs, however an equally-balanced even number of DIMMs provides better performance.

• When you add DIMMs in pairs, the pair should be of the same part number.

• If you are mixing DIMM capacities, install the largest capacities first, then consecutively smaller capacities.

• If a slot is empty, install a DIMM filler. With the single-processor configuration, all DIMM slots on P1 must be filled with filler panels.

  Caution  -  Overheating hazard. There must be no empty DIMM slots.

• Populate the DIMMs in the order described in DIMM Population Guidelines for Dual-Processor Servers
