Populating DIMMs in Single-Processor Systems for Optimal System Performance

In single-processor systems, install DIMMs only into DIMM slots associated with processor 0 (P0). Starting with slot P0 D7, first fill the black slots, and then fill the white slots, as shown in the following figure.

image:Figure showing the DIMM population order for single-processor                     systems.

The following table describes the proper order in which to populate DIMMs in a single-processor system using the numbered callouts in the above figure, and the DIMM slot labels (D0 through D11).

Population Order
Processor/DIMM Slot
Populate black slots first in the following order:
  1. P0/D7

  2. P0/D4

  3. P0/D9

  4. P0/D2

  5. P0/D11

  6. P0/D0

After black slots have been populated, populate white slots in the following order:
  1. P0/D6

  2. P0/D5

  3. P0/D8

  4. P0/D3

  5. P0/D10

  6. P0/D1
