Populating DIMMs for Optimal System Performance

Optimal performance is generally achieved by populating the DIMMs so that the memory is
symmetrical, or balanced. Symmetry is achieved by adhering to the following guidelines:
In single-processor systems, populate DIMMs of the same size in multiples of six.
■
In dual-processor systems, populate DIMMs of the same size in multiples of twelve.
■
Populate the DIMM slots in the order described in the following sections.
■
The following sections provide an example of how to populate the DIMM slots to achieve
optimal system performance.

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.
Not all possible configurations are shown here.
