DIMM Population Order for Single-Processor Systems
In single-processor systems, DIMMs should only be installed into DIMM sockets
associated with processor 0 (P0) starting with P0 D0, first filling the blue sockets and
then the white. This DIMM population order is illustrated in FIGURE: DIMM
Population Order on page 65.
The following table describes the order in which the DIMM sockets should be
populated in single-processor systems. The figure callouts in column two of the table
refer to the callouts in FIGURE: DIMM Population Order on page 65.
DIMM Population Order for Dual-Processor Systems
In dual-processor systems, DIMMs should be installed into DIMM sockets starting
with P0 D0 and then alternating between sockets associated with processor 0 (P0)
and matching sockets for processor 1 (P1), first filling the blue sockets and then the
white. This DIMM population order is illustrated in FIGURE: DIMM Population
Order on page 65.
The following table describes the order in which the DIMM sockets should be
populated in dual-processor systems. The figure callouts in columns two and four of
the table refer to callouts in FIGURE: DIMM Population Order on page 65.
