Sun Fire X4100/X4200
The DIMM population rules for Sun Fire X4100/X4200 servers are as follows:
■ Each CPU can support a maximum of four DDR1 DIMMs.
■ Each pair of DIMMs must be identical (same manufacturer, size, and speed).
■ CPUs with only a single pair of DIMMs must have those DIMMs installed in that
CPU’s white DIMM slots (0 and 1). See
FIGURE 3-51.
■ See TABLE 3-1 for supported DIMM configurations for Sun Fire X4100/X4200
servers.
■ The DIMM slots are paired and the DIMMs must be installed in pairs (0 and 1;
2 and 3). The memory sockets are colored black or white to indicate which slots
are paired by matching colors.
Note – The system reports individual DIMM numbers when a memory fault
happens.

The DIMM population rules for Sun Fire X4100 M2/X4200 M2 servers are listed here:
■ Each CPU can support a maximum of four DDR2 DIMMs.
■ Each pair of DIMMs must be identical (same manufacturer, size, and speed).
■ CPUs with only a single pair of DIMMs must have those DIMMs installed in that
CPU’s white DIMM slots (3 and 2). See
FIGURE 3-52.
■ See TABLE 3-2 for supported DIMM configurations for Sun Fire X4100 M2/X4200
M2 servers.
■ The DIMM slots are paired and the DIMMs must be installed in pairs (0 and 1; 2
and 3). The memory sockets are colored black or white to indicate which slots are
paired by matching colors.
