DIMM installation order
Note
DIMM installation order in 1-CPU configuration differs from that in 2-CPU configuration.
If CPU2 is not installed, CPU2_DIMM1 to CPU2_DIMM6 are disabled.
In 1-CPU configuration, install a DIMM starting from the smallest slot number.
In 2-CPU configuration, install a DIMM starting from the smallest slot number of each CPU.
Installation order depends on combination of DIMMs to be installed. See the table below to find allowable
combination of DIMMs, and install DIMMs starting from the largest capacity and from the smallest slot number.
