DIMM slot population order
CPUMEMRs are populated in four steps. In each step, four DIMM memory
modules are added. At least four DIMM memory modules must be installed on
CPUMEMR #1 and #2. CPUMEMRs #3 to #8 can be left empty.
Table 3
shows the DIMM slot population order for an individual CPUMEMR and
figure 2
maps the population order to the location of the DIMM slots on the
CPUMEMR.
