Memory Modules
There are eight DIMM slots on the system board, with four DIMM slots adjacent to
each CPU socket. Because memory is installed as matched DIMM pairs, these slots
are divided into two DIMM banks per CPU (see
FIGURE 5-2
for their locations).
Therefore, CPU0 has four corresponding DIMM slots divided into two banks, Bank0
and Bank1. CPU1 has four corresponding DIMM slots divided into two banks,
Bank0 and Bank1.
