Installing Memory Modules
Memory Configuration Rules
When you install memory, follow these configuration rules:
■
All memory must be installed on the system board as matched DIMM pairs,
where each DIMM in the pair shares the same characteristics.
■
All DIMM pairs on the system board must share the following characteristics:
■
Vendor
■
Type
■
Capacity
■
Speed
■
On a single-processor system board, install the first DIMM pair in the memory
bank next to the CPU. For example, on a single-processor system board, the CPU
is installed in the CPU0 slot. Therefore, you must install the first DIMM pair in
CPU0 DIMM Bank0 (see
FIGURE 5-2
).
■
A dual-processor system board must have a minimum of one DIMM pair
installed in CPU0 DIMM Bank0 (see
FIGURE 5-2
).
■
When installing additional memory, see
TABLE 5-1
and
TABLE 5-2
for the proper
installation order of the DIMM pairs.
