Memory Performance Guidelines and Population Rules

This section describes the type of memory that the server requires and its effect on performance. The

section includes the following topics:

•DIMM Slot Numbering, page 3-20

•DIMM Population Rules, page3-21

•Memory Mirroring, page3-22

DIMM Slot Numbering

Figure 3-12 shows the numbering of the DIMM slots.
