1.6.2 Memory Configurations

The Intel 82865PE MCH component provides two features for enhancing memory throughput:
•
Dual Channel memory interface. The board has two memory channels, each with two DIMM
sockets, as shown in Figure 3
•
Dynamic Addressing Mode. Dynamic mode minimizes overhead by reducing memory
accesses
Table 6 summarizes the characteristics of Dual and Single Channel configurations with and
without the use of Dynamic Mode.
