Intel Desktop Board D865PCD Technical Product Specification

1.5.1Memory Configurations

The Intel 82865P MCH component provides two features for enhancing memory throughput:

Dual Channel memory interface. The board has two memory channels, each with a single DIMM socket, as shown in Figure 3

Dynamic Addressing Mode. Dynamic mode minimizes overhead by reducing memory accesses

Table 5 summarizes the characteristics of Dual and Single Channel configurations with and without the use of Dynamic Mode.
