1.5.1 Memory 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.
