Intel Desktop Board D865GSA Technical Product Specification
1.4.1 Memory Configurations
The Intel 82865G GMCH 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.
