Memory Configurations - Intel D875PBZ Quick Start Manual

• Memory Configurations

The Intel 82875P 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 minimises overhead by
reducing memory accesses
Table 4 summarises the characteristics of Dual and Single Channel
configurations with and without the use of Dynamic Mode.
