1.7.1 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 4
• Dynamic Addressing Mode. Dynamic mode minimizes overhead by reducing memory
accesses
Table 7 summarizes the characteristics of Dual and Single Channel configurations with and
without the use of Dynamic Mode.

Throughput
Level Configuration Characteristics
Highest Dual Channel with Dynamic Mode All DIMMs matched
(Example configurations are shown in Figure 5)
Dual Channel without Dynamic Mode • DIMMs matched from Channel A to Channel B
• DIMMs not matched within channels
(Example configuration is shown in Figure 6)
Single Channel with Dynamic Mode Single DIMM or DIMMs matched within a channel
(Example configurations are shown in Figure 7)
Lowest Single Channel without Dynamic Mode DIMMs not matched
(Example configurations are shown in Figure 8)
