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 minimizes overhead by reducing memory 

accesses 

Table 6 summarizes the characteristics of Dual and Single Channel configurations with and 
without the use of Dynamic Mode.
