Processor/Memory Subsystem
3.1 Introduction
This chapter describes the processor/memory subsystem. This systems support the AMD
Phenom, Athlon, and Sempron processor families. As shown in Figure 3-1, these processors use
an integrated DDR2 memory controller and communicate with the chipset through the
HyperTranport interface (I/F).
