Processor/Memory Subsystem
3.1 Introduction
This chapter describes the processor/memory subsystem. These systems feature the Intel
Pentium 4 processor and the 915G chipset (Figure 3-1). The dx6100 and dc7100 models support
PC2700 or PC3200 DDR memory and come standard with PC3200 DIMMs installed. The
dx6120 models support PC2-4300 DDR2 DIMMs only.
