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.
