System Architecture - HP Compaq Elite 8000 CMT Technical Reference Manual

System Overview

2.3 System Architecture

The systems covered in this guide feature an architecture based on the Intel Q45 Express chipset
(Figure 2-2). All systems covered in this guide include the following key components:
■
Intel Pentium Dual-Core, Core™ 2 Duo, Core 2 Quad, or Celeron processor.
■
Intel Q45 Express chipset - Includes Q45 GMCH and 82801 ICH10-DO
■
Super I/O (SIO) controller supporting PS/2 keyboard and mouse peripherals
■
ALC261 audio controller supporting line in, line out, microphone in, and headphones out
■
Intel 82567LM GbE network interface controller
■

The Q45 chipset provides a major portion of system functionality. Designed to complement the
latest Intel processors, the Q45 GMCH integrates with the processor through a
800/1066/1333-MHz Front-Side Bus (FSB) and communicates with the ICH10-DO component
through the Direct Media Interface (DMI). The integrated graphics controller of the Q45 on SFF
and CMT systems can be upgraded through a PCI Express (PCIe) x16 graphics slot. All systems
include a serial ATA (SATA) hard drive in the standard configuration.
Table 2-2 lists the differences between models by form factor.
