System Overview
2.3System 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
■AD1884A 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.

System Overview
2.3.1 Intel Processor Support
The models covered in this guide are designed to support the following processor types:
■Intel Celeron: singleand dual-core performance
■Intel Pentium Dual-Core: Dual core performance
■Intel Core2 Duo: energy-efficient dual-core performance
■Intel Core2 Quad: energy efficient quad-core design
These processors are backward-compatible with software written for earlier x86 microprocessors and include streaming SIMD extensions (SSE, SSE2, and SSE3) for enhancing 3D graphics and speech processing performance. Intel processors with vPro Technology include hardware-based tools that allow corporate IT organizations to remotely manage and protect systems.
The system board includes a zero-insertion-force (ZIF) Socket-T designed for mounting an LGA775-type processor package.
CAUTION: The USDT form factor can support a processor rated up to 65 watts. The SFF and CMT form factors can support a processor rated up to 95 watts. Exceeding these limits can result in system damage and loss of data.
The processor heatsink/fan assembly mounting differs between form factors. Always use the same assembly or one of the same type when replacing the processor. Refer to the applicable Service Reference Guide for detailed removal and replacement procedures of the heatsink/fan assembly and the processor.

The I/O controller hub (ICH10-DO) supports Intel vPro, which uses Active Management Technology (AMT). AMT is a hardware/firmware solution that operates on auxiliary power to allow 24/7 support of network alerting and management of the unit without regard to the power state or operating system. AMT capabilities include:
■System asset recovery (hardware and software configuration data)
■OS-independent system wellness and healing
■Software (virus) protection/management

2.3.4System Memory
These systems implement a dual-channel Double Data Rate (DDR2) memory architecture. All models support DDR2 800and 667-MHz DIMMs. The USDT system provides two SODIMM sockets supporting up to eight gigabytes of memory while the SFF and CMT form factors provide four DIMM sockets and support a total of 16 gigabytes of memory.
DDR and DDR2 DIMMs are NOT interchangeable.
SODIMM and DIMM components are NOT interchangeable.

System Overview
2.3.5 Mass Storage
All models support at least two mass storage devices, with one being externally accessible for removable media. These systems provide the following interfaces for internal storage devices:
USDT: two SATA interfaces
SFF: three SATA interfaces and one eSATA port
CMT: four SATA interfaces and one eSATA port
These systems may be preconfigured or upgraded with a SATA hard drive and one removable media drive such as a CD-ROM drive.
2.3.6 Serial Interface
The SFF and CMT form factors include a serial port accessible at the rear of the chassis. The SFF and CMT form factors may be upgraded with a second serial port option. The serial interface is RS-232-C/16550-compatible and supports standard baud rates up to 115,200 as well as two high-speed baud rates of 230K and 460K.
2.3.7 Universal Serial Bus Interface
All models provide ten Universal Serial Bus (USB) ports. Two ports are accessible at the front of the unit, six ports are accessible on the rear panel, and two ports are accessible through a header on the system board. The SFF and CMT form factors support a media card reader module that connects to the internal header. These systems support USB 1.1 and 2.0 functionality on all ports.
BIOS Setup allows for the disabling of USB ports individually or in groups. In order to secure the system against a physical attack, ports may be disabled even if there is nothing physically connected to them, such as the two front ports for the media card reader module when the module is not present.
2.3.8 Network Interface Controller
All models feature an Intel gigabit Network Interface Controller (NIC) integrated on the system board. The controller provides automatic selection of 10BASE-T, 100BASE-TX, or 1000BASE-T operation with a local area network and includes power-down, wake-up, Alert-On-LAN (AOL), Alert Standard Format (ASF), and AMT features. An RJ-45 connector with status LEDs is provided on the rear panel.

All systems include a legacy VGA connector and a DisplayPort connector and support dual monitor operation. The DisplayPort includes a multimode feature that allows a DVI or VGA adapter to be connected to the DisplayPort.
These systems also include two PCIe graphics slots (one x16, one x4/x16 connector) to ensure full graphics upgrade capabilities.
2.3.10 Audio Subsystem
These systems use the integrated High Definition audio controller of the chipset and the ADI AD1884A High Definition audio codec. HD audio provides enhanced audio performance with higher sampling rates, refined signal interfaces, and audio processors with increased signal-to-noise ratio. The audio line input jack can be re-configured as a microphone input, and multi-streaming is supported. These systems include a 1.5-watt output amplifier driving an internal speaker, which can be muted with the F10 BIOS control. All models include front panel-accessible stereo microphone input and headphone output audio jacks.
