System Overview
2.4 System Architecture
The systems covered in this guide feature an architecture based on the Intel Pentium 4 processor
and the Intel 945G chipset (Figure 2-14). These systems allow processor upgrading with the Intel
Pentium 4 family and offer flexibility in expansion capabilities.
All systems covered in this guide include the following key components:
■
Intel Pentium 4 with Hyper-Threading technology, 32-KB L1 cache and 1-MB L2 cache.
■
Intel 945G chipset - Includes 82945G GMCH north bridge and 82801 ICH8 south bridge
including an integrated graphics controller, dual-channel DDR2 SDRAM controller, serial
and parallel ATA controllers, USB 2.0 controller, and PCI controller supporting PCI 2.3
devices.
■
SMC SCH5307 super I/O controller supporting PS/2 keyboard and mouse peripherals
■
ALC260 audio controller supporting line in, line out, microphone in, and headphones out
■
Broadcom BCM5752 10/100/1000 network interface controller
The 945G chipset provides a major portion of system functionality. Designed to compliment the
latest Intel Pentium 4 processors, the chipset serves the processor through a 533/800/1066-MB
Front-Side Bus (FSB). Communication between the GMCH and ICH8 components occurs
through the Direct Media Interface (DMI). The SFF, ST, MT, and CMT form factors use the
integrated graphics controller of the 82945G that may be upgraded through a PCI Express x16
graphics slot. All systems include at least one PCI 2.3 slot, and feature as standard a serial ATA
(SATA) hard drive. The USDT models feature support for a MultiBay device through a legacy
parallel ATA 100 interface.
Table 2-3 lists the differences between models.
Notes:
[1] Supports only an ADD2 card in the reverse-layout.
[2] Slot not accessible if PCI 2.3 full-height riser is installed.
[3] Requires adapter.
[4] 2nd serial port requires adapter
