CPU
Supports Intel
®
Socket 478 Pentium
®
4 (Willamette / Northwood) 1.4GHz~2.8GHz+ with 400/533MHz
Front Side Bus (FSB)
designed for
Socket 478 technology.
Chipset
The 845PE chipset contains two core components designed for the desktop platform: the 845PE Graphics Memory Controller Hub (GMCH),
and the Intel I/O Controller Hub 4 (ICH4). These components are interconnected via an Intel proprietary interface called Hub Interface. The
Hub Interface is designed into the 845PE chipset to provide an efficient, high bandwidth communication channel between the GMCH and
the ICH4. The GMCH component provides the processor interface, system memory interface, Hub interface, AGP interface, and an
integrated graphics device with analog and digital display ports. The ICH4 integrates a Universal Serial Bus 2.0 controller, Ultra ATA/100
Controller, Low Pin Count interface, Firmware Hub Flash BIOS interface controller, PCI interface controller, integrated LAN, AC’97 digital
controller, and a Hub Interface for communication with the GMCH.
