Supports Intel
®
Socket 478 Pentium
®
4 (Willamette / Northwood) 1.4GHz~2.8GHz+ with 400/533MHz Processor System Bus (PSB)
ed for Socket 478 technology.
The 845GV chipset contains two core components designed for the desktop platform: the 845GV Graphics Memory Controller Hub
nd the Intel I/O Controller Hub 4 (ICH4). These components are interconnected via an Intel proprietary interface called
ace. The Hub Interface is designed into the 845GV chipset to provide an efficient, high bandwidth communication channel
design
Chipset
(GMCH), a
Hub Interf
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.
