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 845GE/PE chipset contains two core components designed for the desktop platform: the 845GE/PE 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 845GE/PE 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 (845GE only). 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.
Expansion Slots
Including three 32-bit/33MHz PCI, one AGP 4X slots. The
PCI
local bus throughput can be up to 132MB/s. The
Accelerated Graphics Port
(AGP)
specification provides a new level of video display sophistication and speed. The AGP video cards support data transfer rate up to
1056MB/s. AX4GE Tube / AX4PE Tube motherboard includes one AGP expansion slot for a bus mastering AGP graphic card. For AD and
SBA signaling, AX4GE Tube / AX4PE Tube motherboard can support 4X mode.
Of three PCI slots provided, all of them are master PCI
slots with arbitration and decoding for all integrated functions and LPC bus.
