CPU Switching Voltage Regulator, System Memory | Microsoft P4X4-ALH

Introduction

CPU Switching Voltage Regulator

The mainboard is equipped with a switching voltage regulator that automati- cally detects a DC power supply from +1.10V to +1.85V.

System Memory

The mainboard uses Double Data Rate Dual Inline Memory Modules (DDR DIMM). Each mainboard has three 184-pin DIMM sockets which support 2.5V (power level) single-sided or double sided PC1600 (DDR200), PC2100 (DDR266) or PC2700 (DDR333) DDR DIMM modules. The maximum memory supported by the mainboard is 3 GB.

Expansion Slots

The mainboard is equipped with six dedicated PCI slots and one 1.5V 4X/8X AGP slot.

Onboard Audio Features

The mainboard supports Microsoft DirectSound/DirectSound 3D and AC97 Full Duplex.

Onboard LAN Features

The mainboard comes with Onboard LAN [VIA VT6103 (PHY)].

WOL (Wake-On-LAN) Port

The mainboard supports Wake-On-LAN functionality.

Word Size
Data Path:	8-bit, 16-bit, 32-bit, 64-bit
Address Path:	32-bit

Front Side Bus Frequency (FSB)

The Front Side Bus Frequency (FSB) clock is 400/533 MHz.

BIOS

•Award BIOS, Windows 95/98 Plug and Play (PnP) compatible

•Supports SCSI sequential boot-up

•2 Mb flash ROM for easy BIOS upgrades

•Supports DMI2.0 function

Desktop Management Interface (DMI)

The mainboard comes with DMI 2.0 built into the BIOS. The DMI utility in the BIOS will automatically record different information about your system configuration and store this information in the DMI pool, which is a part of the system board's Plug and Play BIOS. DMI, along with the appropriately networked software, is designed for easy inventory, maintenance and the simplified troubleshooting of computer systems.
