Introduction

Expansion Slots

The system board is equipped with 1 universal AGP slot. AGP is an

interface designed to support high performance 3D graphics cards. It

utilizes a dedicated pipeline to access system memory for texturing,

z-buffering and alpha blending. The universal AGP slot supports AGP

2x with up to 533MB/sec. bandwidth and AGP 4x with up to

1066MB/sec. bandwidth for 3D graphics applications. AGP in this

system board will deliver faster and better graphics to your PC.

The system board is also equipped with 4 dedicated PCI slots, 1

shared PCI/ISA slot and 1 AMR slot. AMR (Audio/Modem Riser) is

an interface designed for installing an audio riser card, modem riser

card or audio/modem riser card that is compliant to the AMR
