Chapter 1 Introduction

This motherboard has a Socket-478 to support Intel Pentium 4 processors
with Hyper-Threading Technology and Front-Side Bus (FSB) speeds up to
800 MHz(only by overclocking) / 533 MHz. Hyper-Threading Technology,
designed to take advantage of the multitasking features in Windows XP, gives
you the power to do more things at once.
This motherboard integrates the SiS661GX Northbridge and SiS964L
Southbridge that supports the built-in USB 2.0 providing higher bandwidth,
implementing Universal Serial Bus Specification Revision 2.0 and is
compliant with UHCI 1.1 and EHCI 0.95. It supports two DIMM sockets for
DDR400/333/266 up to 2 GB system memory, AC' 97 Audio Codec and Ultra
DMA 133/100/66 function. It has one 8X AGP, one CNR and two 32-bit PCI
slots. There is a full set of I/O ports including two PS/2 ports for mouse and
keyboard, one serial port, one parallel port, one LAN port(optional), one VGA

Supports Intel Pentium 4 Series processors
•
Supports up to 800 MHz(only by overclocking) / 533 MHz Front-Side
•
Bus
Hyper-Threading technology enables the operating system into thinking it's
hooked up to two processors, allowing two threads to be run in parallel, both
on separate 'logical' processors within the same physical processor.
Users please note that this motherboard supports FSB 533 MHz only; FSB
800 MHz can be achieved by overclocking but it may be unstable!
