Introduction
P4SDX socket 478 Pentium 4 motherboard is based on the SiS 655 chipset. Supporting idustry-leading technologies such as dual-channel DDR400, and AGP8X and an abundance of advanced features, the all-new P4SDX enables outstanding performance and value.

Dual-Channel DDR 400
The P4SDX supports dual-channel DDR design up to 6GB high-speed PC3200/PC2700/2100/1600 SDRAM memory for superior performance during the most memory-intensive tasks.

3.06GHz P4 CPU and Intel Hyper-Threading Technology Support
Leveraging the SiS655 chipset to support Intel Hyper-Threading 3.06GHz+ P4 CPUs on 533 MHz FSB, DDR400 memory, the P4SDX delivers a full-value, high-performance solution for today's most demanding tasks.

AGP8X Technology
AGP8X(AGP3.0) is the next generation VGA interface specification that enables enhanced graphics performance with high bandwidth speeds up to 2.12GB/s. With a bus of 533MHz, AGP8X is twice as fast as AGP4X.

Instant Music
No need to boot your computer into the Windows before you can listen to the music, use your desktop system as a CD-Player. You can turn it on and listen to the music within seconds without booting to any operation system.

MyLogo

The P4SDX's S/PDIF out function turns your computer into a high-end entertainment system with digital connectivity to powerful speaker systems.

6 Channel Audio
The P4SDX uses an onboard Audio CODEC that lets you enjoy high-quality 6-channel audio without having to buy advanced sound cards.

10/100 Mbps LAN Support
Easy connectivity to your network or broadband connection with onboard LAN port, lets you take gaming online without having to buy an additional LAN card.

USB 2.0 Ready
USB 2.0 is the latest connectivity standard for next generation components and peripherals. Backward compatible with current USB 1.1 peripherals, USB 2.0 delivers transfer speeds up to 40 times faster at 480Mb/s, for easy connectivity and ultra-fast data

ASUS CrashFree BIOS2
The CrashFree BIOS 2 feature now includes the BIOS auto-recovery function in a support CD.
Users can reboot their system through the support CD when a bootable disk is not available,
and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

C.P.R.(CPU Parameter Recall)
When the system hangs due to overclocking failure, there is no need to open the case to clear CMOS data. Simply restart the system and the BIOS will automatically restore the CPU default setting for each parameter.

ASUS EZ Flash
With ASUS EZ Flash, you can update BIOS before entering operating system. No more DOS-based flash utility and bootable diskette required.

Extreme Overclocking
ASUS P4SDX offers robust overclocking options to maximize your system performance.
- Flexible CPU Core Voltage Adjustments in 0.025V increments over defaults
- SFS (Stepless Frequency Selection) from 100Mhz up to 166MHz at 1MHz increments
- AGP/PCI Asynchronous Mode with FSB (fixed AGP/PCI frequencies)
- ASUS proprietary C.P.R.(CPU Parameter Recall)
