Intel 875P chipset
As we discussed earlier, 800MHZ FSB comes as standard if you have a supporting CPU, as does full support for Hyper-Threading, the combination of whiche makes for some incredible performance characteristics.

Dual-Channel DDR400
With increased bandwidths of up to 6.4GB/s the addition of dual channel DDR memory has eliminated a major system bottleneck without the need to purchase costly specialist memory modules. DDR memory is widely, and cheaply available.

Intel PAT
P4C800 Deluxe's built-in Intel PAT (Intel Performance Acceleration Technology) is a trigger for extreme performance. It helps to boost performance by 3~5%.

Multi-RAID for ATA133 & Serial ATA
The P4C800 Deluxe offers the most complete RAID solution. A Promise SATA controller offers RAID 0, 1 and 1+0 functions with Max. 2 UltraATA 133 ports and 2 SATA HD ports, enabling users to build a RAID array with any 2, 3 or 4 of the ports. With unique multi-RAID function, RAID 0 and RAID 1 array can co-exist.

AI NET (Gigabit LAN)
The AI Series supports Gigabit LAN by integrating the 3COM 3C940 controller, equipped with a unique net-diagnosing utility-- VCT (Virtual Cable Tester). The controller intelligently detects net connection status up to 100 meters from a remote location and reports the distance of bad cable.

AI AUDIO (6-channel digital audio)
AI series motherboards employed the world's first intelligent audio CODEC. The 6-channel AD1985 audio CODEC automatically detects and identifies what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection, meaning there will be no more confusion of Line-in, Line-out and Mic jacks.

AI BIOS
CrashFree BIOS 2~
Whenever BIOS gets corrupted, ASUS CrashFree BIOS 2 allows users to reboot the computer and perform an smart auto-recovery procedure through the motherboard support CD.

Q-Fan~
This unique technology intelligently and automatically adjusts CPU fan speeds according to system load and temperature, enabling users to work in a distraction-free environment with minimal noise.

ASUS POST Reporter~
A voice warning design during POST notifies users of any system errors, which means no more complicated LED messages!

AI Overclocking
A unique option in BIOS that enables quick overclocking up to 30% (depends on CPU and RAM). It automatically detects and optimizes every relevant parameter to provide both performance and stability.

The BIOS in AI Series also keeps all the special design for overclocking:
-- Flexible CPU Core Voltage Adjustments in 0.025V increments over defaults
-- SFS (Stepless Frequency Selection) up to 400MHz at 1MHz increanerts
-- Adjustable FSB/DDR ratio. Fixed AGP/PCI frequencies
-- ASUS C.P.R.(CPU Parameter Recall)

AGP8X/Pro
AGP8X (AGP 3.0) is the next generation VGA interface specification that enables enhanced graphics performance with high bandwidth up to 2.12GB/s.

4 Serial ATA ports
Serial ATA is the next generation ATA specification that provides scalable performance for today and tomorrow. With up to 150MB/s data transfer rate, Serial ATA is faster than current Parallel ATA, while providing 100% software compatibility.

IEEE 1394 interface
IEEE 1394 interface provides high speed digital interface for audio / video appliances such as digital television, digital video camcorders, storage peripherals & other PC portable devices.

8 USB 2.0 ports supports
USB 2.0 is the latest connectivity standard for next generation components and peripherals.
Backwards 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 transfers.
