This Athlon 64, nForce 3 motherboard distinguished itself from other solutions of the same platform by adopting the best features to date. Just name it: 8-channel audio, 6 Serial ATA, intelligent features for BIOS and audio setup, and a full lineup of unique and innovative designs.


64bit CPU support
64-bit computing, the next generation technology to replace current 32-bit architecture, delivers advanced system performance, faster memory access and increased productivity. This motherboard provides excellent compatibility and flexibility by supporting either 64-bit or 32-bit architecture.

AMD Athlon 64 Processor
The AMD Athlon 64 processor is based on AMD64 technology, which represents the landmark introduction of the industry's first x86-64 technology. This next-generation processor provides a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership and development. AMD Cool 'n' Quiet™technology enables processor frequency and voltage switching to reduce power and fan speed."


6 Serial ATA ports
K8N-E Deluxe integrates 6 Serial ATA ports for your storage needs. 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.

Dual RAID
The nForce3 250Gb chipset incorporated two Serial ATA and two parallel connectors with RAID 0, RAID 1, RAID 10 and JBOD functions while the Silicon Image controller provides another four Serial ATA connectors for RAID 0, RAID 1, RAID 10, RAID 5, and JBOD functions. The K8N-E Deluxe is the ideal solution to enhance hard disk performance and data back up protection without the cost of add-on cards.

NV Firewall
NV Firewall is a high-performance, network-level firewall integrated into K8N. It has professional grade traffic inspection capabilities and advanced management features. In addition, NV Firewall also has unique anti-hacking features not found in other PC firewalls! Because it's native, NV Firewall eliminates interoperability issues, improves throughput and protection, with no extra cost to your pocket or CPU resources!

AI Audio (8-channel Audio)
The ALC850 has eight channels of 16-Bit DAC, a stereo 16-Bit ADC, and an AC97 2.3 compatible multi-channel audio designed for PC multimedia systems. The CODEC can also automatically detect and identify what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection. No more confusion of Line-in, Line-out and Mic jacks.

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.

ASUS AI BIOS
CrashFree BIOS2
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 2
A voice warning design during POST notifies users of any system errors, which means no more complicated LED messages!

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

AI Overclocking
ASUS K8N-E Deluxe offers robust overclocking options to maximize your system performance.
-- SFS (Stepless Frequency Selection) from 200MHz up to 300MHz at 1MHz increment
-- CPU, Memory and AGP voltage adjustable
-- ASUS C.P.R. (CPU Parameter Recall)

ASUS MyLogo2
You can convert your favorite photo into a 256-color boot logo for a more colorful and vivid image on your screen.

Multi-language BIOS
ASUS provides friendly localized BIOS setup menu to help you configure your system as easy as possible.

Instant music
Through this unique feature, K8N-E Deluxe is conveniently designed to allow users to enjoy their favorite music without the need to enter Windows.

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.

C.P.R.(CPU Parameter Recall)
When the system hangs due to overclocking failure, there is no need to open the case to clear the CMOS data. Just simply restart the system, the BIOS would show the previous setting and then users can amend the CPU setting again.

8 USB 2.0 ports support
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 transfers
