Supports AMD Socket 939 Athlon 64FX/Athlon 64
• Supports AMD 939-pin Athlon 64 FX/ Athlon 64 processors with 1MB/512KB L2 cache which is based on 64-bit architecture. It features 2000/1600 MT/s HyperTransport Bus and dual-channel un-buffered DDR400 memory support.

AMD Cool 'n' Quiet! Technology
• Supports AMD Cool 'n' Quiet! Technology, which monitors system operation and automatically adjusts CPU voltage and frequency for a cool and quiet environment.

Dual RAID
• The nFORCE4 chipset incorporated four Serial ATA and two parallel connectors with high performance RAID functions in RAID 0, RAID 1, RAID 0+1 and JBOD. The Silicon Image controller provides another four Serial ATA connectors for RAID 0, RAID 1, RAID1+0, and RAID 5 functions. The A8N-SLI Premium is the ideal solution to enhance hard disk performance and data back up protection without the cost of add-on cards.


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.


Ai Net2
• ASUS AI NET2 remotely detects cable connection the second you turn on the system, and any faulty connections are reported back up to 100 meters at 1 meter accuracy.


AI AUDIO (8-channel digital audio)
• A8N-SLI has eight channels of audio output with Coaxial and optical S/PDIF connector designed to maximize your auditory experience. AI Audio also provides "Jack Sensing" and "UAJ" functions. "Jack Sensing" automatically detects and notifies user of any inappropriate connection. "UAJ" function enables both input and output functions each jacks, thus eliminates the confusion of Line-in, Line-out and Mic jacks once and for all!


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
• ASUS C.P.R.(CPU Parameter Recall)


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


Coaxial/Optical S/PDIF out ports on back I/O
• This motherboard provides convenient connectivity to external home theater audio systems via an optical or coaxial S/PDIF-out (SONY-PHILIPS Digital Interface) jack. It allows to transfer digital audio without converting to analog format and keeps the best signal quality.
