* Supports AMD Socket 939 Athlon 64FX/Athlon 64

A8N-SLI 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.
* NVIDIA nForce4 Ultra

NVIDIA nForce4 Ultra deliver unmatched PC security and unbelievable PC 

performance. Get it all: PCI Express for AMD platforms and cutting-edge 

features including SATA 3Gb/s and NVIDIA nForce Security -- protection 

from spyware and hackers. NVIDIA nForce4 Ultra ensure maximum PC 

performance while futureproofing your PC for demands of tomorrow. 
* PCI Express Architecture

PCI Express is the latest I/O interconnect technology that will replace 

the existing PCI. With a bus bandwidth 4 times higher than that of AGP 

8X interface, PCI Express x16 bus performs much better in applications 

such as 3D gaming. The PCI Express x1 interface creates new usages on 

desktop PCs e.g., TV tuner, 1394b, and high-speed RAID systems.
* SATA 3Gb/s

A8N-SLI supports next-generation SATA hard drives based on the new SATA 

3Gb/s storage specification. Furthermore, the chipset has two dedicated 

SATA controllers delivering more scalable performance and doubles the 

bus bandwidth for fast hard drive data retrieval and saves.
* NV 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. 
* Precision Tweaker

Precision Tweaker is designed for serious overclockers. It offers ways 

to raise system performance inch-by-inch and step-by-step to achieve 

maximum performance! This is about getting the most out of your machine, 

and taking pride in your customized computer. Precision Tweaker provides 

overclocking options for all major parts of the system: CPU, Memory, 

PCI-Express, and Front Side Bus.

- vDIMM 

Take control of how much power is going into the memory modules. ASUS 

gives you 9-step voltage control to the DIMM.

- vCore 

Find out "exactly" how much power your CPU needs. Fine-tune it with 

0.0125 volts at a time!

- PCI-Express Frequency 

Explore the frequency options of your PCI-Express graphics card.

- SFS

SFS (Stepless Frequency Selection) allow FSB tuning from 200MHz up to 

400MHz at 1MHz increments.
* AI NOS

Applications such as 3D games and video editing demand a huge chunk of 

system resource.
Inject "nitrous oxide" into your CPU! The patented AI 

NOS (Non-delay Overclocking System) technology intelligently detects 

system load and automatically boosts performance for the most demanding 

tasks. Unlike other dynamic overclocking techniques, AI NOS reacts much 

faster to satisfy your unending need for speeds.
* PEG Link 

PEG (PCI-Express Graphics) Link lets you to raise GPU and VGA memory 

throughput via the motherboard BIOS the same way system bus and memory 

bus are tweaked. ASUS engineers carefully fine-tuned the parameters for 

PCI-Express cards to provide system stability during high-speed graphics 

operation. Furthermore, with two PCI-Express slots, the A8N-E is able to 

activate PEG Link on both graphics.
* AI NET2

Diagnose LAN connection before entering OS! Network problems are often 

caused by bad cable connection. 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. 
* NV Firewall

NV ActiveArmor enhances network security while delivers the highest 

system performance by offloading CPU-intensive packet filtering tasks in 

hardware. NV Firewall provides professional-grade traffic inspection 

capabilities, instanton protection, advanced management features and is 

easy to use and setup via a user friendly wizard. 
* AI Audio (8-channel 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! 
* ASUS Q-Fan

ASUS Q-Fan technology intelligently adjusts both CPU fan and chassis fan 

speeds according to system loading to ensure quiet, cool and efficient 

operation. 
* Universal PCI-E Slot 

The ASUS Universal PCI-E Slot gives the users freedom and flexibility on 

the utilization of the PCI-E interface. With Universal PCI-E Slot, user 

is able to plug in an additional PCI-E graphics card to have dual VGA on 

a single motherboard! This special design supports up to 1GB/s in 

bandwidth, and it will also take in most of the PCI-E devices out there!
* Max. 10 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. 
* Multi-language BIOS

The multi-language BIOS allows you to select the language of your choice 

from the available options. The localized BIOS setup menu helps you 

configure your system easier and faster.
* ASUS CrashFree BIOS2

The CrashFree BIOS2 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. 
* S/PDIF-out on Back I/O Port

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.
