NVIDIA SLI™ Technology
NVIDIA SLI™ (Scalable Link Interface) takes advantage of the increased bandwidth of the PCI Express bus architecture and features intelligent hardware and software that allows two GPUs to efficiently work together to deliver earth-shattering, scalable performance. For some applications nearly 2X performance!

AMD Socket AM2
Supports AMD Socket AM2 Athlon 64 FX / Athlon 64 X2 / Athlon 64 / Sempron
The M2N4-SLI supports AMD socket AM2 single-core Athlon 64/ Sempron and dual-core Athlon 64 X2/ Athlon 64 FX processors with 2MB / 1MB / 512KB L2 cache, which is based on 64-bit architecture. It features 2000 / 1600 MT/s HyperTransport Bus, dual-channel un-buffered DDR2 800 memory support and AMD Cool 'n' Quiet! Technology

Dual-Core CPU
The advanced processing technology contains two physical CPU cores with individually dedicated L2 caches to satisfy the rising demand for more powerful processing capability.

Dual-Channel DDR2 800
DDR2 is the next generation memory technology to replace the current DDR. With the highest speed up to 800MHz, DDR2 memory provides great performance for 3D graphics and other memory demanding applications.

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.

Fanless Design
Provide a cool environment without all the baggage
Cooling fans, though a popular thermal solution, also come with noise and malfunction likelyhood. ASUS Motherboard's fansless concept is specifically created to provide a cool environment without all the baggage.
ASUS has devoted special efforts to address the thermal issues across the motherboard, and most notably the areas that reside the CPU, power, Northbridge and Southbridge.
The heat sinks and strategic board layout are tailor made to dissipate heat in the most efficient manner

ASUS Q-Fan 2
ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan speeds according to system loading to ensure quiet, cool and efficient operation.

Gigbit LAN
The NVIDIA native Gigabit LAN controller delivers transfer speeds up to ten times faster than conventional 10/100 Ethernet connections. Gigabit LAN is the networking standard for the early future and is ideal for handling large amounts of data such as video, audio, and voice.

6 Channel Audio
The M2N4-SLI uses an onboard Audio CODEC that lets you enjoy high-quality 6-channel audio without having to buy advanced sound cards.

Serial ATA 3Gb/s RAID
This motherboard supports next-generation SATA hard drives based on the new SATA 3Gb/s storage specification. The onboard NVIDIA nForce®4 SLI™ MCP allows RAID 0, RAID 1, RAID 0+1, RAID 5 and JBOD configurations for four SATA connectors.

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.

S/PDIF-out on Back I/O Port
This motherboard provides convenient connectivity to external home theater audio systems via an 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.

ASUS Q-Connector
The ASUS Q-Connector allows you to connect or disconnect chassis front panel cables in one easy step with one complete module. This unique adapter eliminates the trouble of plugging in one cable at a time, making connection quick and accurate.

ASUS CrashFree BIOS 3
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a USB flash disk containing the BIOS file. This utility saves users the cost and hassle of buying a replacement BIOS chip.

ASUS EZ Flash 2
EZ Flash 2 is a user-friendly BIOS update utility. Simply press the pre-defined hotkey to launch this tool and update BIOS from a USB flash disk before entering the OS. You can update your BIOS only in a few clicks without preparing an additional floppy diskette or using an OS-based flash utility.

GreenASUS
The motherboard and its packaging comply with the European Union's Restriction on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision of  creating environment-friendly and recyclable products and packaging to safeguard consumers' health while minimizing the impact on the environment.
