Chapter 1: Product introduction
DDR2 memory support
The motherboard supports DDR2 memory that features data transfer rates of
667 MHz or 533 MHz to meet the higher bandwidth requirements of the
latest 3D graphics, multimedia, and Internet applications. The dual-channel
DDR2 architecture doubles the bandwidth of your system memory to boost
system performance, eliminating bottlenecks with peak bandwidths of up to
10.7 GB/s. See pages 2-10 to 2-14 for details.
Dual RAID solution
Onboard RAID controllers provide the motherboard with dual-RAID
functionality that allows you to select the best RAID solution using Serial
ATA devices.
The Intel® ICH7-M (DH) Southbridge allows RAID 0, RAID 1, and Intel® Matrix
Storage configuration with two Serial ATA connectors. See pages 2-27 and
5-28.
The Jmicron® JMB363 Serial ATA controller supports one internal and one
external Serial ATA 3.0 Gb/s devices with RAID 0 and RAID 1 configuration.
See pages 2-28 and 5-36 for details.
Gigabit LAN solution
The motherboard comes with the Intel® 82573L Gigabit LAN controller to
provide the total solution for your networking needs. This network
controller uses the PCI Express segment to provide faster data bandwidth
for your wired or wireless Internet, LAN, and file sharing requirements. See
page 2-24 for details.
PCI Express™ interface
The motherboard fully supports PCI Express, the latest I/O interconnect
technology that speeds up the PCI bus. PCI Express features point-to-point
serial interconnections between devices and allows higher clockspeeds by
carrying data in packets. This high speed interface is software compatible with
existing PCI specifications. See page 2-18 for details.
S/PDIF digital sound ready
The motherboard supports the S/PDIF technology through the S/PDIF
interfaces on the rear panel and at midboard. The S/PDIF technology turns
your computer into a high-end entertainment system with digital connectivity
to powerful audio and speaker systems. See page 2-35 for details.
ASUS N4L-VM DH
1-3
8-channel High Definition Audio
Onboard is the Realtek® ALC882M High Definition Audio 8-channel audio
CODEC. This CODEC is fully-compliant with Intel® High Definition Audio
standard (192 KHz, 24-bit audio). With the CODEC, audio ports, and S/PDIF
interfaces, you can connect your computer to home theater decoders to
produce crystal-clear digital audio.
The Realtek® ALC882M CODEC comes with an AC-3 encoder capable of
transforming your computer’s digital audio contents into real-time Dolby®
Digital stream. This digital stream passes through the S/PDIF out interfaces
to an AC-3 decoder for 7.1-channel feedback.
The Realtek® ALC882M CODEC comes with a software application that
features jack detection to monitor the plugging status of each jack,
impedance sensing to determine audio device classes, and pre-defined
equalization for various audio devices. See pages 2-24, 2-25, and 5-11 for
details.
Theater-level audio
(designed for Dolby® Master Studio
This motherboard offers theater-level 7.1 surround sound and audio
specifications higher than that of DVD. Enjoy true home theater experience
with the following advanced sound technologies: Dolby IIX, Dolby
Headphone, Dolby Virtual Speaker, and Dolby Digital Live. See page 5-16
for details.
IEEE 1394a support
The IEEE 1394a interface provides high-speed and flexible PC connectivity
to a wide range of peripherals and devices compliant to the IEEE 1394a
standard. The IEEE 1394a interface allows up to 400 Mbps transfer rates
through simple, low-cost, high-bandwidth asynchronous (real-time) data
interfacing between computers, peripherals, and consumer electronic
devices such as camcorders, VCRs, printers, TVs, and digital cameras. See
page 2-24 for details.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0
specification, dramatically increasing the connection speed from the
12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is
backward compatible with USB 1.1. See pages 2-25 and 2-29 for details.

Chapter 1: Product introduction
1.3.2 ASUS Special features
Serial ATA II and SATA-On-The-Go
The motherboard supports the Serial ATA II 3 Gb/s technology through the
JMicron Serial ATA interfaces. The Serial ATA 3 Gb/s specification provides
twice the bandwidth of the current Serial ATA products with a host of new
features, including Native Command Queuing (NCQ), Power Management
(PM) Implementation Algorithm, and Hot Swap. Serial ATA allows thinner,
more flexible cables with lower pin count and reduced voltage requirements.
Leveraging these Serial ATA II 3Gb/s features is the SATA-On-The-Go. This
external port on the rear panel I/O provides smart setup, hot-plug and
support for up to 16 devices with port-multiplier functions. See pages 2-25
and 2-26 for details.
ASUS Q-Fan technology
The ASUS Q-Fan technology smartly adjusts the CPU fan speeds according
to the system loading to ensure quiet, cool, and efficient operation. See
page 4-32 for details.
ASUS MyLogo™
This feature allows you to personalize and add style to your system with
customizable boot logos. See page 5-9 for details.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to
the BIOS default settings in case the system hangs due to overclocking.
When the system hangs due to overclocking, C.P.R. eliminates the need to
open the system chassis and clear the RTC data. Simply shut down and
reboot the system, and the BIOS automatically restores the CPU default
setting for each parameter.

2.1 Before you proceed
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
•
•
Unplug the power cord from the wall socket before touching any
component.
Use a grounded wrist strap or touch a safely grounded object or
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
•
•
Hold components by the edges to avoid touching the ICs on them.
Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
•
Before you install or remove any component, ensure
that the ATX power supply is switched off or the
power cord is detached from the power supply. Failure
to do so may cause severe damage to the motherboard, peripherals,
and/or components.
Onboard LED
The motherboard comes with a standby power LED. The green LED
lights up to indicate that the system is ON, in sleep mode, or in
soft-off mode. This is a reminder that you should shut down the
system and unplug the power cable before removing or plugging in
any motherboard component. The illustration below shows the
location of the onboard LED.

2.2 Motherboard overview
Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and damage
motherboard components.
2.2.1 Placement direction
When installing the motherboard, make sure that you place it into the
chassis in the correct orientation. The edge with external ports goes to the
rear part of the chassis as indicated in the image below.
2.2.2 Screw holes
Place eight (8) screws into the holes indicated by circles to secure the
motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards
the rear of the chassis
