Safety information
Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from the
electrical outlet before relocating the system.
• When adding or removing devices to or from the system, ensure that the power
cables for the devices are unplugged before the signal cables are connected. If
possible, disconnect all power cables from the existing system before you add
a device.
• Before connecting or removing signal cables from the motherboard, ensure
that all power cables are unplugged.
• Seek professional assistance before using an adpater or extension cord.
These devices could interrupt the grounding circuit.
• Ensure that your power supply is set to the correct voltage in your area. If you
are not sure about the voltage of the electrical outlet you are using, contact
your local power company.
• If the power supply is broken, do not try to x it by yourself. Contact a qualied
service technician or your retailer.
Operation safety
• Before installing the motherboard and adding devices on it, carefully read all
the manuals that came with the package.
• Before using the product, ensure that all cables are correctly connected and
the power cables are not damaged. If you detect any damage, contact your
dealer immediately.
• To avoid short circuits, keep paper clips, screws, and staples away from
connectors, slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the product in
any area where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact a qualied
service technician or your retailer.
This symbol of the crossed out wheeled bin indicates that the product (electrical

allowing playback of HD DVD, Blu-ray Disc and other protected content.
1.3.2 ASUS Special Features
ASUS Quiet Thermal Solution
ASUS Quiet Thermal solution makes system more stable and enhances the
overclocking capability.
AI Nap
With AI Nap, the system can continue running at minimum power and noise
when you are temporarily away. To wake the system and return to the OS
environment, simply click the mouse or press a key.
Q-Fan 2
ASUS Q-Fan 2 technology intelligently adjusts both CPU fan and chassis fan
speeds according to system loading to ensure quiet, cool and efcient operation.

1-6 Chapter 1: Product Introduction
ASUS EZ DIY
ASUS EZ DIY feature collection provides you easy ways to install computer
components, update the BIOS or back up your favorite settings.
ASUS Q-Connector
ASUS Q-Connector allows you to easily connect or disconnect the chassis
front panel cables to the motherboard. This unique module eliminates the
trouble of connecting the system panel cables one at a time and avoiding
wrong cable connections. See page 1-39 for details.
ASUS CrashFree BIOS 3
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data
from a USB ash disk containing the BIOS le. See page 2-9 for details.
ASUS EZ Flash 2
EZ Flash 2 is a user-friendly BIOS update utility. Simply press the predened
hotkey to launch the utility and update the BIOS without entering the OS.
Update your BIOS easily without preparing a bootable diskette or using an
OS-based ash utility. See page 2-6 for details.
ASUS O.C. Prole
The motherboard features the ASUS O.C. Prole that allows users to
conveniently store or load multiple BIOS settings. The BIOS settings can be
stored in the CMOS or a separate le, giving users freedom to share and
distribute their favorite settings.

ASUS P5N7A-VM 1-7
1.3.4 ASUS Intelligent Overclocking features
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. See page
1-27 for details.
• The actual boot time depends on the system conguration, hardware
conguration, and product model.
• ASUS Express Gate supports le uploading from SATA HDDs, ODDs and
USB drive and downloading to USB drives only.
1.3.3 ASUS Stylish Features
ASUS MyLogo2™
This feature allows you to convert your favorite photo into a 256-color boot logo for
a more colorful and vivid image on your screen. See page 2-34 for details.
AI NET 2
AI NET 2 is a BIOS-based diagnostic tool that detects and reports Ethernet cable
faults and shorts. With this utility, you can easily monitor the condition of the
Ethernet cable(s) connected to the Marvell®LAN (RJ-45) port. During the bootup
process, AI NET 2 immediately diagnoses the LAN cable and reports shorts and
faults up to 100 meters at 1 meter accuracy. See page 2-38 for details.
Express Gate

manager lets you view your pictures without entering Windows at anytime! See
pages 2-38, and 3-10 to 3-18 for details.

1-8 Chapter 1: Product Introduction
1.4 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 that 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.
