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.

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has
a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are
notched differently to prevent installation on a DDR DIMM socket.
The gure illustrates the location of the DDR2 DIMM sockets:
Channel Sockets
Channel A DIMM_A1
Channel B DIMM_B1
1. 7. 2 Me mo ry co nfi gu rat io ns
You may install 256 MB, 512 MB, and 1 GB unbuffered/ECC/non-ECC DDR2
DIMMs into the DIMM sockets.
• You may install varying memory sizes in Channel A and Channel B.
The system maps the total size of the lower-sized channel for the
dual-channel conguration. Any excess memory from the highersized channel is then mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.
• This motherboard does not support memory modules made up of
128 Mb chips or double sided x16 memory modules.

1.8 Expansion slots
In the future, you may need to install expansion cards. The following
sub-sections describe the slots and the expansion cards that they support.
Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage motherboard components.
1. 8. 1 In st all in g a n e xp an s io n c ar d
To install an expansion card:
1. Before installing the expansion card, read the documentation that
came with it and make the necessary hardware settings for the card.
2. Remove the system unit cover (if your motherboard is already
installed in a chassis).
3. Remove the bracket opposite the slot that you intend to use. Keep
the screw for later use.
4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
5. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
1. 8. 2 Co nf igu ri ng an ex pa n si on ca rd
After installing the expansion card, congure it by adjusting the software
settings.
1. Turn on the system and change the necessary BIOS settings, if any.

1. Cl ear RT C R A M ( CLR T C)
This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the
cap on pins 2-3 for about 5~10 seconds, then move the cap back to
pins 1-2.
4. Reinstall the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!
ASUS M 2 N-X 1-19
You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the BIOS
can automatically reset parameter settings to default values.

These connectors are for the Serial ATA signal cables for Serial ATA
3.0 Gb/s hard disk and optical disk drives. The Serial ATA 3 Gb/s is
backward compatible with Serial ATA 1.5Gb/s specication.
The current Serial ATA I interface allows up to 150 MB/s data transfer
rate while Serial ATA II allows up to 300 MB/s data transfer rate,
faster than the standard parallel ATA with 133 MB/s (Ultra DMA133).
If you install Serial ATA hard disk drives, you can create a RAID
0, RAID 1, RAID 0+1, RAID 5, and JBOD conguration through the
onboard NVIDIA® MediaShield™ controller.
Important note on Serial ATA
Install the Windows® 2000 Service Pack 4 or the Windows® XP Service
Pack1 before using Serial ATA.
• For detailed instructions on how to congure RAID 0, 1, 0+1, 5,and
JBOD, refer to the RAID manual in the support CD.
• The RAID function of these connectors is set to [Disabled] by
default. If you intend to create a Serial ATA RAID set using these
connectors, enable the RAID Enabled item in the NVRAID
Conguration sub-menu in the BIOS. See section “2.4.3 Onboard
Device Conguration” for details.

2.2 BIOS setup program
This motherboard supports a programmable rmware chip that you can
update using the provided utility described in section “2.1 Managing and
updating your BIOS.”
Use the BIOS Setup program when you are installing a motherboard,
reconguring your system, or prompted to“Run Setup.” This section
explains how to congure your system using this utility.
Even if you are not prompted to use the Setup program, you can change
the conguration of your computer in the future. For example, you can
enable the security password feature or change the power management
settings. This requires you to recongure your system using the BIOS Setup
program so that the computer can recognize these changes and record
them in the CMOS RAM of the SPI chip.
The rmware chip on the motherboard stores the Setup utility. When you
start up the computer, the system provides you with the opportunity to
run this program. Press <Del> during the Power-On Self-Test (POST) to
enter the Setup utility; otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, reboot the system by doing any of
the following procedures:
• Re s t a rt u s i ng t h e OS s t anda r d shu t - d own p r oce d u r e.
• Pr e s s <C t r l >+< A l t >+<D e l > si m u l tan e o u s ly.
• Pr e s s th e r ese t b utt o n on t h e sys t e m ch a s s is.
• Pr e s s th e p owe r b utt o n to t u r n th e s yst e m off t h en b a c k on .
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys
to force reset from a running operating system can cause damage to
your data or system. We recommend to always shut-down the system
properly from the operating system.
The Setup program is designed to make it as easy to use as possible. Being
a menu-driven program, it lets you scroll through the various sub-menus and
make your selections from the available options using the navigation keys.
• The default BIOS settings for this motherboard apply for most
conditions to ensure optimum performance. If the system becomes
unstable after changing any BIOS settings, load the default settings
to ensure system compatibility and stability. Select the Load Setup
Defaults item under the Exit Menu. See section “2.7 Exit Menu.”
• The BIOS setup screens shown in this section are for reference purposes
only, and may not exactly match what you see on your screen.
• Visit the ASUS website (www.asus.com) to download the latest BIOS
le for this motherboard.
