Chapter 1
Product introduction
Thank you for buying an ASUS® AT3N7A-I motherboard!
Before you start installing the motherboard, and hardware devices on it, check the items in
your motherboard package. Refer to page ix for the list of accessories.
If any of the items is damaged or missing, contact your retailer.
1.1
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.
Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, 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, 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 must 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.

1.4.2
Memory configurations
You may install 512MB, 1GB, and 2GB unbuffered 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 configuration. Any excess
memory from the higher-sized channel is then mapped for the 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.
Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:
-
-
Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
Install a 64-bit Windows® OS when you want to install 4GB or more memory on
the motherboard.
•
This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
This motherboard supports up to 4GB on Windows® XP Professional x64 and Windows®
Vista x64 editions. You may install a maximum of 2GB DIMMs on each slot.

Jumpers
1.
Clear RTC RAM (3-pin CLRTC)
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. 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.
3. Plug the power cord and turn ON the computer.
4. 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!
If the steps above do not help, remove the onboard battery and move the jumper again to
clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
