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 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.

2.3.2 Installing the CPU heatsink and fan
®
The Intel
LGA775 processor requires a specially designed heatsink and fan
assembly to ensure optimum thermal condition and performance.
®
•
When you buy a boxed Intel
processor, the package includes the CPU fan
and heatsink assembly. If you buy a CPU separately, make sure that you
®
use only Intel
-certied multi-directional heatsink and fan.
®
• Your Intel
LGA775 heatsink and fan assembly comes in a push-pin design
and requires no tool to install.
• If you purchased a separate CPU heatsink and fan assembly, make sure
that you have properly applied Thermal Interface Material to the CPU
heatsink or CPU before you install the heatsink and fan assembly.
Make sure that you have installed the motherboard to the chassis before you
install the CPU fan and heatsink assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, making sure that
the four fasteners match the holes
on the motherboard.
Orient the heatsink and fan
assembly such that the CPU fan
cable is closest to the CPU fan
connector.

• This chipset ofcially supports DDR2-800 MHz. With the ASUS Super
Memspeed Technology, this motherboard natively supports up to
DDR2-1066 MHz. See the table below.
FSB DDR2
1333 1066*
1333 800
1333 667
1066 1066*
1066 800
1066 667
• *If you install a DDR2-1066 memory module whose SPD is DDR2-800,
make sure that you set the DRAM Frequency item in BIOS to
[DDR2-1066MHz]. See section 4.4.1 Jumperfree Conguration for
details.
2.4.2 Memory congurations
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered non-ECC DDR2
DIMMs into the DIMM sockets.
Recommended Memory Congurations
Sockets
Mode
DIMM_A1 DIMM_B1 DIMM_A2 DIMM_B2
- Populated - -
Single-Channel
Populated - - -
Dual-channel (1) Populated Populated - -
Dual-channel (2) Populated Populated Populated Populated
• 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 higher-sized 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.
• If you install four 1 GB memory modules, the system may only recognize less
than 3GB because the address space is reserved for other critical functions.
®
This limitation appears on Windows
XP/Vista 32-bit operation system which
does not support Physical Address Extension (PAE).
®
• If you install Windows
XP/Vista 32-bit operation system, a total memory of
less than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips.
Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to
8 GB on the operating systems listed below. You may install a maximum of
2 GB DIMMs on each slot.
64-bit
®
Windows
XP Professional x64 Edition
®
Windows
Vista x64 Edition
®
• Some old-version DDR2-800/667 DIMMs may not match Intel
’s
On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR2-533. If this happens, contact your memory vendor to check
the ODT value.

2.5 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.
2.5.1 Installing an expansion card
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.
2.5.2 Conguring an expansion card
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. See
Chapter 4 for information on BIOS setup.
2. Assign an IRQ to the card. Refer to the tables on the next page.
3. Install the software drivers for the expansion card.
When using PCI cards on shared slots, ensure that the drivers support “Share
IRQ” or that the cards do not need IRQ assignments. Otherwise, conicts will
arise between the two PCI groups, making the system unstable and the card
inoperable. Refer to the table on the next page for details.

2.6 Jumper
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. 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!
• 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.
• Due to the chipset limitation, AC power off is required prior using C.P.R.
function. You must turn off and on the power supply or unplug and plug the
power cord before reboot the system.
