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.
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. 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.

2.3 Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Extreme / Core™2 Quad / Core™2 Duo / Pentium® Dual-Core / Celeron® Dual-Core / Celeron® processors.
Ensure that all power cables are unplugged before installing the CPU.
If installing a dual-core CPU, connect the chassis fan cable to the CHA_FAN1
connector to ensure system stability.
Due to the chipset limitation, we recommend that you use FSB 800MHz CPU or
above.
Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/ transit-related.
Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA775 socket.
The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.

2.3.1 Installing the CPU

2.4 System memory

2.4.1 Overview

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:
Chapter 2
Recommended memory congurations
One DIMM:
You may install one memory module in any slot as a single-channel operation.
Two DIMMs (dual-channel operation):
Four DIMMs (dual-channel operation):
2-10 Chapter 2: Hardware information
Page 29
2.4.2 Memory congurations
You may install 512MB, 1GB, 2GB and 4GB unbuffered ECC and 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 conguration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
We recommend that you install the memory modules from the yellow slots for better overclocking capability.
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 on the
motherboard.
This motherboard does not support DIMMs made up of 256 megabit (Mb) chips or less.
The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendor-marked or at a higher frequency, see section 3.5 Ai Tweaker menu for manual memory frequency adjustment.
For system stability, use a more efcient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.

2.4.3 Installing a DIMM

Ensure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components.
To install a DIMM:
1. Press the retaining clips outward to unlock a DIMM socket.
2. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket.
Unlocked retaining clip
A DIMM is keyed with a notch so that it ts in only one direction. DO NOT force a DIMM into
a socket to avoid damaging the DIMM.
3. Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.

2.5 Expansion slots

In the future, you may need to install expansion cards. The following subsections describe the slots and the expansion cards that they support.

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).
Chapter 2
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 Conguring an expansion card
After installing the expansion card, congure it by adjusting the software settings.
1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 3 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.
Ensure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conicts 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 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 the CMOS clearance, reinstall the battery.
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 behavior, AC power off is required to enable C.P.R. function. You must turn off and on the power supply or unplug and plug the power cord before rebooting the system.

3. Keyboard/mouse power (3-pin PS2_USBPW56)
This jumper allows you to enable or disable the keyboard/mouse and USB port 5-6 wake-up feature. When you set this jumper to pins 2-3 (+5VSB), you can wake up the computer by pressing a key on the keyboard (the default is the Space Bar), clicking the mouse or using a USB device. This feature requires an ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS. The USBPW56 jumper is for the rear USB ports.
4. USB device wake-up (3-pin USBPW1-4, USBPW7-10, USBPW1112)
Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep modes.
The USBPW1-4 jumper is for the rear USB ports. The USBPW7-10/USBPW1112 jumpers are for the internal USB connectors that you can connect to additional USB ports.
Chapter 2
The USB device wake-up feature requires a power supply that can provide 500mA on
the +5VSB lead for each USB port; otherwise, the system will not power up.
The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.

3.1 Knowing BIOS

BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot device conguration that are needed for system startup in the motherboard CMOS. In normal
circumstances, the default BIOS settings apply to most conditions to ensure optimum performance. We recommend that you not change the default BIOS settings except in the following circumstances:
An error message appears on the screen during the system bootup and requests you to
run the BIOS Setup.
You have installed a new system component that requires further BIOS settings or
update.
Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly
recommend that you change the BIOS settings only with the help of a trained service personnel.

3.2 Updating BIOS

The ASUS website publishes the latest BIOS versions to provide enhancements on system stability, compatibility, or performance. However, BIOS updating is potentially risky.
