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 to
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.

1. Place the heatsink on top of the
installed CPU, making sure that
the four fasteners match the
holes on the motherboard.

•

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®-certified mul ti-directional
heatsink and f an.

•

Your Intel® LGA775 processor 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.

Make sure to orient each fastener with the narrow end of the groove
pointing outward. (The photo shows the groove shaded for emphasis.)

Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the
CPU fan connector.

3. Connect the CPU fan cable to the connector on the motherboard
labeled CPU_FAN.

2. Push down two fasteners at
a time in a diagonal sequence
to secure the heatsink and fan
assembly in place.

• Do not forget to connect the CPU fan connector! Hardware
monitoring errors can occur if you fail to plug this connector.

• The retention module of some third-party CPU heatsink and fan
can interfere with chipset components at the bottom of the board.
Before purchasing a separate CPU heatsink and fan, make sure that
it will not interfere with the chipset components.

1.7 System memory

1. 7. 1 Ov er vi ew

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:

Cha nnel Soc kets

Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2

1. 7. 2 Me mo ry c on fi gu ra ti on s

You may install 256 MB, 512 MB, 1 GB, 2 GB and 4 GB unbuffered non-ECC
DDR2 DIMMs into the DIMM sockets.

• For dual-channel conguration, the total size of memory module(s)

installed per channel must be the same
(DIMM_A1 + DIMM_A2 = DIMM_B1 + DIMM_B2).

• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from

the same vendor. Refer to the DDR2 Qualied Vendors List on the next

page for details.

• If you install four 1GB memory modules, the system may only recognize
less than 3 GB because the address space is reserved for other critical
functions. This limitation appears on Windows® XP 32-bit operation
system which does not support Physical Address Extension (PAE).

• If you install Windows

®

XP 32-bit operation system, a total memory of

less than 3GB is recommended.

system components. Failure to do so can cause severe damage to both
the motherboard and the components.

To install a DIMM:

1. Unlock a DIMM socket by
pressing the retaining clips
outward.

2. Align a DIMM on the socket
such that the notch on the
DIMM matches the break on
the socket.

3. Firmly insert the DIMM into
the socket until the retaining
clips snap back in place and
the DIMM is properly seated.

Follow these steps to remove a DIMM.

1. Simultaneously press the retaining
clips outward to unlock the DIMM.

2. Remove the DIMM from the socket.

• A DDR2 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.

• The DDR2 DIMM sockets do not support DDR DIMMs. DO not install
DDR DIMMs to the DDR2 DIMM sockets.

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.

1. 8. 1 In st al li ng a n ex pa ns io n ca rd

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 ig ur in g an e xp an si on c ar d

After installing the expansion card, congure the it by adjusting the

software settings.

1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 2 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.

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.

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.

1.9 Jumpers

1. Cle a r RT C RAM ( 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. Re-install 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!

2.2 BIOS setup program

This motherboard supports a programmable Low-Pin Count (LPC) chip
that you can update using the provided utility described in section “4.1
Managing and updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard,

reconguring your system, or prompted to “Run Setup”. This section
explains how to congure your system using this utility.

Even if you are not prompted to use the Setup program, you can change

the conguration 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 recongure your system using the BIOS Setup

program so that the computer can recognize these changes and record
them in the CMOS RAM of the LPC chip.

The LPC 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, restart the system by pressing
<Ctrl>+<Alt>+<Del>, or by pressing the reset button on the system

chassis. You can also restart by turning the system off and then back on.
Do this last option only if the rst two failed.

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 Default

Settings 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.
