processor requires a specially designed heatsink and fan assembly to ensure

•

When you buy a boxed Intel® Core™ Quad/ Core™2 Extreme / Core™2
Duo / Pentium® Extreme / Pentium® D / Pentium® 4 / Celeron® E1000
Series and 400 Series CPU, the package includes the CPU fan and
heatsink assembly. If you buy a CPU separately, make sure that you use
only Intel®-certied multi-directional heatsink and fan.

•

Your Intel® Core™ Quad/ Core™2 Extreme / Core™2 Duo / Pentium®
Extreme / Pentium® D / Pentium® 4 / Celeron® E1000 Series and 400
Series 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

1.7.1 Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.

The gure illustrates the location of the DDR2 DIMM sockets:

Channel Sockets

Channel A DIMM_A1 and DIMM_A2

Channel B DIMM_B1 and DIMM_B2

1.7.2 Memory congurations

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
conguration. 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. Refer to the DDR2 Qualied Vendors List on the next page

for details.

• If you are using a Windows 32-bit version operating system (e.g. 32-bit
Windows XP, 32-bit Vista) without the Physical Address Extension (PAE)
support, the system will allocate a certain amount of memory space for
system devices.

• We recommend that you install only a maximum of 3GB system memory
when using a Windows 32-bit version operating system without the PAE.

The excess over 3GB of installed memory will not cause any problem;

however, the system can not use this excess memory space and the

system will display less than the total size of physical memory installed.

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 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.

1.8.2 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 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.

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. Clear RTC RAM (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. 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!

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.

DMA 100/66/33 signal cable has three connectors: a blue connector for the
primary IDE connector on the motherboard, a black connector for an Ultra
DMA 100/66/33 IDE master device (optical drive/hard disk drive), and a gray
connector for an Ultra DMA 100/66/33 IDE slave device (hard disk drive).

If you install two hard disk drives, you must congure the second drive

as a slave device by setting its jumper accordingly. Refer to the hard disk
documentation for the jumper settings.

• Pin 20 on the IDE connector is removed to match the covered hole on the
Ultra DMA cable connector. This prevents incorrect insertion when you
connect the IDE cable.

• Use the 80-conductor IDE cable for Ultra DMA 100/66/33 IDE devices.

4. Serial ATA connectors (7-pin SATA1 [red], SATA2 [black], SATA3 [red],

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, 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

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:

• Restart using the OS standard shut-down procedure.

• Press

• Press the reset button on the system chassis.

• Press the power button to turn the system off then back on.

<Ctrl>+<Alt>+<Del> simultaneously.

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 “2.8 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.
