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, ensure that you use
only Intel®-certied multi-directional heatsink and fan.

®

• Your Intel
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.

Ensure that you have installed the motherboard to the chassis before you install
the CPU fan and heatsink assembly.

LGA775 heatsink and fan assembly comes in a push-pin design

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.

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

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.

®

• When you install a total memory of 4GB or more, Windows

32-bit

operation system may only recognize less than 3GB. Hence, a total

installed memory of less than 3GB is recommended if you are using a
Windows 32-bit operation system.

• This motherboard does not support memory modules made up of 128 Mb
chips.

This motherboard can support up to 16GB on the operating systems listed
below. You may install a maximum of 4GB DIMMs on each slot.

64-bit

Windows® XP Professional x64 Edition

Windows® Vista x64 Edition

• The default memory operation frequency is dependent on its SPD. Under
the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value. To operate at the vendor­marked or at a higher frequency, see section 4.4 Ai Tweaker menu for
manual memory frequency adjustment.

• The memory modules may require a better cooling system to work stably
under full loading (4 DIMMs) or overclocking setting.

®

• Some old-version DDR2-800 DIMMs may not match Intel

’s

On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR2-667. If this happens, contact your memory vendor to check
the ODT value.

• Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run
at DDR2-667 by default setting. If you want to operate with lower latency,
adjust the memory timing manually.

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.

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.

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 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 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, 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.

4.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) 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

SPI chip.

The SPI 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 Setups Default item under the
Exit Menu. See section 4.9 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.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for

this motherboard.
