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®‑certified 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 surethat you have properly applied Thermal Interface Material to the CPUheatsink 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 theinstalled CPU, making sure thatthe four fasteners match the holeson the motherboard.
Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the CPU
fan connector.

Overview

The motherboard comes with two 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 notcheddifferently to prevent installation on a DDR DIMM socket.

Memory configurations

You may install 256 MB, 512 MB, 1 GB and 2 GB 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
configuration. Any excess memory from the higher-sized channel is thenmapped 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 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 forsystem device.

•

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

•

This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.

Notes on memory limitations• Due to chipset limitation, this motherboard can only support up to
4 GB on the operating systems listed below. You may install a maximumof 2 GB DIMMs on each slot, but only DDR2-800 and DDR2-667 2 GB 		density modules are available for this configuration.
32-bit		Windows® XP
Windows® 2003 Server
Windows® Vista•

64-bitWindows® XP x64 Edition
Windows® 2003 Server x64 Edition
Windows® Vista x64 Edition

Some old-version DDR2-800 DIMMs may not match Intel®
On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR-667. If this heppens, contact your memory vendor to checkto ODT value.

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.
2.
3.
4.
5.
6.

Before installing the expansion card, read the documentation that came with
it and make the necessary hardware settings for the card.
Remove the system unit cover (if your motherboard is already installed in achassis).

Remove the bracket opposite the slot that you intend to use. Keep the screwfor later use.
Align the card connector with the slot and press firmly until the card iscompletely seated on the slot.
Secure the card to the chassis with the screw you removed earlier.
Replace the system cover.

1.8.2

Configuring an expansion card

After installing the expansion card, configure it by adjusting the software settings.
1.
2.
3.

Turn on the system and change the necessary BIOS settings, if any. See
Chapter 2 for information on BIOS setup.
Assign an IRQ to the card. Refer to the tables on the next page.
Install the software drivers for the expansion card.

When using PCI cards on shared slots, ensure that the drivers support “ShareIRQ” or that the cards do not need IRQ assignments. Otherwise, conflicts willarise between the two PCI groups, making the system unstable and the card

Jumpers

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 •words.
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 tooverclocking. For system failure due to overclocking, use the C.P.R. (CPUParameter 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 thepower cord before reboot the system.

Chapter 2: BIOS setup

2.2

BIOS setup programThis motherboard supports a programmable firmware chip that you can updateusing the provided utility described in section “2.1 Managing and updating your
BIOS.”
Use the BIOS Setup program when you are installing a motherboard, reconfiguring
your system, or prompted to“Run Setup.” This section explains how to configure
your system using this utility.
Even if you are not prompted to use the Setup program, you can change theconfiguration of your computer in the future. For example, you can enable thesecurity password feature or change the power management settings. Thisrequires you to reconfigure your system using the BIOS Setup program so that thecomputer can recognize these changes and record them in the CMOS RAM of the
SPI chip.
The firmware 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 thefollowing procedures:• Restart using the OS standard shut-down procedure.
• Press <Ctrl>+<Alt>+<Del> simultaneously.

• Press the reset button on the system chassis.

• Press the power button to turn the system off then back on.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys toforce reset from a running operating system can cause damage to your dataor system. We recommend to always shut-down the system properly from theoperating system.

The Setup program is designed to make it as easy to use as possible. Being amenu-driven program, it lets you scroll through the various sub-menus and makeyour 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 systemcompatibility 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.
