1-3  
Fanless Design - Heat-pipe  
The Heat Pipe design effectively directs the heat generated by the chipsets to  
the heatsink near the back IO ports, where it can be carried away by existing  
airflow from CPU fan or bundled optional fan. The purpose of the innovative  
heat pipe design on this motherboard is that the groundbreaking fanless  
design does not have lifetime problems as a chipset fan does. Furthermore, it  
provides options for users to install side-flow fan or passive cooler. The Heat  
Pipe design is the most reliable fanless thermal solution to date.  
Q-Fan 2  
ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan  
speeds according to system loading to ensure quiet, cool and efficient operation.  
See pages 4-30 and 5-26 for details.  
ASUS Crystal Sound  
This feature can enhance speech-centric applications like Skype, online game,  
video conference and recording.  
Noise Filter  
This feature detects repetitive and stationary noises (non-voice signals) like  
computer fans, air conditioners, and other background noises then eliminates  
it in the incoming audio stream while recording. See page 5-28 for details.  
ASUS EZ DIY  
ASUS EZ DIY feature collection provides you easy ways to install computer  
components, update the BIOS or back up your favorite settings.  
ASUS Q-Connector  
ASUS Q-Connector allows you to easily connect or disconnect the chassis  
front panel cables to the motherboard. This unique module eliminates the  
trouble of connecting the system panel cables one at a time and avoiding  
wrong cable connections. See page 2-34 for details.

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 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.  
Onboard LED  
The motherboard comes with a standby power LED that 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.

2.3.2  
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, 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 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  
installed CPU, making sure that  
the four fasteners match the holes  
on the motherboard.  
Orient the heatsink and fan  
assembly such that the CPU fan  
cable is closest to the CPU fan  
connector.

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 figure illustrates the location of the DDR2 DIMM sockets:

2.4.2  
Memory configurations  
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC / 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 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.  
If you install four 2GB memory modules, the system may only recognize less  
than 8GB 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.  
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  
8 GB on the operating systems listed below. You may install a maximum of  
2 GB DIMMs on each slot, but only DDR2-533 and DDR2-667 2 GB density  
modules are available for this configuration.  
32-bit  
64-bit  
Windows® 2000 Advanced Server  
Windows® XP Professional x64 Edition  
Some old-version DDR2-800/667 DIMMs may not match Intel®’s  
On-Die-Termination (ODT) requirement and will automatically downgrade  
to run at DDR2-533. 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.  
Due to chipset limitation, DDR2-667 with CL=3 will be downgraded to run  
at DDR2-533 by default setting. If you want to operate with lower latency,  
adjust the memory timing manually.

Jumper  
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. 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.

ASUS CrashFree BIOS 3 utility  
The ASUS CrashFree BIOS 3 is an auto recovery tool that allows you to restore  
the BIOS file when it fails or gets corrupted during the updating process. You can  
update a corrupted BIOS file using the motherboard support DVD, the floppy disk,  
or the USB flash disk that contains the updated BIOS file.  
Prepare the motherboard support DVD, the floppy disk or the USB flash disk  
containing the updated motherboard BIOS before using this utility.  
Recovering the BIOS from the support DVD  
To recover the BIOS from the support DVD:  
1.  
2.  
3.  
Turn on the system.  
Insert the motherboard support DVD to the optical drive.  
The utility displays the following message and automatically checks the DVD  
for the BIOS file.  
Bad BIOS checksum. Starting BIOS recovery...  
Checking for floppy...  
When found, the utility reads the BIOS file and starts flashing the corrupted  
BIOS file.  
Bad BIOS checksum. Starting BIOS recovery...  
Checking for floppy...  
Floppy found!  
Reading file “P5K-WS.ROM”. Completed.  
Start flashing...  
4.

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, 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 the  
configuration 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 reconfigure 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, restart the system by pressing  
<Ctrl+Alt+Delete>, 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 first 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 4.8 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.  
Visit the ASUS website (www.asus.com) to download the latest BIOS file for  
this motherboard.

Marvell® 88SE6121 RAID. Enabled by Marvell® 88SE6121 controller,  
Marvell® RAID extends the advantages of software RAID beyond internal hard  
disk drives to an external disk or external, port-multiplier enabled enclosure  
5.4.1  
RAID definitions  
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write  
data in parallel, interleaved stacks. Two hard disks perform the same work as a  
single drive but at a sustained data transfer rate, double that of a single disk alone,  
thus improving data access and storage. Use of two new identical hard disk drives  
is required for this setup.  
RAID 1 (Data mirroring) copies and maintains an identical image of data from  
one drive to a second drive. If one drive fails, the disk array management software  
directs all applications to the surviving drive as it contains a complete copy of  
the data in the other drive. This RAID configuration provides data protection and  
increases fault tolerance to the entire system. Use two new drives or use an  
existing drive and a new drive for this setup. The new drive must be of the same  
size or larger than the existing drive.  
RAID 5 stripes both data and parity information across three or more hard  
disk drives. Among the advantages of RAID 5 configuration include better  
HDD performance, fault tolerance, and higher storage capacity. The RAID  
5 configuration is best suited for transaction processing, relational database  
applications, enterprise resource planning, and other business systems. Use a  
minimum of three identical hard disk drives for this setup.  
RAID 10 is data striping and data mirroring combined without parity (redundancy  
data) having to be calculated and written. With the RAID 10* configuration you get  
all the benefits of both RAID 0 and RAID 1 configurations. Use four new hard disk  
drives or use an existing drive and three new drives for this setup.  
Intel® Matrix Storage. The Intel® Matrix Storage technology supported by the  
ICH9R chip allows you to create a RAID 0, RAID 1, RAID 5, and RAID 10* function  
to improve both system performance and data safety. You can also combine two  
RAID sets to get higher performance, capacity, or fault tolerance provided by the  
difference RAID function. For example, RAID 0 and RAID 1 set can be created by  
using only two identical hard disk drives.  
If you want to boot the system from a hard disk drive included in a created RAID  
set, copy first the RAID driver from the support DVD to a floppy disk before you  
install an operating system to the selected hard disk drive. Refer to section “5.5  
Creating a RAID driver disk” for details.
