savings by detecting current PC loadings and intelligently moderating power  
in real-time. With auto phase switching for components (which includes the  
CPU, VGA card, drives, and system fan), the EPU automatically provides the  
most appropriate power usage via intelligent acceleration and overclocking—  
helping save power and money. See pages 4-21 to 4-24 for details.  
ASUS 3rd Generation 8-Phase Power Design  
The ASUS 3rd Generation 8-Phase Power Design provides highly efficient  
operation to generate less heat (at least 18°C (32.4°F)) than other  
conventional power solutions. It reduces input ripple current and output ripple  
voltage, which keeps CPU and power module from suffering the risk of high  
power stress. It has the advantages of quick transient response and stability,  
especially beneficial when CPU requires more current immediately under  
heavy loading or overclocking mode.  
AI Nap  
With AI Nap, the system can continue running at minimum power and noise  
when you are temporarily away. To wake the system and return to the OS  
environment, simply click the mouse or press a key. See page 4-27 for

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.

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 non-ECC, unbuffered, 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.  
•
•
It is recommended to install the memory modules from the yellow slots for  
better overclocking capability.  
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 1 GB memory modules, the system may only recognize  
less than 3GB because the address space is reserved for other critical  
functions. This limitation appears on Windows® XP/Vista 32-bit operation  
system which does not support Physical Address Extension (PAE).  
•
•
If you install Windows® XP/Vista 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.  
•
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.  
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 vendor-  
marked or at a higher frequency, see section 3.4 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.

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.  
2.5.1  
Installing an expansion card  
To install an expansion card:  
1.  
2.  
3.  
4.  
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 a  
chassis).  
Remove the bracket opposite the slot that you intend to use. Keep the screw  
for later use.

Jumpers  
1.  
Clear RTC RAM (3-pin 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. 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.  
3. Plug the power cord and turn ON the computer.  
4. 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!  
•
•
If the steps above do not help, remove the onboard battery and move  
the jumper again to clear the CMOS RTC RAM data. After the CMOS  
clearance, reinstall the battery.  
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.  
•
Due to the chipset behavior, AC power off is required to enable C.P.R.  
function. You must turn off and on the power supply or unplug and plug the  
power cord before rebooting the system.  
ASUS P5Q WS  
2-19  
 
2.  
CPU / Northbridge overvoltage setting (3-pin OV_CPU; 3-pin OV_NB)  
These jumpers allow you to enable or disable the advanced CPU and  
Northbridge overvoltage settings in BIOS. Read the following information  
before you change the jumper settings. Set to pins 1-2 to activate the  
advanced CPU / Northbridge overvoltage feature.  
OV_CPU  
OV_NB  
Pins 2-3 (Default)  
up to 1.70V  
up to 2.10V  
up to 1.91V  
up to 2.21V  
Pins 1-2 (OV Enabled)  
•
Before you change the jumper settings for extra-high overvoltage ability,  
use the BIOS items introduced in 3.4 Ai Tweaker first to adjust the desired  
CPU and Northbridge performance. Make sure your system function well  
under the highest BIOS voltage settings before you change the setting of  
these two jumpers.  
•
•
Refer to 3.4 Ai Tweaker for more information about CPU and Northbridge  
overvoltage settings.  
DO NOT set the OV_CPU jumper to pins 1-2 when you install a new CPU  
and have not booted for the first time. Doing so may cause the system to  
halt. For system failure due to the wrong setting of the OV_CPU jumper,  
shut down the computer and move the cap back to pins 2-3.  
•
The system may need a better cooling system (for example, a water-cooling  
system) to work stably under high voltage settings.

BIOS setup program  
This motherboard supports a programmable firmware chip that you can update  
using the provided utility described in section 3.1 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 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, 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

RAID configurations  
The motherboard comes with two RAID controllers that allow you to configure  
Serial ATA hard disk drives as RAID sets.  
•
•
Intel® ICH10R Southbridge RAID includes a high performance SATA  
RAID controller that supports RAID 0, RAID 1, RAID 10, and RAID 5 for six  
independent SATA channels.  
Marvell® 6121 RAID includes a high performance SATA RAID controller that  
supports RAID 0 and RAID 1 for two independent eSATA channels.  
4.4.1  
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  
ICH10R 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 4.5  
Creating a RAID driver disk for details.
