2.3 Central Processing Unit (CPU)  
The motherboard comes with a surface mount LGA775 socket designed for  
the Intel® Pentium® 4 processor in the 775-land package.  
Upon purchase of the motherboard, make sure that the PnP cap is  
on the socket and the socket contacts are not bent. Contact your  
retailer immediately if the PnP cap is missing, or if you see any  
damage to the PnP cap/socket contacts/motherboard components.  
ASUS will shoulder the cost of repair only if the damage is shipment/  
transit-related.  
Keep the cap after installing the motherboard. ASUS will process  
Return Merchandise Authorization (RMA) requests only if the  
motherboard comes with the cap on the LGA775 socket.  
The product warranty does not cover damage to the socket  
contacts resulting from incorrect CPU installation/removal, or  
misplacement/loss/incorrect removal of the PnP cap.  
2.3.1 Installing the CPU  
To install a CPU:  
1. Locate the CPU socket on the motherboard.  
®
P5AD2-E Socket 775  
Before installing the CPU, make sure that the cam box is facing towards  
you and the load lever is on your left.

The motherboard supports Intel® Pentium® 4 LGA775 processors with  
the Intel® Enhanced Memory 64 Technology (EM64T), Enhanced Intel  
SpeedStep® Technology (EIST), and Hyper-Threading Technology. Refer  
to the Appendix for more information on these CPU features.

Chapter 2: Hardware information  
2.3.2 Installing the CPU heatsink and fan  
The Intel® Pentium® 4 LGA775 processor requires a specially designed  
heatsink and fan assembly to ensure optimum thermal condition and  
performance.  
When you buy a boxed Intel® Pentium® 4 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® Pentium® 4 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.

2.4 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:  
®
P5AD2-E DDR2 DIMM sockets  
Channel  
Sockets  
Channel A  
Channel B  
DIMM_A1 and DIMM_A2  
DIMM_B1 and DIMM_B2  
2.4.2 Memory configurations  
You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR2  
DIMMs into the DIMM sockets.  
For dual-channel configuration, the total size of memory module(s)  
installed per channel must be the same (DIMM_A1 + DIMM_A2 =  
DIMM_B1 + DIMM_B2).  
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 Qualified Vendors List on  
the next page for details.  
Due to chipset resource allocation, the system may detect less than  
4 GB system memory when you installed four 1 GB DDR2 memory  
modules.  
This motherboard does not support memory modules made up of  
128 Mb chips or double sided x16 memory modules.

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 firmly 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 Configuring an expansion card  
After installing the expansion card, configure the it by adjusting the  
software settings.  
1. Turn on the system and change the necessary BIOS settings, if any.  
See Chapter 3 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,  
conflicts 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.

2.6 Jumpers  
1 . Clear RTC RAM (CLRTC1)  
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!

3.2 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 firmware hub.  
The firmware hub 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 “3.7 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.
