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.

1.6.2  
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  
1.7.1  
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 notched  
differently to prevent installation on a DDR DIMM socket.  
The figure illustrates the location of the DDR2 DIMM sockets:

Channel A  
Channel B

Install a memory module in DIMM_A1 slot to support the Intel® Quiet System  
Technology and for optimum performance.

Chapter 1: Product introduction  
1.7.2  
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 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 two 2GB 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 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  
4 GB on the operating systems listed below. You may install a maximum  
of 2 GB DIMMs on each slot, but only DDR2-800 and DDR2-667 2 GB  
density modules are available for this configuration.  
32-bit  
64-bit  
Windows® XP  
Windows® 2003 Server  
Windows® Vista  
Windows® 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 check  
to ODT value.

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.  
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.  
Align the card connector with the slot and press firmly until the card is  
completely seated on the slot.  
5.  
6.  
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.  
Turn on the system and change the necessary BIOS settings, if any. See  
Chapter 2 for information on BIOS setup.  
2.  
3.  
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 “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.

Jumpers  
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 •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!

Normal  
(Default)  
Clear RTC  
P5KPL-VM Clear RTC RAM  
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 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 the  
power cord before reboot the system.

BIOS setup program  
This motherboard supports a programmable firmware chip that you can update  
using 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 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, reboot the system by doing any of the  
following 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 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 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.
