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.

Apply several drops of Thermal Interface
Material to the exposed area of the CPU
that the heatsink will be in contact with,
ensuring that it is spread in an even thin
layer.
Some heatsinks come with preapplied thermal paste. If so, skip this
step.
DO NOT eat the Thermal Interface Material. If it gets into your eyes or touches your skin,
ensure that you wash it off immediately, and seek professional medical help.
To prevent contaminating the paste, DO NOT spread the paste with your finger directly.

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, ensure 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.
Ensure that you have installed the motherboard to the chassis before you install the CPU
fan and heatsink assembly.
A
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.
2.
Push down two fasteners at a time in a
diagonal sequence to secure the heatsink
and fan assembly in place.

• When using only one memory module, start installing the DDR2 DIMM from slot
DIMM_A1 or DIMM_B1 for better overclocking capability.
• For dual-channel configuration, you may:
-
-
install identical DIMMs in all four sockets OR
install identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow sockets) and another identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)
• Always use identical DDR2 DIMM pairs for dual channel mode. For optimum
compatibility, we recommend that you obtain memory modules from the same vendor.
1.7.2
Memory configurations
You may install 256MB, 512MB, 1GB and 2GB 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.
• Due to the memory address limitation on 32-bit Windows OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you install a 64-bit
Windows OS when having 4GB or more memory installed on the motherboard.
• Due to chipset limitation, this motherboard only supports up to the total of four ranks (four
sides in total) of RAM at max.
• This motherboard does not support DIMMs made up of 256 megabit (Mb) chips or less.

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.
Ensure 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.
Before installing the expansion card, read the documentation that 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.
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.
Assign an IRQ to the card.
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.
1.8.4
PCI slots
1.8.5

Jumper
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 CPU Parameter Recall (C.P.R.) feature. Shut
down and reboot the system, then the BIOS automatically resets parameter settings to
default values.
P5QL-EM
• Due to the chipset limitation, AC power off is required before you use the C.P.R.
function. You must turn off and on the power supply or unplug and plug the power cord
before rebooting the system.

2.2
BIOS setup program
This motherboard supports a programmable Serial Peripheral Interface (SPI) 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 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, 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 power button to turn the system off then back on.
•
Press the reset button on the system chassis.
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 Setups Default 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.
• Visit the ASUS website at www.asus.com to download the latest BIOS file for this
motherboard.
