Product introduction
Thank you for buying an ASUS® P5KPL IN/SI motherboard!
Before you start installing the motherboard, and hardware devices on it, check the items in
your motherboard package. Refer to page ix for the list of accessories.
If any of the items is damaged or missing, contact your retailer.
1.1 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, or components.
Onboard LED
This 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 must 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.

1.2 Motherboard overview
1.2.1 Motherboard layout
Ensure that you install the motherboard into the chassis in the correct orientation. The
edge with external ports goes to the rear part of the chassis.
Place this side towards
the rear of the chassis.
Chapter 1: Product introduction 1-2
Place six screws into the holes indicated by circles to secure the motherboard to the
chassis. DO NOT overtighten the screws! Doing so can damage the motherboard.

DIMM_A1
DIMM_B1
The motherboard comes with a surface mount LGA775 socket for Intel
Core™ 2 Quad / Core™ 2 Duo / Celeron® Processors.
• Ensure that all power cables are unplugged before installing the CPU.
• 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.

Core™ 2 Extreme /
1.4 System memory
1.4.1 Overview
The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory Modules
(DIMM) sockets.
The gure illustrates the location of the DDR2 DIMM sockets:
Channel Sockets
Channel A DIMM_A1
Channel B DIMM_B1
1.4.2 Memory congurations
You may install 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMMs into the DIMM
sockets.
1-3 ASUS P5KPL IN/SI
Page 13
• 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• A lways install DIMMs with the same CAS la tency. For optimum compa tib ility, we
recommend 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.
• The default memory operation frequency depends on its SPD. Under the default state,
some memory modules for overclocking may operate at a lower frequency than the
vendor-marked value.
• For system stability, use a more efcient cooling system to support a full memory load
(2 DIMMs) or overclocking conditions.

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.
1.5.1 PCI slots
The PCI slot supports cards such as LAN cards, SCSI cards, USB cards, and other cards
that comply with the PCI specications.
1.5.2 PCI Express x16 slot
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that
comply with the PCI Express specications.
1.6 Jumpers
1. USB device wake-up (3-pin USBPW1-4, USBPW5-8)
Set this to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM
refreshed, system running in low power mode) using the connected USB devices. Set
to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow
refresh, power supply in reduced power mode).
• The USB device wake-up feature requires a power supply that can provide 500mA on
the +5VSB lead for the USB port. Otherwise, the system would not power up.
• The total current consumed must NOT exceed the power supply capability (+5VSB)
whether under normal condition or in sleep mode.

Normal
(Default)
Clear RTC
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 reenter 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 the parameter settings
to default values.
• 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.

This jumper allows you to enable or disable the keyboard/mouse and USB port 5-6
wake-up feature. When you set this jumper to pins 2-3 (+5VSB), you can wake up the
computer by pressing a key on the keyboard (the default is the Space Bar), clicking
the mouse, or using a USB device. This feature requires an ATX power supply that can
supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS. The
USBPW56 jumper is for the rear USB ports.

connector to avail of the motherboard’s high-denition audio capability.
•
If you want to connect a high-denition front panel audio module to this connector, set
the Front Panel Type item in the BIOS setup to [HD Audio]; if you want to connect an
AC'97 front panel audio module to this connector, set the item to [AC97]. By default, this
connector is set to [HD Audio].

For a fully congured system, we recommend that you use a power supply unit (PSU)
that complies with EATX 12 V Specication 2.0 (or later version) and provides a
minimum power of 400 W.
• Do not forget to connect the 4-pin ATX12V power plug. Otherwise, the system will not
boot.
• We recommended that you use a PSU with a higher power output when conguring a
system with more power-consuming devices. The system may become unstable or may
not boot up if the power is inadequate.

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 that you always shut down the system properly from the operating system.
• The default BIOS settings for this motherboard apply to 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
