Product introduction
Thank you for buying an ASUS® P5KPL-AM IN/GB 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.
• Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, 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.

1.4 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 congurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered non-ECC DDR2 DIMMs into the
DIMM sockets.
1-3 ASUS P5KPL-AM IN/GB
• 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 conguration. 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, 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 do any of the following:
- Install a maximum of 3GB system memory if you are using a 32-bit WindowsInstall a maximum of 3GB system memory if you are using a 32-bit Windows
OS.
- Use a 64-bit WindowsWindows® OS if you want to install 4GB or more memory on the motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
The motherboard supports up to 4GB memory modules on Windows® XP Professional x64
and Vista x64 editions.

1.5 Expansion slots

In the future, you may need to install expansion cards. Refer to the technical documentation that comes with your expansion card for installation details.
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 specications.

1.5.2 PCI Express x16 slot

This motherboard supports a PCI Express x16 graphics card that complies with the PCI Express specications.

1.6 Jumpers

1. USB device wake-up (3-pin USBPW5-8)
Set this jumper 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 this jumper 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 USBPW5-8 jumper is for the internal USB connectors that you can connect to addition USB ports.
• 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 will not power up.
• The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.
1-7 ASUS P5KPL-AM IN/GB
2. 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 the 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 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 clearing the CMOS, 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 so the BIOS can automatically reset parameter settings to default values.

The ASUS CrashFree BIOS 3 is an auto recovery tool that allows you to restore the BIOS le
when it fails or gets corrupted during the updating process. You can update a corrupted BIOS
le using the motherboard Support CD or a USB ash disk that contains the updated BIOS le.
• Prepare the motherboard Support CD or the USB ash disk containing the updated
motherboard BIOS before using this utility.
• Always connect the SATA cable to the SATA1 / SATA2 connector; otherwise, the utility
will not function.
Recovering the BIOS
To recover the BIOS:
1. Turn on the system.
2. Insert the Support CD or the USB ash disk containing the BIOS le to the optical drive
or USB port.
The utility displays the following message and automatically checks the Support CD or
USB ash disk for the BIOS le.
Bad BIOS checksum. Starting BIOS recovery... Checking for CD-ROM...
When the BIOS le is found, the utility reads it and starts erasing the corrupted BIOS le.
Bad BIOS checksum. Starting BIOS recovery... Checking for CD-ROM... CD-ROM found!
Reading le “P5KPLGIN.ROM”. Completed.
