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:
Ensure that all power cables are unplugged before installing the CPU.
• Upon purchase of the motherboard, ensure 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.
1.4.2 Memory congurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered non-ECC DDR2 DIMMs into the
DIMM sockets.
This motherboard supports Intel®Hyper-Threading Technology and Enhanced Intel
SpeedStep®Technology (EIST).
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.
1.6 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.
1.5.1 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.

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.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
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.
• 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.

3. Keyboard/mouse power (3-pin PS2_USBPW1-4)
This jumper allows you to enable or disable the keyboard/mouse and USB port 1-4
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
PS2_USBPW1-4 jumper is for the rear USB ports.

1.7.2 Internal connectors
1. Serial ATA connectors (7-pin SATA1, SATA2)
These connectors are for the Serial ATA signal cables for Serial ATA 3Gb/s hard disk
drives and optical disk drives. The Serial ATA 3Gb/s is backward compatible with the
Serial ATA 1.5Gb/s specication. The data transfer rate of the Serial ATA 3Gb/s is faster
than that of the standard parallel ATA (133Mb/s).
Install the Windows®Service Pack 1 before using Serial ATA.

2. IDE connector (40-1 pin PRI_IDE)
The onboard IDE connector is for the Ultra DMA 133/100/66 signal cable. There are
three connectors on each Ultra DMA 133/100/66 signal cable: blue, black, and gray.
Connect the blue connector to the motherboard’s IDE connector, then select one of the
following modes to congure your device.
Driver Jumper setting Mode of device(s) Cable connector
Single device Cable-Select or Master - Black

Pin 20 on the IDE connector is removed to match the covered hole on the Ultra DMA cable
connector. This prevents incorrect insertion when you connect the IDE cable.
• Use the 80-conductor IDE cable for Ultra DMA 133/100/66 IDE devices.
• If any device jumper is set to Cable-Select, ensure that all other device jumpers have
the same setting.
