Chapter 1 Product introduction 1.1 Welcome! Thank you for buying an ASUS® P5KPL/EPU motherboard! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
Dual channel DDR2 1066 (O.C.)/800/667 support This motherboard supports DDR2 memory that features data transfer rates of 1066 (O.C.)/ 800/ 667 MHz providing great performance for 3D graphics and other memory-demanding applications. PCI Express architecture PCI Express is the latest I/O interconnect technology that replaces the existing PCI. With a bus bandwidth two times higher than that of AGP 8X interface, PCI Express x16 bus performs much better in applications such as 3D gaming.
ASUS CrashFree BIOS 3 ASUS CrashFree BIOS 3 is an auto-recovery tool that allows you to restore a corrupted BIOS file using the bundled support DVD or USB disk that contains the latest BIOS file. ASUS EZ Flash 2 ASUS EZ Flash 2 is a utility that allows you to update the BIOS without using an OS-based utility. Express Gate Express Gate is an ASUS exclusive OS that provides you with quick access to the Internet and key applications before entering the Windows® OS.
1.4 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.
1.5 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Ensure that you unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components. 1.5.1 Placement direction 1.5.2 Screw holes When installing the motherboard, ensure that you place it into the chassis in the correct orientation.

6. Apply some 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 pre-applied 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. 7.
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.
3. Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN. Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector. 1.6.3 Uninstalling the CPU heatsink and fan To uninstall the CPU heatsink and fan: 1. Disconnect the CPU fan cable from the connector on the motherboard. 2. Rotate each fastener counterclockwise. 3.
4. Carefully remove the heatsink and fan assembly from the motherboard. 5. Rotate each fastener clockwise to ensure correct orientation when reinstalling. 1.7 System memory 1.7.1 Overview The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets.
1.7.2 Memory configurations You may install 512MB, and 1GB unbuffered non‑ECC DDR2 DIMMs into the DIMM sockets. • When using only one DDR2 DIMM, start installing it from DIMM_A1 or DIMM_B1 for better overclocking capability. • For dual-channel configuration (1), install two identical DIMMs in DIMM_A1 and DIMM_B1.

Chassis intrusion connector (4-1 pin CHASSIS) This connector is for a chassis-mounted intrusion detection sensor or switch. Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a high-level signal to this connector when a chassis component is removed or replaced.
5. IDE connector (40-1 pin PRI_EIDE) The onboard IDE connector is for the Ultra DMA 100/66 signal cable. There are three connectors on each Ultra DMA 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 configure your device.
6. • • • • • System panel connector (20-8 pin PANEL) This connector supports several chassis-mounted functions. System power LED (2-pin PLED) This 2-pin connector is for the system power LED. Connect the chassis power LED cable to this connector. The system power LED lights up when you turn on the system power, and blinks when the system is in sleep mode. Hard disk drive activity LED (2-pin IDE_LED) This 2-pin connector is for the HDD Activity LED.
7. USB connectors (10-1 pin USB56, USB78) These connectors are for USB 2.0 ports. Connect the USB module cable to any of these connectors, then install the module to a slot opening at the back of the system chassis. These USB connectors comply with USB 2.0 specification that supports up to 480 Mbps connection speed. Never connect a 1394 cable to the USB connectors.
8. Digital audio connector (4-1 pin SPDIF_OUT) This connector is for an additional Sony/Philips Digital Interface (S/PDIF) port. Connect the S/PDIF Out module cable to this connector, then install the module to a slot opening at the back of the system chassis. The S/PDIF module is purchased separately. 9. Optical drive audio connector (4-pin CD) These connectors allow you to receive stereo audio input from sound sources such as a CD-ROM, TV tuner, or MPEG card.
10. Front panel audio connector (10-1 pin AAFP) This connector is for a chassis-mounted front panel audio I/O module that supports either HD Audio or legacy AC`97 audio standard. Connect one end of the front panel audio I/O module cable to this connector. • We recommend that you connect a high-definition front panel audio module to this connector to avail of the motherboard’s high-definition audio capability.
