1.4Before 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 to 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, and/or components.

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Prescott / Smithfield / Cedarmill / Conroe / Conroe L / Presler / Kentsfield / Yorkfield processor in the 775-land package

•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.

1.6.1Installing the CPU

1.6.2Installing the CPU heatsink and fan

The Intel® Prescott / Smithfield / Cedarmill / Conroe / Conroe L / Presler / Kentsfield / Yorkfield LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.

• When you buy a boxed Intel® Prescott / Smithfield / Cedarmill / Conroe / Conroe L / Presler /Kentsfield / Yorkfield processor, the package

includes the CPU fan and heatsink assembly. If you buy a CPU separately, make sure that you use only Intel® certified multi directional heatsink and fan.

•Your Intel® Prescott / Smithfield / Cedarmill / Conroe / Conroe L / Presler / Kentsfield / Yorkfield LGA775 heatsink and fan assembly comes in a pushpin 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.

Make sure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.

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.

Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan connector.

1.7System memory

1.7.1Overview

The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets.

The figure illustrates the location of the DDR2 DIMM sockets:

A1	DIMM B1
DIMM_

P5KPL-C/1600	112 Pins
	128 Pins

P5KPL-C/1600 240-pin DDR2 DIMM Sockets

Channel	Sockets
Channel A	DIMM_A1
Channel B	DIMM_B1

1.7.2Memory 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. Refer to the DDR2 Qualified Vendors List on the next page for details.

•If you are using a Windows 32-bit version operating system (e.g. 32-bit Windows XP, 32-bit Vista) without the Physical Address Extension (PAE) support, the system will allocate a certain amount of memory space for system devices.

•We recommend that you install only a maximum of 3GB system memory when using a Windows 32-bit version operating system without the PAE.

The excess over 3GB of installed memory will not cause any problem; however, the system can not use this excess memory space and the system will display less than the total size of physical memory installed.
