Operation safety

Before installing the motherboard and adding devices on it, carefully read all the manuals that came with the package. Before using the product, make sure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately. To avoid short circuits, keep paper clips, screws, and staples away from connectors, slots, sockets and circuitry. Avoid dust, humidity, and temperature extremes. Do not place the product in any area where it may become wet. Place the product on a stable surface. If you encounter technical problems with the product, contact a qualified service technician or your retailer.
This symbol of the crossed out wheeled bin indicates that the product (electrical and electronic equipment, Mercury-containing button cell battery) should not be placed in municipal waste. Check local regulations for disposal of electronic products.

1.6.1 Installing the CPU

To install a CPU: 1. Locate the CPU socket on the motherboard.
P5KPL-C/1600 CPU Socket 775
Before installing the CPU, make sure that the cam box is facing towards you and the load lever is on your left.
Press the load lever with your thumb (A), then move it to the left (B) until it is released from the retention tab.

Retention tab Load lever

PnP cap
This side of the socket box should face you.
To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.
Lift the load lever in the direction of the arrow to a 135 angle.
Lift the load plate with your thumb and forefinger to a 100 angle (A), then push the PnP cap from the load plate window to remove (B).

Load plate

Position the CPU over the socket, making sure that the gold triangle is on the bottom-left corner of the socket. The socket alignment key should fit into the CPU notch.

Alignment key

CPU notch

Gold triangle mark

The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU!
Close the load plate (A), then push the load lever (B) until it snaps into the retention tab. If installing a dual-core CPU, connect the chassis fan cable to the chassis fan connector to ensure system stability.
The motherboard supports Intel LGA775 processors with the Intel Enhanced Intel SpeedStep Technology (EIST) and Hyper-Threading Technology. Refer to the Appendix for more information on these CPU features.
Installing 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 Intelcertified multidirectional 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.

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. 1-18 Chapter 1: Product Introduction

The Appendix describes the CPU features and technologies that the motherboard supports.

CPU features

Intel EM64T
The motherboard is fully compatible with Intel LGA775 processors running on 32-bit operating systems. The motherboard comes with a BIOS file that supports EM64T. You can download the latest BIOS file from the ASUS website (www.asus.com/support/download/) if you need to update the BIOS file. See Chapter 2 for details. Visit www.intel.com for more information on the EM64T feature. Visit www.microsoft.com for more information on Windows 64-bit OS.

Using the Intel EM64T feature
To use the Intel EM64T feature: 1. 2. 3. 4. Install an Intel CPU that supports the Intel EM64T. Install a 64-bit operating system (Windows XP Professional x64 Edition, Windows Server 2003 x64 Edition, or Windows Vista x64 Edition). Install the 64-bit drivers for the motherboard components and devices from the support CD. Install the 64-bit drivers for expansion cards or add-on devices, if any.
Refer to the expansion card or add-on device(s) documentation, or visit the related website, to verify if the card/device supports a 64-bit system.
Enhanced Intel SpeedStep Technology (EIST)
The motherboard comes with a BIOS file that supports EIST. You can download the latest BIOS file from the ASUS website (www.asus.com/support/download/) if you need to update the BIOS. See Chapter 2 for details. Visit www.intel.com for more information on the EIST feature.

System requirements

Before using EIST, check your system if it meets the following requirements: Intel Pentium 4 processor or later processor with EIST support BIOS file with EIST support Operating system with EIST support (Windows XP SP2/Windows Server 2003 SP1/Linux 2.6 kernel or later versions)

1. 2. 3. 4. 5. 6. 7.

Using the EIST
To use the EIST feature: Turn on the computer, then enter the BIOS Setup. Go to the Advanced Menu, highlight CPU Configuration, then press <Enter>. Set the Intel SpeedStep Technology item to [Enable], then press <Enter>. Press <F10> to save your changes and exit the BIOS setup. After the computer restarts, right click on a blank space on the desktop, then select Properties from the pop-up menu. When the Display Properties window appears, click the Screen Saver tab.

The screen displays and procedures may vary depending on the operating system.
Intel Hyper-Threading Technology
The motherboard supports Intel Pentium 4 LGA775 processors with Hyper-Threading Technology. Hyper-Threading Technology is supported under Windows XP/2003 Server and Linux 2.4.x (kernel) and later versions only. Under Linux, use the Hyper-Threading compiler to compile the code. If you are using any other operating systems, disable the Hyper-Threading Technology item in the BIOS to ensure system stability and performance. Installing Windows XP Service Pack 1 or later version is recommended. Make sure to enable the Hyper-Threading Technology item in BIOS before installing a supported operating system.
