This motherboard supports Intel® LGA775 Core™ 2 Extreme / Core™ 2 Quad/ Core™ 2 Duo processors, which are excellent for multitasking, multimedia, and enthusiastic gamers with 1333/ 1066/ 800 MHz FSB.

This motherboard also supports Intel® CPUs in the 45nm manufacturing process.

ASUS P5QL-VM EPU

1-1

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.

Serial ATA 3Gb/s technology

This motherboard supports hard drives based on the Serial ATA (SATA)

3Gb/s storage specifications, delivering enhanced scalability and doubling the bus bandwidth for high-speed data saving and retrieval.

S/PDIF digital sound ready

This motherboard provides convenient connectivity to external home theater audio systems via the S/PDIF-out (SONY-PHILIPS Digital Interface) jack. It allows digital audio transfer and keeps the best signal quality.

Gigabit LAN solution

The onboard LAN controller is a highly integrated Gb LAN controller. It is enhanced with an ACPI management function to provide efficient power management for advanced operating systems.

1.3.2Innovative ASUS features

ASUS MyLogo2™

This feature allows you to convert your favorite photo into a 256-color boot logo for a more colorful and vivid image on your screen.

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.

1-2	Chapter 1: Product introduction

ASUS EZ Flash 2

ASUS EZ Flash 2 is a utility that allows you to update the BIOS without using an OS-based utility.

C.P.R. (CPU Parameter Recall)

The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU parameters to their default settings.

Green ASUS

This motherboard and its packaging comply with the European Union’s Restriction on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision of creating environment-friendly and recyclable products/packaging to safeguard consumers’ health while minimizing the impact on the environment.

ASUS EPU

ASUS EPU detects the current computer loading and intelligently adjusts the appropriate power usage in real-time.

Turbo Key

ASUS Turbo Key allows you to turn the PC power button into an overclocking button. After you easy setup, Turbo Key boosts

performances without interrupting ongoing work or games, simply through pressing the button.

ASUS AI NET2

ASUS AI NET2 remotely detects the cable connection immediately after turning on the system, and any faulty cable connections are reported back up to 100 meters at 1 meter accuracy.

ASUS P5QL-VM EPU

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.

•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

The 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.

Chapter 1: Product introduction

1.5Motherboard 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.

1.5.1Placement direction

When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below.

1.5.2Screw holes

Place six screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not overtighten the screws! Doing so can damage the motherboard.

Place this side towards the rear of the chassis

1.6Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Extreme / Core™2 Quad / Core™2 Duo / Pentium® Dual-Core processors.

• Unplug all power cables before installing the CPU.

•Connect the chassis fan cable to the CHA_FAN connector to ensure system stability.

•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.

The motherboard supports Intel® LGA775 processors with the Intel® Enhanced Intel SpeedStep® Technology (EIST) and Hyper-Threading Technology.

1.6.1Installing the CPU

To install a CPU:

1.Locate the CPU socket on the motherboard.

Before installing the CPU, ensure that the cam box is facing towards you and the load lever is on your left.

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.Close the load plate (A), then push

the load lever (B) until it snaps into the	A
retention tab.

1.6.2Installing 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.

•If you purchased a separate CPU heatsink and fan assembly, ensure that you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan assembly.

Ensure 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:		A
	1.	Place the heatsink on top of the installed
			B
		CPU, ensuring that the four fasteners match
			B
		the holes on the motherboard.
		Orient the heatsink and fan assembly	A
		such that the CPU fan cable is closest to
		the CPU fan connector.

2.Push down two fasteners at a time in a

diagonal sequence to secure the heatsink
and fan assembly in place.		1
