P5QL PRO

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 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.

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 should 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.

2.2 Motherboard overview

Before you install the motherboard, study the conguration of your chassis to ensure that the motherboard ts 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.

2.2.1 Placement direction

When installing the motherboard, make sure 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.

2.2.2 Screw holes

Place six (6) 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

ASUS P5QL PRO 2-5

2.3 Central 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 / Celeron® Dual-Core / Celeron® processors.

• Ensure that all power cables are unplugged before installing the CPU.

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

•

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.

2.3.1 Installing the CPU

P5QL PRO

CPU Socket 775

P5QL PRO

To install a CPU:

1. Locate the CPU socket on the motherboard.

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

2. Press the load lever with your thumb (A), then move it to the left (B) until it is released from the retention tab.

To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.

3. Lift the load lever in the direction of

the arrow to a 135º angle.

4. Lift the load plate with your thumb

and forenger to a 100º angle (4A),

then push the PnP cap from the load plate window to remove (4B).

5. Position the CPU over the socket, ensuring that the gold triangle is on the bottom-left corner of the socket

then t the socket alignment key

into the CPU notch.

6. Apply several drops of 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 preapplied 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 nger directly.
