2.1 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.
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.

2.2.3 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.

2.2.4 Screw holes

Place eight (8) 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
2-4 Chapter 2: Hardware information

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.
Make sure that all power cables are unplugged before installing the CPU.
If installing a dual-core CPU, connect the chassis fan cable to the CHA_FAN1 connector to ensure system stability.
Due to the chipset limitation, we recommend you use FSB 800MHz CPU or
above.
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.
ASUS P5N-VM WS 2-5

2.3.1 Installing the CPU

To install a CPU:
1. Locate the CPU socket on the motherboard.
Before installing the CPU, make sure 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).

orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU!
6. Apply several drops of thermal paste 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.

The Thermal Interface Material is toxic and inedible. If it gets into your eyes or touches your skin, ensure to wash it off immediately, and seek professional medical help.
To prevent contaminating the paste, DO NOT spread the paste with your nger
directly.

2.3.2 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, make sure that you use only Intel®-certied multi-directional heatsink and fan.
Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
Make sure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.
If you purchased a separate CPU heatsink and fan assembly, ensure that the Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan 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.
2. Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place.
