Hardware information
ASUS P4SGL-VM motherboard
2.1 Motherboard installation
Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. The P4SGL-VM uses the MicroATX form factor that measures 9.6 inches x 7.5 inches, a standard fit for
most chassis.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause you physical injury and
damage motherboard components.
2.1.1 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. Refer to the image below.
2.1.2 Screw holes
Place six screws into the holes indicated by circles to secure the
motherboard to the chassis.
Do not overtighten the screws! Doing so may damage the
motherboard.
Place this side towards
the rear of the chassis

Chapter 2: Hardware information
2.3 Before you proceed
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. 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.
3. Hold components by the edges and do not to touch the ICs on them.
4. Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
5. 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.

2.4 Central Processing Unit (CPU)
2.4.1 Overview
The motherboard comes with a surface mount 478-pin Zero Insertion
Force (ZIF) socket. This socket is specifically designed for the Intel
Pentium® 4 478/Northwood Processor.
The Intel Pentium 4 Processor in the 478-pin package uses the Flip-Chip
Pin Grid Array 2 (FC-PGA2) package technology, and includes the Intel
NetBurst™ micro-architecture. The Intel NetBurst micro-architecture
features the hyper-pipelined technology, rapid execution engine, 400MHz
system bus, and execution trace cache. Together, these attributes improve
system performance by allowing higher processor frequencies, faster
execution of integer instructions, and a data transfer rate of 3.2GB/s.
Gold Mark
®
®
Note in the illustration that the CPU has a gold triangular mark on one
corner. This mark indicates the processor Pin 1 that should match a
specific corner of the CPU socket.
Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!

Chapter 2: Hardware information
2.4.2 Installing the CPU
Follow these steps to install a CPU.
1. Locate the 478-pin ZIF socket on the motherboard.
2. Unlock the socket by pressing the lever sideways, then lift it up to a
90°-100° angle.
Socket Lever
90 -100
Make sure that the socket lever is lifted up to 90°-100° angle,
otherwise the CPU does not fit in completely.

3. Position the CPU above the socket such that its marked corner
matches the base of the socket lever.
4. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU
into the socket to prevent bending the pins and damaging the CPU!

2.4.3 Installing the heatsink and fan
The Intel® Pentium® 4 478/Northwood Processor requires a specially
designed heatsink and fan assembly to ensure optimum thermal condition
and performance.
When you buy a boxed Intel Pentium 4 478/Northwood Processor, the
package includes the heatsink, fan, and retention mechanism.
In case you buy a CPU separately, make sure that you use only Intel
certified heatsink and fan.
Follow these steps to install the CPU heatsink and fan.
1. Place the heatsink on top of the installed CPU, making sure that the
heatsink fits properly on the retention module base.
The retention module base is already installed on the motherboard
upon purchase.
You do not have to remove the retention module base when installing
the CPU or installing other motherboard components.

Retention Module Base
Your boxed Intel Pentium 4 478/Northwood Processor package should
come with installation instructions for the CPU, heatsink, and the
retention mechanism. If the instructions in this section do not match the
CPU documentation, follow the latter.

Align and snap the four hooks of the retention mechanism to the holes
on each corner of the module base.
Make sure that the fan and retention mechanism assembly perfectly
fits the heatsink and module base, otherwise you cannot snap the
hooks into the holes.
