Chapter 1: Product introduction
1.3.2 Value-added solutions
Easy overclocking
• adjustable CPU frequency multiple in BIOS using the ASUS
JumperFree™ solution
• adjustable FSB/PCI/memory frequency ratios
• Stepless Frequency Selection (SFS) for fine-tuning system bus at 1MHz
increments
Concurrent PCI
This feature allows multiple PCI transfers from PCI master buses to the
memory and processor.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored by the ASUS ASIC through the CPU’s
internal diode to prevent overheating and damage. The system fan
rotations per minute (RPM) is monitored for timely failure detection. The
system voltage levels are monitored to ensure stable supply of current for
critical components.
Dual function power switch
While the system is ON, pressing the power switch for less than 4 seconds
puts the system to sleep mode or to soft-off mode, depending on the BIOS
setting. Pressing the power switch for more than 4 seconds lets the
system enter the soft-off mode regardless of the BIOS setting.
ACPI ready
The Advanced Configuration power Interface (ACPI) provides more energy
saving features for operating systems that support OS Direct Power
Management (OSPM).

ASUS P4SDR-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 P4SDR-VM uses the
micro-ATX form factor that measures 9.6 inches x 7.5 inches (24.5x19cm).
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 as indicated in the image below.
2.1.2 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 may damage the
motherboard.
Place this side towards
the rear of the chassis

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 to avoid touching 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.
When lit, the standby power LED (SBPWRLED1) indicates that the
system is ON, in sleep mode, or in soft-off mode, a reminder that you
should shut down the system before removing or plugging in any
motherboard component.

2.4 Central Processing Unit (CPU)
2.4.1 Overview
The motherboard comes with a surface mount 478-pin Zero Insertion
Force (ZIF) socket. The socket is designed for the Intel Pentium 4
Processor in the 478-pin package with 512KB/256KB L2 cache on 0.13
micron process. This processor includes the Intel® NetBurst™ microarchitecture that features the hyper-pipelined technology, rapid execution
engine, 100 MHz system bus, and execution trace cache. Together, these
attributes improve system performance by allowing higher core
frequencies, faster execution of integer instructions, and 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!

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.

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!

5. When the CPU is in place, press it firmly on the socket while you push
down the socket lever to secure the CPU. The lever clicks on the side
tab to indicate that it is locked.

2.4.3 Installing the heatsink and fan
The Intel® Pentium® 4 Processor requires a specially designed heatsink
and fan assembly to ensure optimum thermal condition and performance.
When you buy a boxed Intel Pentium 4 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 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.

2. Position the fan with the retention mechanism on top of the heatsink.
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.
