Hardware information
ASUS P4S8X motherboard
2.1Motherboard installation
Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. The P4S8X uses the ATX form
factor that measures 30.5 cm (12.0 in.) x 21.9 cm (8.6 in.), 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.
2.1.1Placement 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.
2.1.2Screw holes
Place seven (7) 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

2.3Before 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.
Onboard System Indicators (LED - Light Emitting Diodes)
The GREEN onboard LED indicates that the system power is okay. This
light also lights when the PC is in suspend or soft-off mode. The RED
onboard warning LED lights up only if the wrong type of AGP card is
connected to the board: (See AGP 8X, p. 23)

2.4Central Processing Unit (CPU)
2.4.1Overview
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, 400 /
533MHz 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 rates of 3.2 and
4.2GB/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!
ASUS P4S8X motherboard user guide
11
2.4.2Installing 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
12
Make sure that the socket lever is lifted up to 90°-100° angle,
otherwise the CPU does not fit in completely.
Chapter 2: Hardware information
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!
Gold Mark
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.

2.4.3Installing 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.
CPU Heatsink
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.
14
Chapter 2: Hardware information
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.
Retention Hole
Retention Lock
Keep the retention locks lifted upward while fitting the retention
mechanism to the module base.

3.Push down the locks on the retention mechanism to secure the
heatsink and fan to the module base.
When secure, the retention locks should point to opposite directions.
2.4.4Connecting the CPU fan cable
When the fan, heatsink, and the retention mechanism are in place,
connect the CPU fan cable to the connector on the motherboard labeled
CPUFAN.
CPU Fan Connector (CPUFAN)
16
Don’t forget to connect the CPU fan connector! Hardware monitoring
errors may occur if you fail to plug this connector.
Chapter 2: Hardware information
2.5System memory
2.5.1Overview
The motherboard comes with three Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets. These sockets support up to 3GB
system memory using 184-pin unbuffered non-ECC PC2700/2100/1600
DIMMs.
104 Pins
P4S8X
®
P4S8X 184-Pin DDR DIMM Sockets
A DDR DIMM is keyed with a notch so that it fits in only one direction.
DO NOT force a DIMM into a socket to avoid damaging the DIMM.
80 Pins
The DDR SDRAM technology evolved from the mainstream PC66, PC100,
PC133 memory known as Single Data Rate (SDR) SDRAM. DDR memory
however, has the ability to perform two data operations in one clock cycle,
thus providing twice the throughput of SDR memory.
DDR Data Transfer RateDDR Base Frequency
2.7 GB/s166MHz
2.1 GB/s133MHz
1.6 GB/s100MHz
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should
be installed only in a socket specially designed for DDR DIMMs.
ASUS P4S8X motherboard user guide
17
2.5.2Memory configurations
You may install any DDR DIMMs with 64MB, 128MB, 256MB, 512MB and
1GB densities into the three DIMM sockets.
DDR DIMMs may be installed in the following sizes:
Use only the tested and qualified DDR333 DIMMs listed above. Other
DDR DIMMs manufactured by other vendors may not be suitable for
this motherboard. Visit the ASUS website for the latest qualified DDR
module list.
