CAUTION!
1. P4I45G/P4I45GL/P4I45GE motherboard may be fine tuned to support higher
CPU bus frequencies on certain condition. Please refer to the tables on
pages 7-9 for the details.
2. About the setting of “Hyper Threading Technology”, please check
page 26.
3. If the installed CPU runs with the front side bus frequency at 533 MHz on
P4i45GL motherboard, it will only support DDR 266.
4. While CPU overheat is detected, the system will automatically shutdown.
Please check if the CPU fan on the motherboard functions properly before
you resume the system. To improve heat dissipation, remember to spray
thermal grease between the CPU and the heatsink when you install the
PC system.
5. Do NOT plug a 3.3VAGP card in the AGP slot on P4i45G/P4i45GE
motherboard! It may cause permanent damage!
6. Power Management for USB 2.0 works fine under Microsoft®Windows®
XP. It may not work properly under Microsoft®Windows®98/ME/2000.
Please refer to Microsoft®official document at
http://www.microsoft.com/HWDEV/BUS/usb/USB2support.asp
7. Although P4i45G / P4i45GL / P4i45GV / P4i45GE offers stepless control,
it is not recommended to perform over clocking. When the CPU
frequency of P4i45G / P4i45GL / P4i45GV / P4i45GE is set to perform
over clocking, other clocks, such as PCI clock, AGP clock, and Memory
clock will also be overclocked proportionally. Frequencies other than the
recommended CPU bus frequencies may cause the instability of the
system or damage the CPU and the motherboard.

7
NOTE
P4i45G, P4i45GL, and P4i45GE may be fine tuned to support higher CPU front side bus
frequencies on certain condition. Please refer to the table below for the details.
CPU FSB Configuration Note
P4i45G 800 MHz 1. Set the “FSB” jumper to “TEST” mode (see page 18).
2. Only support one DDR 333 memory module.
P4i45GL 533 MHz Only support DDR 266 memory module.
P4i45GE 800 MHz 1. Set the “FSB” jumper to “TEST” mode (see page 18).
2. Only support one DDR 400 memory module.
(If it is set to DDR 400 mode, then it does not
support CL3 module.)

Chapter 2 Installation
P4i45G / P4i45GL / P4i45GV / P4i45GE is a Micro ATX form factor (9.6" x 9.6", 24.4 x
24.4 cm) motherboard. Before you install the motherboard, study the configuration
of your chassis to ensure that the motherboard fits into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.
2.1 Screw Holes
Place screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over-tighten the screws! Doing so may damage the
motherboard.
2.2 Pre-installation Precautions
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. To avoid damaging the motherboard components due to static electricity, NEVER
place your motherboard directly on the carpet or the like. Also remember to use
a grounded wrist strap or touch a safety grounded object before you handle
components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
Before you install or remove any component, ensure that the power 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.
2.3 CPU Installation
Step 1. Unlock the socket by lifting the lever up to a 90oangle.
Step 2. Position the CPU directly above the socket such that its marked corner
matches the base of the socket lever.
Step 3. Carefully insert the CPU into the socket until it fits in place.

16
168-pin RAM 184-pin RAM
The CPU fits only in one correct orientation. DO NOT force the
CPU into the socket to avoid bending of the pins.
Step 4. 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.
Step1 Step 2, 3 Step 4
2.4 Installation of CPU Fan and Heatsink
Intel®Pentium®4 CPU requires larger heatsink and cooling fan. Thermal grease
between the CPU and the heatsink is also needed to improve heat dissipation.
Make sure that the CPU and the heatsink are securely fastened and in good
contact with each other. For proper installation, please kindly refer to the
instruction manuals of the CPU fan and heatsink vendors.
2.5 Installation of Memory Modules (DIMM)
SDRAM (Synchronous DRAM) DIMM (Dual In-line Memory Module) has 168
pins and DDR (Double Data Rate) SDRAM DIMM has 184 pins. There are two
SDRAMDIMM slots (black) and twoDDRDIMM slots (blue) provided on P4i45G,
P4i45GL, and P4i45GV motherboards. On P4i45GE motherboard, only 2 DDR
DIMM slots and NO SDRAM DIMM SLOTS are provided.
Please make sure to disconnect power supply before adding
or removing DIMMs or the system components.
The 168-pin SDRAM DIMM slot (black) and 184-pin DDR DIMM slot (blue) can
be easily distinguished by the fool-proof design.
Please do not use both 168-pin SDRAM DIMM and 184-pin
DDR DIMM at the same time. To optimize the compatibility, it
is not recommended to use two different models of the DIMMs
at the same time.

17
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
Step 3. Firmly insert the DIMM into the slot until the retaining clip snap back in place
and the DIMM is properly seated.
2.6 Expansion Slots (PCI, AMR, and AGP Slots)
There are 3 PCI slots and 1 AMR slot on P4i45G, P4i45GL, P4i45GV, and P4i45GE
motherboards. Additionally, there is 1 AGP slot on P4i45G and P4i45GE.
PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
AMR slot: AMR slot is used to insert ASRock MR card with v.92 Modem
functionality.
AGP slot (only available on P4i45G/P4i45GE Motherboard):
The AGP slot is used to install a graphics card.
The ASRock AGP slot has a special locking mechanism which can
securely fasten the graphics card inserted.
Please do NOT plug a 3.3V AGP card in the AGP slot on P4i45G/
P4i45GE motherboard! It may cause permanent damage!
Installing an expansion card
Step 1. Before installing the expansion card, read the documentation of the
expansion card and make necessary hardware settings for the card.
Step 2. Remove the system unit cover (if your motherboard is already
installed in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screw for later use.
Step 4. Align the card connector with the slot and press firmly until the card
is completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

2.7 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “SHORT”. If no jumper
cap is placed on pins, the jumper is “OPEN”.
The illustration shows a 3-pin jumper whose
pin1 and pin2 are “SHORT” when jumper cap
is placed on these 2 pins.
Jumper Setting Description
FSB “NORMAL” (short pin1, pin2)
(see p.10 / p.13 item 28) is the default setting for the
(for P4i45G / P4i45GE FSB jumper. “TEST” (short
motherboardonly) pin2, pin3) is the setting for
the over clocking of CPU
frequency.
PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.10-p.13 item 22) +5VSB (standby) for PS/2
or USB wake up events.
Note:To select +5VSB, it requires 2 Amp and higher standby current provided
by power supply.
Clear CMOS
CLRCMOS0
(see p.10-p.13 item 17)
Note:CLRCMOS0 allows you to clear the data in CMOS. The data in CMOS
includes system setup information such as system password, date, time,
and system setup parameters. To clear and reset the system parameters to
default setup, please turn off the computer and unplug the power cord, then
use a jumper cap to short the pins on CLRCMOS0 for 3 seconds.
Please remember to remove the jumper cap after clearing the CMOS.
