WARNING
Please realize that there is a certain risk involved with overclocking, including adjusting
the setting in the BIOS, applying Untied Overclocking Technology, or using the third-
party overclocking tools. Overclocking may affect your system stability, or even
cause damage to the components and devices of your system. It should be done at
your own risk and expense. We are not responsible for possible damage caused by
overclocking.

CAUTION!
1. If you adopt FSB400-CPU on this motherboard, you need to adjust the
jumpers. Please refer to page 11 for proper jumper settings.
2. About the setting of “Hyper Threading Technology”, please check page 26
of “User Manual” in the support CD.
3. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 16 for details.
4. Please check the table below for the CPU FSB frequency and its corre-
sponding memory support frequency.
CPU FSB Frequency Memory Support Frequency
800 DDR2 400, DDR2 533, DDR2 667
533 DDR2 400, DDR2 533
400 DDR2 400
5. Due to the chipset limitation, the actual memory size may be less than
4GB for the reservation for system usage under Windows®XP and
Windows®VistaTM.
6. The maximum shared memory size is defined by the chipset vendor and
is subject to change. Please check Intel®website for the latest information.
7. For microphone input, this motherboard supports both stereo and mono
modes. For audio output, this motherboard supports 2-channel, 4-channel,
6-channel, and 8-channel modes. Please check the table on page 3 for
proper connection.
8. Before installing SATAII hard disk to SATAII connector, please read the “SATAII
Hard Disk Setup Guide” on page 20 of “User Manual” in the support CD to
adjust your SATAII hard disk drive to SATAII mode. You can also connect SATA
hard disk to SATAII connector directly.
9. Power Management for USB 2.0 works fine under Microsoft®Windows®
VistaTM / XP SP1 or SP2 / 2000 SP4.
10. ASRock Instant Flash is a BIOS flash utility embedded in Flash ROM.
This convenient BIOS update tool allows you to update system BIOS
without entering operating systems first like MS-DOS or Windows®. With
this utility, you can press <F6> key during the POST or press <F2> key to
BIOS setup menu to access ASRock Instant Flash. Just launch this tool
and save the new BIOS file to your USB flash drive, floppy disk or hard
drive, then you can update your BIOS only in a few clicks without prepar-
ing an additional floppy diskette or other complicated flash utility. Please
be noted that the USB flash drive or hard drive must use FAT32/16/12 file
system.
11. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
12. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.

Pre-installation Precautions
Take note of the following precautions before you install mother-
board components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
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
antstatic pad or in the bag that comes with the component.

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.
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.
Step 5. Install CPU fan and heatsink. For proper installation, please kindly refer to
the instruction manuals of your CPU fan and heatsink vendors.

2.2 Installation of Memory Modules (DIMM)
P4i945GC motherboard provides two 240-pin DDR2 (Double Data Rate 2) DIMM
slots.
1. It is not allowed to install a DDR memory module into DDR2 slot;
otherwise, this motherboard and DIMM may be damaged.
2. Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
•
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 theDIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause
permanent damage to the motherboard and the DIMM if you
force the DIMM into the slot at incorrect orientation.
Step 3. Firmly insert theDIMM into the slot until the retaining clips at both ends fully
snap back in place and theDIMM is properly seated.

PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.2 No. 1) +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.
ClearCMOS
(CLRCMOS1, 2-pin jumper)
(see p.2 No. 9)
Note: CLRCMOS1 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 from the power
supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on
CLRCMOS1 for 5 seconds.

This motherboard supports Untied Overclocking Technology, which means during
overclocking, FSB enjoys better margin due to fixed PCI / PCIE buses. Before you
enable Untied Overclocking function, please enter “Overclock Mode” option of BIOS
setup to set the selection from [Auto] to [CPU, PCIE,Async.]. Therefore, CPU FSB is
untied during overclocking, but PCI / PCIE buses are in the fixed mode so that FSB can
operate under a more stable overclocking environment.
Please refer to the warning on page 6 for the possible overclocking risk before
you apply Untied Overclocking Technology.
