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. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
2. The maximum shared memory size is defined by the chipset vendor and
is subject to change. Please check SiS®website for the latest information.
3. Power Management for USB 2.0 works fine under Microsoft®Windows®
XP SP1 or SP2 / 2000 SP4.
4. Featuring an advanced proprietary hardware and software design,
Intelligent Energy Saver is a revolutionary technology that delivers
unparalleled power savings.
5. 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.
6. 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. The CPU host frequency of this motherboard is determined by the
jumper-setting. You must set the FSB jumper according to your AMD CPU
before you use the “Manual” option as the FSB setting in BIOS setup to
perform over clocking. Please check page 24 for details.
7. 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.

8. EuP, stands for Energy Using Product, was a provision regulated by European
Union to define the power consumption for the completed system. According
to EuP, the total AC power of the completed system shall be under 1.00W in
off mode condition. To meet EuP standard, an EuP ready motherboard and an
EuP ready power supply are required. According to Intel’s suggestion, the EuP
ready power supply must meet the standard of 5v standby power efficiency
is higher than 50% under 100 mA current consumption. For EuP ready power
supply selection, we recommend you checking with the power supply manu-
facturer for more details.

Chapter 2 Installation
K7S41GX2 is a Micro ATX form factor (9.6-in x 7.8-in, 24.4 cm x 19.8 cm)
motherboard. Before you install the motherboard, please study the configura-
tion of your chassis to ensure that the motherboard fits into it.
Pre-installation PrecautionsPre-installation Precautions
Pre-installation PrecautionsPre-installation Precautions
Pre-installation Precautions
Take note of the following precautions before you install motherboard compo-
nents 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 re-
member 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.

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.

Installation of CPU Fan and Heatsink
This motherboard adopts 462-pin CPU socket to supportAMDAthlon
XP / DuronCPU. It requires larger heatsink and cooling fan to dissi-
pate heat. You also need to spray thermal grease between the CPU
and the heatsink to improve heat dissipation. Make sure that the CPU
and the heatsink are securely fastened and in good contact with
each other. Then connect the CPU fan to the CPU_FAN connector
(CPU_FAN1, see page 10, No. 2). For proper installation, please
kindly refer to the instruction manuals of the CPU fan and the heatsink.

K7S41GX2 motherboard provides two 184-pinDDR (Double Data Rate) DIMM slots.
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 aDIMM 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 theDIMM 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 the DIMM is properly seated.

Expansion Slots (PCI, AMR, and AGP Slots)
There are 2 PCI slots, 1 AMR slot, and 1 AGP slot on K7S41GX2 motherboard.
PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
AMR slot: The AMR slot is used to insert an ASRock MR card (optional) with
v.92 Modem functionality.
AGP slot: TheAGP slot is used to install a graphics card. TheASRockAGP slot has
a special design of clasp that can securely fasten the inserted graphics
card.
Please doNOT use a 3.3VAGP card on theAGP slot of this motherboard!
It may cause permanent damage! For the voltage information of your
graphics card, please check with the graphics card vendors.

Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
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 screws 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.
