CAUTION!
1. 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.
2. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
3. Power Management for USB 2.0 works fine under Microsoft®Windows®
XP SP1/2000 SP4. It may not work properly under Microsoft®Windows®
98/ME. Please refer to Microsoft®official document at
http://www.microsoft.com/whdc/hwdev/bus/USB/USB2support.mspx
4. 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 yourAMDCPU
before you use the “Manual” option as the FSB setting in BIOS setup to
perform over clocking. Please check page 24 of the User Manual in the
Support CD for details.

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.
2.1 CPU Installation2.1 CPU Installation

2.1 CPU Installation
Step 1. Unlock the socket by lifting the lever up to a 90° angle.
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)
K7S41 / K7S41GX motherboard provides two 184-pinDDR (DoubleData Rate) DIMM
slots.
Please make sure to disconnect power supply before adding or removing
DIMMs or the system components.
Step 1. Unlock aDIMM slot by pressing the retaining clips outward.
Step 2. Align aDIMM on the slot such that the notch on the DIMM 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 the DIMM is properly seated.

Note: CLRCMOS1 and CLRCMOS2 allow 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. There are 2 ways for you to clear and reset the system parameters to
the default setup. Please turn off the computer and unplug the power cord, then you may
either short the solder points on CLRCMOS1 by using metal material, e.g., a paper clip for
3 seconds; or you may use a jumper cap to short the pin on CLRCMOS2 for 3 seconds.
Please remember to remove the paper clip or the jumper cap after clearing the CMOS. If
you need to clear the CMOS when you just finish updating the BIOS, you must boot up the
system first, and then shut it down before you do the clear-CMOS action.
