Chapter 2 Installation

K7S41 / K7S41GX 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 configuration of your chassis to ensure that the motherboard fits into it.
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.

Step 1. Step 2. Step 3.

CPU Installation
Unlock the socket by lifting the lever up to a 90 angle. Position the CPU directly above the socket such that its marked corner matches the base of the socket lever. 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.
Socket Marked Corner Lever 90 Up CPU Marked Corner
STEP 1: Lift Up The Socket Lever
STEP 2/STEP 3: STEP 4: Match The CPU Marked Corner Push Down And Lock to The Socket Marked Corner The Socket Lever
Installation of CPU Fan and Heatsink
This motherboard adopts 462-pin CPU socket to support AMD Athlon XP / Duron CPU. It requires larger heatsink and cooling fan to dissipate 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 7/page 8, No. 2). For proper installation, please kindly refer to the instruction manuals of the CPU fan and the heatsink.

Installation of Memory Modules (DIMM)
K7S41 / K7S41GX motherboard provides two 184-pin DDR (Double Data Rate) DIMM slots. Please make sure to disconnect power supply before adding or removing DIMMs or the system components. Step 1. Step 2. Unlock a DIMM slot by pressing the retaining clips outward. Align a DIMM on the slot such that the notch on the DIMM matches the break on the slot.

notch break

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 the DIMM 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 K7S41 / K7S41GX 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: The AGP slot is used to install a graphics card. The ASRock AGP slot has a special design of clasp that can securely fasten the inserted graphics card.
Please do NOT use a 3.3V AGP card on the AGP 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. Remove the system unit cover (if your motherboard is already installed in a chassis). Remove the bracket facing the slot that you intend to use. Keep the screws for later use. Align the card connector with the slot and press firmly until the card is completely seated on the slot. Fasten the card to the chassis with screws. Replace the system cover.
Step 2. Step 3. Step 4. Step 5. Step 6.

2.5 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 the 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.

For example, Athlon XP 2000+ is an 1666MHz CPU: 12.5 (Multiplier) X 133MHz (External frequency) = 1666MHz FID jumpers setting:
1 FID0 FID1 FID2 FID3 FID4
The jumper caps are not provided by ASRock. Please understand that ASRock does not guarantee and support the adjustment of multiplier. These jumpers setting may not apply to all multiplier-locked or even some unlocked AMD CPU. Frequencies other than the recommended CPU bus frequencies may cause the instability of the system or damage the CPU.

2.6 Connectors

Connectors are NOT jumpers. DO NOT place jumper caps over these connectors. Placing jumper caps over the connectors will cause permanent damage of the motherboard!

Spread Spectrum: This field should always be [Disabled] for better system stability. CPU Host Frequency: [By Jumper]: It is recommended to select this option, which will let the CPU host frequency of this motherboard determined by the jumper-setting. [Manual]: This allows user to set CPU host frequency manually. However, because the CPU host frequency of this motherboard is determined by the jumper-setting, you must set the FSB jumper adjustment according to your AMD CPU before you use this Manual option as the FSB setting in BIOS setup to perform over clocking. This is not recommended unless you thoroughly know the feature. Wrong setup may cause problems during operation. DRAM Frequency: If set to [Auto], the motherboard will detect the inserted memory module(s) and automatically assign appropriate frequency. You may select other value as the operating frequency: [133MHz (DDR266)], [166MHz (DDR333)], [200MHz (DDR400)]. Please note that the option [200MHz (DDR400)] will be available only when K7S41 motherboard is installed. Flexibility Option: The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled].
