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.
2.1 CPU Installation Step 1. Step 2. 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. Step 3. o The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to avoid bending of the pins. Step 4.
2.3 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 notch break The DIMM only fits in one correct orientation.
2.4 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.
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. Jumper FSB Select Setting K7S41: Jumpers (see p.7/p.8 No.
Clear CMOS (CLRCMOS1, solder points) (see p.7/p.8 No. 11) (CLRCMOS2, 2-pin jumper) (see p.7/p.8 No. 12) solder points 2-pin jumper 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.
For example, “Athlon XP 2000+” is an 1666MHz CPU: 12.5 (Multiplier) X 133MHz (External frequency) = 1666MHz FID jumpers setting: 1 FID0 1 FID1 1 FID2 1 FID3 1 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.
