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. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard! It may cause permanent damage! 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 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 of the User Manual in the Support CD for details. 2. 3. 4. 7 ASRock K7S41 / K7S41GX Motherboard English 2. Installation 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. 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 Installation Step 1. Step 2. Step 3. 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. Step 5. 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. Install CPU fan and heatsink. For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink vendors. English 8 ASRock K7S41 / K7S41GX Motherboard 2.2 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. 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. 9 ASRock K7S41 / K7S41GX Motherboard English 2.3 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 bracket facing the slot that you intend to use. Keep the screw 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. Step 2. Step 3. Step 4. English English 10 ASRock K7S41 / K7S41GX Motherboard 2.4 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 Jumpers (see p.2/p.3 No. 27) Short Open Setting K7S41: K7S41GX: Note: The setting of the CPU front side bus frequency of this motherboard is by means of the adjustment of 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 follow the figures above to set the CPU front side bus frequency. PS2_USB_PWR1 (see p.2/p.3 No. 1) Short pin2, pin3 to enable +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. JR1(see p.2/p.3 No. 24) JL1(see p.2/p.3 No. 23) Note: If the jumpers JL1 and JR ...
