7 Chapter 2 Installing the Motherboard Safety Precautions • • • • • Follow these safety precautions when installing the motherboard Wear a grounding strap attached to a grounded device to avoid damage from static electricity Discharge static electricity by touching the metal case of a safely grounded object before working on the motherboard Leave components in the static-proof bags they came in Hold all circuit boards by the edges.
8 Do not over-tighten the screws as this can stress the motherboard. Checking Jumper Settings This section explains how to set jumpers for correct configuration of the motherboard. Setting Jumpers Use the motherboard jumpers to set system configuration options. Jumpers with more than one pin are numbered. When setting the jumpers, ensure that the jumper caps are placed on the correct pins. The illustrations show a 2-pin jumper. When the jumper cap is placed on both pins, the jumper is SHORT.
9 Checking Jumper Settings The following illustration shows the location of the motherboard jumpers. Pin 1 is labeled. Jumper Settings Jumper Type Description Setting (default) 1-2: NORMAL 2-3: CLEAR CMOS Before clearing the CMOS, make sure to turn off the system.

10 Installing Hardware Installing the Processor Caution: When installing a CPU heatsink and cooling fan make sure that you DO NOT scratch the motherboard or any of the surfacemount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes across the motherboard, you may cause serious damage to the motherboard or its components. On most motherboards, there are small surface-mount resistors near the processor socket, which may be damaged if the cooling fan is carelessly installed.
11 CPU Installation Procedure The following illustration shows CPU installation components. A. Read and follow the instructions shown on the sticker on the CPU cap. B. Unload the cap · Use thumb & forefinger to hold the lifting tab of the cap. · Lift the cap up and remove the cap completely from the socket. C. Open the load plate · Use thumb & forefinger to hold the hook of the lever, pushing down and pulling aside unlock it. · Lift up the lever. · Use thumb to open the load plate.
12 Installing Memory Modules This motherboard accommodates four memory modules. It can support four 240-pin DDR2 800/667. The total memory capacity is 4 GB. DDR2 SDRAM memory module table Memory module DDR2 667 DDR2 800 Memory Bus 333 MHz 400 MHz You must install at least one module in any of the four slots. Each module can be installed with 1 GB of memory; total memory capacity is 4 GB. Do not remove any memory module from its antistatic packaging until you are ready to install it on the motherboard.
13 Due to chipset limitation, please follow closely the table below when installing memory for dual channel or single channel mode operation. Memory Installation Combination For dual channel configuration, you must always install identical (the same board, speed, size and chip-type) DDR2 DIMM pair in the slots of the same color.
14 Table A: DDR2 (memory module) QVL (Qualified Vendor List) The following DDR2 800/667 memory modules and combination have been tested and qualified for use with this motherboard.
15 Expansion Slots Installing Add-on Cards The slots on this motherboard are designed to hold expansion cards and connect them to the system bus. Expansion slots are a means of adding or enhancing the motherboard’s features and capabilities. With these efficient facilities, you can increase the motherboard’s capabilities by adding hardware that performs tasks that are not part of the basic system.
16 Follow these instructions to install an add-on card: 1 2 3 Remove a blanking plate from the system case corresponding to the slot you are going to use. Install the edge connector of the add-on card into the expansion slot. Ensure that the edge connector is correctly seated in the slot. Secure the metal bracket of the card to the system case with a screw. 1.
