Chapter 2 Hardware Setup

2.1 Choosing a Computer Chassis

• Choose a chassis big enough to install this motherboard.

• As some features for this motherboard are implemented by cabling connectors on the

motherboard to indicators and switches or buttons on the chassis, make sure your chassis supports all the features required.

• If there is possibility of adopting some more hard drives, make sure your chassis has

sufcient power and space for them.

• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O

shield of the chassis matches the I/O port conguration of this motherboard. You can nd an I/O shield specically designed for this motherboard in its package.

2.2 Installing Motherboard

Most computer chassis have a base with many mounting holes to allow the motherboard to be securely attached, and at the same time, prevent the system from short circuits. There are two ways to attach the motherboard to the chassis base: (1) with studs, or (2) with spacers. Basically, the best way to attach the board is with studs. Only if you are unable to do this should you attach the board with spacers. Line up the holes on the board with the mounting holes on the chassis. If the holes line up and there are screw holes, you can attach the board with studs. If the holes line up and there are only slots, you can only attach with spacers. Take the tip of the spacers and insert them into the slots. After doing this to all the slots, you can slide the board into position aligned with slots. After the board has been positioned, check to make sure everything is OK before putting the chassis back on.

To install this motherboard:

1. Locate all the screw holes on the motherboard and the chassis base.

2. Place all the studs or spacers needed on the chassis base and have them tightened.

3. Face the motherboard’s I/O ports toward the chassis’s rear panel.

4. Line up all the motherboard’s screw holes with those studs or spacers on the chassis.

5. Install the motherboard with screws and have them tightened.

The motherboard and its component layouts illustrated in this chapter are only for reference.

Always power off the computer and unplug the AC power cord before adding or removing any peripheral or component. Failing to do so may cause severe damage to your motherboard and/or peripherals. Plug in the AC power cord only after you have carefully checked everything.

To prevent shorting the motherboard, REMOVE the any unused metal studs or spacers from the chassis.

2.3 Installing CPU and CPU Cooler

Before installing the CPU:

1. Please make sure that the motherboard supports the CPU.

2. Please take note of the indented corners of the CPU. If you install the CPU in the wrong direction, the CPU will not insert properly. If this occurs, please change the insert direction of the CPU.

3. Please add an even layer of thermal paste between the CPU and CPU cooler.

4. Please make sure the CPU cooler is installed on the CPU prior to system use, otherwise overheating and permanent damage of the CPU may occur.

5. Please set the CPU host frequency in accordance with the processor specications. It is not recommended that the system bus frequency be set beyond hardware specications since

it does not meet the required standards for the peripherals. If you wish to set the frequen-

cy beyond the proper specications, please do so according to your hardware specications including the CPU, graphics card, memory, hard drive, etc.

2.3.1 Installation of the CPU

1. Unlock the socket by pressing the lever sideways, then lift it up to a 90o.

2. Position the CPU above the socket such that the CPU corner with the gold triangle matches the socket corner with a small triangle.

3. Carefully insert the CPU into the socket

until it ts place.

4. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.

2.3.2 Installation of the CPU Cooler For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.

2.4 Installation of Memory Modules

This motherboard provides four 240-pin DDRII (Double Data Rate) DIMM slots, and supports

Dual Channel Memory Technology. For dual channel conguration, you always need to install

two identical (the same brand, speed, size and chip-type) memory modules in the DDRII DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single channel mode.

To install system memory:

1. Power off the computer and unplug the AC power cord before installing or removing memory modules.

2. Locate the DIMM slot on the board.

3. Hold two edges of the DIMM module carefully, keep away from touching its connectors.

4. Align the notch key on the module with the rib on the slot.

5. Firmly press the module into the slots until the ejector tabs at both sides of the slot automatically snap into the mounting notch. Do not force the DIMM module in with extra

force as the DIMM module only ts in one direction.

6. To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and then pull out the DIMM module.

Under POWER ON:

• The LED of PWR_LED will light.

• The LED of LED_DIMM1 will light while DIMM1 slocket be installed Memory.

• The LED of LED_DIMM2 will light while DIMM2 slocket be installed Memory.

• The LED of LED_DIMM3 will light while DIMM3 slocket be installed Memory.

• The LED of LED_DIMM4 will light while DIMM4 slocket be installed Memory.

Static electricity can damage the electronic components of the computer or optional boards. Before starting these procedures, ensure that you are discharged of static

electricity by touching a grounded metal object briey.
