Chapter 2. Hardware Setup

Before the Installation: Turn off the power supply switch (fully turn off the +5V standby power), or disconnect the power cord before installing or unplugging any connectors oradd-oncards. Failing to do so may cause the motherboard components oradd-oncards to malfunction or damaged.

2-1.Install The Motherboard

Most computer chassis have a base with many mounting holes to allow motherboard to be securely attached on and at the same time, prevented from short circuits. There are two ways to attach the motherboard to the chassis base:

1.use with studs

2.or use with spacers

In principle, the best way to attach the board is to use 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.

ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they are already fastened on the chassis base and are withoutmounting-holeson the motherboard to align with.

2-2.Install CPU, Heatsink and Fan Assembly

In order to protect the contact pins, please pay attention to these notices:

1.A maximum 20 cycles of CPU installation is recommended.

2.Never touch the contact pins with fingers or any object.

3.Always put on the cap when the CPU is not in use.

1. Place the board so as to let the lever hook of the socket is on your left side. Use your left thumb and forefinger to hold the lever hook, pull it away from the retention tab.

4. Use your right thumb and forefinger to grasp the CPU package. Be sure to grasp on the edge of the substrate, and face thePin-1indicator toward thebottom-leftside. Aim at the socket and place the CPU package vertical down into the socket.

5. Visually inspect if the CPU is seated well into the socket. The alignment key must be located in the notch of package.

2.Rotate the lever to fully open position.

3. Use your right thumb on thebottom-rightside of the load plate and lift it up to fully open position.

6. Use your left hand to hold the load plate, and use your right thumb to peel the cap off.

The cap plays an important role in protecting contact pins. In order to prevent bent pin, PUT ON the cap after operation or testing.

For detailed information on how to install your heatsink and fan assembly, please refer to the instruction manual came packed with the heatsink and fan assembly you bought.

7. Lower the plate onto the CPU package. Engage the load lever while gently pressing down the load plate.

8. Secure the lever with the hook under retention tab.

9. Place the heatsink and fan assembly onto the socket. Align the four fasteners toward the four mounting holes on the motherboard.

10. Press each of the four fasteners down into the mounting holes.

11. Rotate the fastenerclock-wiseto lock the heatsink and fan assembly into position.

12. Attach thefour-pinpower plug from the heatsink and fan assembly to the CPU FAN connector.

2-3.Install System Memory

This motherboard provides four 240-pinDIMM slots for Dual Channel DDR2 533/400 memory modules with memory expansion size up to 4GB.

To reach the optimum performance in dual-channelconfigurations, install identical DDR2 DIMM pairs for each channel.

Install DIMMs with the same CAS latency. To reach the optimum compatibility, obtain memory modules from the same vendor.

Due to chipset resource allocation, the system may detect less than 4GB of system memory in the installation of four 1GB DDR2 memory modules.

Due to chipset limitation, 128MB DIMM modules or double-sidedx16 memory chips are not supported.

There are several methods of different DDR2 configurations depending on how the DIMMs are populated on each system memory channel:

[Single Channel]: only one channel is populated.

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

1.Locate the DIMM slot on the board.

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

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

4.Firmly press the module into the slots until the ejector tabs at both sides of the slot

automatically snaps into the mounting notch. Do not force the DIMM module in with extra force as the DIMM module only fit in one direction.

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

ATTENTION: 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 briefly.
