WARNING!

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To

protect them against damage from static electricity, you should follow some precautions whenever you

work on your computer.

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do not have

one, touch both of your hands to a safely grounded object or to a metal object, such as

the power supply case.

3. Hold components by the edges and try not touch the IC chips, leads or connectors, or

other components.

4. Place components on a grounded antistatic pad or on the bag that came with the

components whenever the components are separated from the system.

5. Ensure that the ATX power supply is switched off before you plug in or remove the ATX

power connector on the motherboard.

If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are

no slots to attach the spacers, do not become alarmed you can still attach the spacers to the mounting

holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so be careful

of your hands). In this way you can still attach the motherboard to the base without worrying about short

circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard

PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact

any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the

board or cause board malfunctioning.

Introduction

 Please set the CPU host frequency in accordance with your processor’s specifications.

We don’t recommend you to set the system bus frequency over the CPU’s specification

because these specific bus frequencies are not the standard specifications for CPU,

chipset and most of the peripherals. Whether your system can run under these specific

bus frequencies properly will depend on your hardware configurations, including CPU,

Chipsets,SDRAM,Cards….etc.

Socket Actuation Lever

1. Pull up the CPU socket level

and up to 90-degree angle.

Pin1 indicator

2. Locate Pin 1 in the socket and look

for a (golden) cut edge on the CPU

upper corner. Then insert the CPU

into the socket.

For example: The newest Pentium III processor (FC-PGA2 package).

 Please make sure the CPU type is supported by the motherboard.

 If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause

improper installation. Please change the insert orientation.

12

Step1-3:CPU Heat Sink Installation

3. Fasten the heatsink supporting-base

onto the CPU socket on the main-

board.

2. Use qualified fan approved by Intel.

4. Make sure the CPU fan is

plugged to the CPU fan connector,

than install complete.

1. Press down the CPU socket

lever and finish CPU installation.

 Please use Intel approved cooling fan.

 We recommend you to apply the thermal paste to provide better heat

conduction between your CPU and heatsink.

 Make sure the CPU fan power cable is plugged in to the CPU fan connector,

this completes the installation.

 Please refer to CPU heat sink user’s manual for more detail installation

procedure.

13

Hardware Installation Process

Step 2: Install memory modules

The motherboard has 2 dual in-line memory module (DIMM) sockets support 4 banks. The BIOS will

automatically detects memory type and size. To install the memory module, just push it vertically into the

DIMM Slot .The DIMM module can only fit in one direction due to the two notch. Memory size can vary

between sockets.

1. The DIMM slot has two notch, so the

DIMM memory module can only fit in

one direction.

2. Insert the DIMM memory module

vertically into the DIMM slot. Then

push it down.

3. Close the plastic clip at both edges of the DIMM slots to lock the DIMM module.

Reverse the installation steps when you wish to remove the DIMM module.

SDRAM

 When STR/DIMM LED is ON, do not install/remove SDRAM from socket.

 Please note that the DIMM module can only fit in one direction due to the two

notches. Wrong orientation will cause improper installation. Please change

the insert orientation.

14

GA-6VEM Series Motherboard

Step 3: Install expension cards

1. Read the related expansion card’s instruction document before install the expansion card into

the computer.

2. Remove your computer’s chassis cover, necessary screws and slot bracket from the computer.

3. Press the expansion card firmly into expansion slot in motherboard.

4. Be sure the metal contacts on the card are indeed seated in the slot.

5. Replace the screw to secure the slot bracket of the expansion card.

6. Replace your computer’s chassis cover.

7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.

8. Install related driver from the operating system.

 When you try to install VGA Card, please note that the motherboard only

support AGP 4X(1.5V) VGA Card.
