1-3 Installation of the CPU and CPU Cooler

English

Before installing the CPU, please comply with the following conditions:

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

2. Please take note of the one indented corner 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 heat sink paste between the CPU and heatsink.

4. Please make sure the heatsink 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 specifications. It is not recommended that the system bus frequency be set beyond hardware specifications since it does not meet the required standards for the peripherals. If you wish to set the frequency beyond the proper specifications, please do so according to your hardware specifications including the CPU, graphics card, memory, hard drive, etc.

HT functionality requirement content :

Enabling the functionality of Hyper-Threading Technology for your computer system requires all of the following platform components:

- CPU: An Intel® Pentium 4 Processor with HT Technology

- Chipset: An Intel® Chipset that supports HT Technology

- BIOS: A BIOS that supports HT Technology and has it enabled

- OS: An operation system that has optimizations for HT Technology

1-3-1 Installation of the CPU

Metal Lever

Fig. 1 Gently lift the metal lever located on the CPU socket to the upright position.

Fig. 2 Remove the plastic covering on the CPU socket.

Fig. 3 Notice the small gold colored triangle located on the edge of the CPU socket. Align the indented cor-

ner of the CPU with the triangle and gently insert the CPU into position. (Grasping the CPU firmly between your thumb and forefinger, carefully place it into the socket in a straight and downwards motion. Avoid twisting or bending motions that might cause damage to the CPU during installation.)

GA-VM800PMC Motherboard - 12 -

Fig. 4 Once the CPU is properly inserted, please replace the plastic covering and push the metal lever back into its original position.

1-3-2 Installation of the CPU Cooler

English

Male Push Pin

The top of Female Push Pin

Female Push Pin

Fig.1 Please apply an even layer of CPU cooler paste on the surface of the installed CPU.

Fig. 3 Place the CPU cooler atop the CPU and make sure the push pins aim to the pin hole on the motherboard.Pressing down the push pins diagonally.

Fig. 5 Please check the back of motherboard after installing. If the push pin is inserted as the picture, the installation is complete.

Fig. 2 (Turning the push pin along the direction of arrow is to remove the CPU cooler, on the contrary, is to install.) Please note the direction of arrow sign on the male push pin doesn't face inwards before installation. (This instruction is only for Intel boxed fan)

Fig. 4 Please make sure the Male and Female push pin are joined closely. (for detailed installation instructions, please refer to the CPU cooler installation section of the user manual)

Fig. 6 Finally, please attach the power connector of the CPU cooler to the CPU fan header located on the motherboard.

The CPU cooler may adhere to the CPU as a result of hardening of the heat paste. To prevent such an occurrence, it is suggested that either thermal tape rather than heat paste be used for heat dissipation or using extreme care when removing the CPU cooler.

1-4 Installation of Memory

Before installing the memory modules, please comply with the following conditions:

1. Please make sure that the memory used is supported by the motherboard. It is recommended that memory of similar capacity, specifications and brand be used.

2. Before installing or removing memory modules, please make sure that the computer power is switched off to prevent hardware damage.

3. Memory modules have a foolproof insertion design. A memory module can be installed in only one direction. If you are unable to insert the module, please switch the direction.

The motherboard supports DDRII/DDR memory modules, whereby BIOS will automatically detect memory capacity and specifications. Memory modules are designed so that they can be inserted only in one direction. The memory capacity used can differ with each slot.

With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, please make sure that all components and devices are properly installed. Align the power connector with its proper location on the motherboard and connect tightly. The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V power connector is not connected, the system will not start. Caution! Please use a power supply that is able to handle the system voltage requirements. It is recommended that a power supply that can withstand high power consumption be used (300W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable system or a system that is unable to start.

18) BATTERY

If you want to erase CMOS...

1. Turn off the computer and unplug the power cord.

2. Gently take out the battery and put it aside for about one minute.

3. Re-install the battery.

4. Plug the power cord in and turn on the computer.

GA-VM800PMC Motherboard - 26 -

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type recommended

by the manufacturer.

Dispose of used batteries according to the manufacturer's

instructions.

(Or you can use a metal object to connect the positive and

negative pins in the battery holder to make them short for five

seconds.)

Chapter 2 BIOS Setup

BIOS (Basic Input and Output System) includes a CMOS SETUP utility which allows user to configure required settings or to activate certain system features. The CMOS SETUP saves the configuration in the CMOS SRAM of the motherboard. When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS SRAM. When the power is turned on, pushing the <Del> button during the BIOS POST (Power-On Self Test) will take you to the CMOS SETUP screen. You can enter the BIOS setup screen by pressing "Ctrl + F1". If you wish to upgrade to a new BIOS, either Gigabyte's Q-Flash or @BIOS utility can be used. Q-Flash allows the user to quickly and easily update or backup BIOS without entering the operating system. @BIOS is a Windows-based utility that does not require users to boot to DOS before upgrading BIOS but directly download and update BIOS from the Internet.
