1-3 Installation of the CPU and Heatsink

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 corner 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-8I945GMBX Motherboard - 12 -

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

1-3-2 Installation of the Fan Heatsink

Fig.1 Apply an even layer of thermal paste on the surface of the installed CPU.

Fig.2 Install the motherboard in the chassis. Align the fan heatsink with the screw holes and place it onto the motherboard.

Fig.3 Fasten the fan heatsink with screws. Assure that the fan heatsink is securely attached to the motherboard and chassis. (For detailed installation instructions, please refer to the user's manual for your fan heatsink.)

English

Fig.4 Finally, please attach the power connector of the fan heatsink to the CPU fan header located on the motherboard.

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

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 DDR II 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.

DDRII

Notch

Fig.1 The DIMM socket has a notch, so the DIMM memory module can only fit in one direction. Insert the DIMM memory module vertically into the DIMM socket. Then push it down.

Fig.2 Close the plastic clip at both edges of the DIMM sockets to lock the DIMM module. Reverse the installation steps when you wish to remove the DIMM module.

GA-8I945GMBX Motherboard - 14 -

Dual Channel DDR II Memory Configuration

The GA-8I945GMBX supports the Dual Channel Technology. When the Dual Channel Technology is activated, the bandwidth of memory bus will be double the original one.

The GA-8I945GMBX includes 4 DIMM sockets, and each Channel has 2 DIMM sockets as following:

Channel A : DDR II 1, DDR II 2

Channel B : DDR II 3, DDR II 4 Due to chipset limitation, if you want to operate the Dual Channel Technology, please follow the guidelines below for Dual Channel memory configuration.

1. Dual channel memory cannot be used if one or three DDR II memory modules are installed.

2. If two DDR II memory modules are installed (same storage capacity), one must be added to the Channel A slot and the other in the Channel B slot in order to use dual channel memory. Dual channel memory cannot function if both DDR II memory modules are installed on the same channel.

3. If four DDR II memory modules are installed, please use memory of the same storage capacity in order to use dual channel memory and for BIOS to detect all the DDR II memory modules.

We'll strongly recommend our user to slot two DDR II memory modules into the DIMMs with the same color in order for Dual Channel Technology to work.

The following is a Dual Channel Memory configuration table: (DS: Double Side, SS: Single Side)

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

2. Remove your computer's chassis cover, 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.

Installing a PCI Express x 16 expansion card:

Please carefully pull out the small whitedrawable bar at the end of the PCI Express x 16 slot when you try to install/uninstall the VGA card. Please align the VGA card to the onboard PCI Express x 16 slot and press firmly down on the slot. Make sure your VGA card is locked by the small white-drawable bar.

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. If you use a 24-pin ATX power supply, please remove the small cover on the power connector on the motherboard before plugging in the power cord ; Otherwise, please do not remove it.
