1-3 Installation of the CPU and CPU Cooler

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 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 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

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 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.

Notch

DDRII

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.

Dual Channel Memory Configuration

The GA-945GM-S2 / GA-945GMF-S2 supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of memory bus will double.

The GA-945GM-S2 / GA-945GMF-S2 includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:

Channel 0 : DDRII1, DDRII2

Channel 1 : DDRII3, DDRII4

If you want to operate the Dual Channel Technology, please note the following explanations due to the limitation of Intel chipset specifications.

1.Dual Channel mode will not be enabled if only one DDRII memory module is installed.

2.To enable Dual Channel mode with two or four memory modules (it is recommended to use memory modules of identical brand, size, chips, and speed), you must install them into DIMM sockets of the same color.

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

	DDR II1	DDR II2	DDR II3	DDR II4
2 memory modules	DS/SS	- -	DS/SS	- -

1-5 Installation of Expansion Cards

You can install your expansion card by following the steps outlined below:

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.

For example: Installing a PCI Express x16 VGA card:

Please carefully pull out the small whitedrawable bar at the end of the PCI Express x16 slot when you try to install/ uninstall the VGA card. Please align the VGA card to the onboard PCI Express x16 slot and press firmly down on the slot. Make sure your VGA card is locked by the small white-drawable bar.

To release an installed card, users can also press the latch on the opposite side of the drawable bar as the picture to the left shows.

1/2) ATX_12V / ATX (Power Connector)

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.

3/4) CPU_FAN / SYS_FAN (Cooler Fan Power Connector)

The cooler fan power connector supplies a +12V power voltage via a 3-pin/4-pin(CPU_FAN) power connector and possesses a foolproof connection design.

Most coolers are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V power voltage. The black connector wire is the ground wire (GND).

Remember to connect the CPU/system fan cable to the CPU_FAN/SYS_FAN connector to prevent CPU damage or system hanging caused by overheating.
