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

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 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-945GME-DS2 supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of memory bus will double.
The GA-945GME-DS2 includes 2 DIMM sockets.
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 memory modules (it is recommended to use memory modules of identical brand, size, chips, and speed), you must install them into DDRII1 and DDRII2 memory sockets.

1-5 Installation of Expansion Cards
To install your expansion card, follow the steps below.
1.Disconnect your system from its power source and read the expansion card's installation manual before installing the expansion card in the computer.
2.Remove your computer's chassis cover, screws and slot bracket from the computer. Ground yourself to prevent damage to your computer resulting from Electrostatic discharge (ESD).
3.Press the expansion card firmly into the expansion slot in the motherboard.
4.Make sure the metal contacts on the card are fully 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, configure required settings for the expansion card in system BIOS Setup.
8.Install related driver in the operating system.
For example: Installing a PCI Express x16 VGA card:
When installing the graphics card, push down on the top edge of the card until it is fully inserted into the PCI Express x16 slot. Make sure the card is securely seated in the slot
and does not rock.
When removing the graphics card, gently push back on the black lever on the slot and then lift the card straight out from the slot.

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 power supply that provides a 24-pin ATX power connector, 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.

6)IDE (IDE Connector)
An IDE device connects to the computer via an IDE connector. One IDE connector can connect to one IDE cable, and the single IDE cable can then connect to two IDE devices (hard drive or optical drive). If you wish to connect two IDE devices, please set the jumper on one IDE device as Master and the other as Slave (for information on settings, please refer to the instructions located on the IDE device). Before attaching the IDE cable, please take note of the foolproof groove in the IDE connector.

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.
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. (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.)
3.Re-install the battery.
4.Plug the power cord in and turn on the computer.
