1-3 Installation of the CPU and Heatsink

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

1-3-2 Installation of the Heatsink

Male Push Pin

The top of Female Push Pin

Female Push Pin

Fig.1

Please apply an even layer of heatsink paste on the surface of the installed CPU.

Fig. 3

Place the heatsink 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 heatsink, 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 heatsink installation section of the user manual)

Fig. 6

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

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

DDR

Notch

DDR II

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 DDR/DDR II

GA-8I915P Duo supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will add double.

GA-8I915P Duo includes 4	DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DDR 1	or	Channel A : DDR II 1
Channel B : DDR 2		Channel B : DDR II 2

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

1.If one DDR/DDRII memory modules are installed: The Dual Channel Technolog cannot operate when one DDR/DDRII memory modules are installed.

2.Two DDR/DDR II memory modules are installed (the same memory size and type): The Dual Channel Technology will operate when two memory modules are inserted individually into Channel A and B.

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

The following table is for Dual Channel Technology combination: (DS: Double Side, SS: Single Side)

	DDR 1	DDR 2
2 memory modules	DS/SS	DS/SS
OR
	DDR II 1	DDR II 2
2 memory modules	DS/SS	DS/SS

Note:Mixed mode, populating DDR and DDR II memory modules simultaneously is not supported.

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.
