1-3Installation 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.

(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
heats ink to the CPU fan head er l ocate d 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.

1-4Installation of Memory
English
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.
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 II
GA-8I915P-D Pro supports the Dual Channel Technology. After operating the
Dual Channel Technology, the bandwidth of Memory Bus will add double up to
8.5GB/s.
GA-8I915P-D Pro includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DDR II 1, DDR II 2
Channel B : DDR II 3, DDR II 4
If you want to operate the Dual Channel Technology, please note the following explanations due
to the limitation of Intel chipset specifications.
1. One/three DDR II memory module is installed: The Dual Channel Technology can't operate
when only one DDR II memory module is installed.
2. Two 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. If you install two memory modules in the same channel, the Dual Channel
Technology will not operate.
3. Four DDR II memory modules are installed: If you install four memory modules at the same
time, the Dual Channel Technology will operate only when those modules have the same
memory size and type.
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 table is for Dual Channel Technology combination: (DS: Double Side, SS: Single Side)

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.
Please remove the sticker on the motherboard before plugging in while the ATX power supplier is 24
pins; Otherwise, please do not remove it.

The cooler fan power connector supplies a +12V power voltage via a 3-pin/4-pin (only for 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).
Please remember to connect the power to the cooler to prevent system overheating and failure.
