When you installing AGP card, please make sure the following
notice is fully understood and practiced. If your AGP card has
"AGP 4X/8X (1.5V) notch"(show below), please make sure your
AGP card is AGP 4X/8X (1.5V).
AGP 4X/8X notch
Caution: AGP 2X card is not supported by Intel® 845(GE/PE) / 845(E/
G) / 850(E) / E7205 / 865(G/PE/PL/P) / 875P / 848P. You might
experiencesystem unable to boot up normally. Please insert an AGP
4X/8X card.
Example 1: Diamond Vipper V770 golden finger is compatible with 2X/4X
mode AGP slot. It can be switched between AGP 2X(3.3V) or 4X(1.5V)
mode by adjusting the jumper. The factory default for this card is
2X(3.3V). The GA-8I865P(-G) (or any AGP 4X/8X only) motherboards
might not function properly, if you install this card without switching the
jumper to 4X(1.5V) mode in it.
Example 2: Some ATi Rage 128 Pro graphics cards made by "Power Color",
the graphics card manufacturer & some SiS 305 cards, their golden finger
is compatible with 2X(3.3V)/4X(1.5V) mode AGP slot, but they support 2X
(3.3V) only. The GA-8I865P(-G) (or any AGP 4X/8X only) motherboards
might not function properly, If you install this card in it.
Note: Although Gigabyte's AG32S(G) graphics card is based on ATi Rage
128 Pro chip, the design of AG32S(G) is compliance with AGP 4X(1.5V)
specification. Therefore, AG32S(G) will work fine with Intel® 845(GE/PE) /

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some precautions whenever you
work on your computer.
Installing the motherboard to the chassis…
are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the
mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so
be careful of your hands). In this way you can still attach the motherboard to the base without worrying
about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the
motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't let the
screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may
damage the board or cause board malfunctioning.
1.Unplug your computer when working on the inside.
2.Use a grounded wrist strap before handling computer components. If you do not have
one, touch both of your hands to a safely grounded object or to a metal object, such as
the power supply case.
3.Hold components by the edges and try not touch the IC chips, leads or connectors, or
other components.
4.Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.
5.Ensure that the ATX power supply is switched off before you plug in or remove the ATX
power connector on the motherboard.
If the motherboard has mounting holes, but they don't line up with the holes on the base and there

Step 1: Install the Central Processing Unit (CPU)
English
Step 1-1: CPU Installation
Before installing the processor, adhere to the following warning:
1. Please m ake sure that the motherboard supports the CPU.
2. Please take note of the one indented corne r of the CPU. If you i nstall the CPU in the wrong
direction, the CPU will not in sert properly. If this occurs, please change the insert direction of
the CPU.
3. Please add an even layer of hea t 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 fr equency in accordance with the processor specifications. It is not
recomm ended that the system bus frequency be set beyond hardwarespecifications since
it does not meet the required standards for the peripherals. If you wish to set the frequency
beyond the pr oper specifications, please do so according to your hardware specifications
including the CPU, graphics card, m emory, hard drive, etc.

Enabling the functionality of Hyper-Threading Technology for your comp uter system requires all
of the following pl atform compo nents:
- CPU: An In tel® Pentium® 4 Processor with HT Technology
- Chipset: An Intel® Chipset that supports HT Technology
- BIOS: A BIOS that supports HT Technology and has it en abled

Step 1-2 : CPU Cooling Fan Installation
Before installing the CPU cooling fan, adhere to the following warning:
1. Please use Intel approved cooling fan.
2. We recommend you to apply the thermal tape to provide better heat conduction
between your CPU and cooling fan.
(The CPU cooling fan might stick to the CPU due to the hardening of the thermal
paste. During this condition if you try to remove the cooling fan, you might pull the
processor out of the CPU socket alone with the cooling fan, and might damage the
processor. To avoid this from happening, we suggest you to either use thermal tape
instead of thermal paste, or remove the cooling fan with extreme caution.)
3. Make sure the CPU fan power cable is plugged in to the CPU fan connector, this
completes the installation.
Please refer to CPU cooling fan user's manual for more detail installation procedure.
English
1. Fasten the cooling fan supporting-base
onto the CPU socket on the
mainboard.
2. Make sure the CPU fan is plugged to
the CPU fan connector, than install

- 13 -Hardware Installation Process
Step 2: Install memory modules
English
The motherboard supports DDR 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.
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.

DDR
GA-8I865P(-G) supports the Dual Channel Technolo gy. After operati ng the Dual Channel Techno logy,
the bandwidth of Memor y Bus will add double up to 6.4GB/s.
GA-8I865P(-G) includes 4 DIM M sockets, and each Channel has two DIM M sockets as following:
Channel A : DIM M 1, DIMM 2
Channel B : DIMM 3, DIM M 4
If you want to operate the Dual Channel Technology, please note the following explanations due to
the limitation of Intel® chipset specifications.
1. Only one DDR memory module is installed: The Dual Channel Technology can't operate
when only one DDR memory module is installed.
- 14 -GA-8I865P(-G) Motherboard
2. Two DDR m emory modules are installed (the sam e memory size and type): The Dual
Channel Technology will operate when two me mory modules are inserted individually into
Channel A and B. If you install two mem ory modules in the same channel, the D ual Channel
Techn ology wil l not ope rate.
3. Three DDR mem ory modules are installe d: Please note that The Dual Channel
Technology will not operate when three DDR m emory modules are installed; part of
them will not be detected.
4. Four DDR mem ory modules are installed: If you install four memory modules at the same
time, the D ual Channel Technology will operate only when those m odules have the sam e
mem ory size and type.
We'll strongly recommend our user to slot two DDR memory modules into the DIMMs with the
same color in order for Dual Channel Technology to work.
The following tables include all memory-installed combination types:

Established on the existing SDRAM infrastructure, DDR (Double Data Rate) memory is a high
performance and cost-effective solution that allows easy adoption for memory vendors, OEMs,
and system integrators.
DDR memory is a great evolutionary solution for the PC industry that builds on the existing
SDRAM architecture, yet make the awesome advances in solving the system performance
bottleneck by doubling the memory bandwidth. Nowadays, with the highest bandwidth of 3.2GB/
s of DDR400 memory and complete line of DDR400/333/266/200 memory solutions, DDR memory
is the best choice for building high performance and low latency DRAM subsystem that are
suitable for servers, workstations, and full range of desktop PCs.

connector is not connected, the system will not start.
Caution!
Please use a power sup ply that is able to handle th e system voltag e requirements. It is
recomm ended that a power supply that can withstand high power consum ption be u sed (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.
