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).
Caution: AGP 2X card is not supported by Intel® 845(GE/PE) / 845(E/G)
/ 850(E) / E7205 / 865(G/PE/P) / 875P. You might experience system
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-8IG1000 Series (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 AT i 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-8IG1000 Series (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) /
845(E/G) / 850(E) / E7205 / 865(G/PE/P) / 875P based motherboards.
Before you install PCI cards, please remove the Dual BIOS label from PCI
slots if there is one.

Warning
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.
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
ower connector on the motherboard.
If the motherboard has mounting holes, but they don't line up with the holes on the base and there
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.

Due to chipset (Intel 875P/865G/865PE) architecture limitation, a FSB 800 Pentium 4 processor
will support DDR400/DDR333/DDR266 memory module. A FSB 533 Pentium 4 processor will
support DDR333 and DDR266 memory module. A FSB 400 Pentium 4 processor will only support
DDR 266 memory module.
(Note 1) Due to standard PC architecture, a certain amount of memory is reserved for system usage and
therefore the actual memory size is less than the stated amount. For example, 4 GB of memory size
will instead be shown as 3.xxGB memory during system startup.

Please set the CPU host frequency in accordance with your processor's specifications.
We don't recommend you to set the system bus frequency over the CPU's specification
because these specific bus frequencies are not the standard specifications for CPU, chipset
and most of the peripherals. Whether your system can run under these specific bus
frequencies properly will depend on your hardware configurations, including CPU, Chipsets,
Memory, Cards...etc.

Before installing the processor, adhere to the following warning:
1.Please make sure the CPU type is supported by the motherboard.
2.If you do not match the CPU socket Pin 1 and CPU cut edge well, it will
cause improper installation. Please change the insert orientation.

Step 1-2 : CPU Cooling Fan Installation
2. Make sure the CPU fan is plugged to
the CPU fan connector, than install
completely.
1. Fasten the cooling fan supportingbase onto the CPU socket on the
motherboard.
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.

The motherboard has 4 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the DIMM
socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.
Step 2: Install Memory Modules
DDR
Notch
GA-8IG1000 Series supports the Dual Channel Technology. After operating the Dual Channel Technology ,
the bandwidth of Memory Bus will add double up to 6.4GB/s.
GA-8IG1000 Series includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DIMM 1, DIMM 2
Channel B : DIMM 3, DIMM 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.
Before installing the memory modules, adhere to the following warning:
1.Please note that the DIMM memory module can only fit in one direction
due to the notch. Wrong orientation will cause improper installation.
Please change the insert orientation.

2. Two DDR 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. Three DDR memory modules are installed: Please note that The Dual Channel Technology
will not operate when three DDR memory modules are installed; part of them will not be detected.
4. Four DDR 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 memory modules into the DIMMs with the
same color in order for Dual Channel Technology to work.

1. The DIMM socket has a notch, so the DIMM
memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into
the DIMM socket. Then push it down.
3. Close the plastic clip at both edges of the DIMM
slots to lock the DIMM memory module.
Reverse the installation steps when you wish
to remove the DIMM memory module.
DDR Introduction
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.

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.
AGP Card
Please carefully pull out the small white- drawable bar
at the end of the AGP slot when you try to install/
