GIGABYTE GA-8IG1000MF User Manual

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-8IG1000MF 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 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-8IG1000MF 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.

Motherboard Settings Label

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 A TX power supply is switched of f before you plug in or remove the A TX 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 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.

Step 1-2: CPU Cooling Fan Installation

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.

2. Make sure the CPU fan is plugged
to the CPU fan connector, than

Before installing the memory modules, adhere to the following warning:

1.When RAM_LED is ON, do not install / remove DIMM from socket.

2.Please note that the DIMM module can only fit in one direction due to
the one notch. Wrong orientation will cause improper installation.
Please change the insert orientation.

Step 2: Install Memory Modules

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.

DDR

Notch

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 sockets
to lock the DIMM module.
Reverse the installation steps when you wish to remove
the DIMM module.

Below are the explanations:
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. Additionally, you can boot the
system only when the memory module is inserted into Channel A. On the other hand,
the memory module must be inserted into DIMM1 or DIMM3 sockets.

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. Additionally, you can boot the system only when
one of the memory modules is inserted into Channel A. On the other hand, the memory
module must be inserted into DIMM1 or DIMM3 sockets.

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.

Dual Channel DDR:

GA-8IG1000MF Series supports Dual Channel Technology.
When Dual Channel Technology is activated, the bandwidth of memory bus will be double the original
one,with the fastest speed at 6.4GB/s DDR400.
GA-8IG1000MF Series includes four DIMM slots, and each Channel has 2 DIMMs as following:

Channel A : DIMM 1, 2
Channel B : DIMM 3, 4

DDR Introduction

Established on the existing SDRAM industry 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 sensible evolutionary solution for the PC industry that builds on the existing
SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck
by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from
existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR
memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge
of the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM
clock frequency. With peak bandwidth of 2.664GB per second, DDR memory enables system OEMs
to build high performance and low latency DRAM subsystems that are suitable for servers, workstations,
high-end PC's and value desktop SMA systems.

When an AGP 2X (3.3V) card is installed the 2X_DET will light up, indicating a non-supported
graphics card is inserted. Informing users that system might not boot up normally due to
AGP 2X (3.3V) is not supported by the chipset.

Step 3: Install expansion cards

1. Read the related expansion card's instruction document before install the expansion card into the
computer.

2. Remove your computer's chassis cover, screws and slot bracket from the computer.

3. Press the expansion card firmly into expansion slot in motherboard.

4. Be sure the metal contacts on the card are indeed seated in the slot.

5. Replace the screw to secure the slot bracket of the expansion card.

6. Replace your computer's chassis cover.
