Gigabyte 5225, 5222, 5230 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.

AGP 4X/8X notch

Caution: AGP 2X card is not supported by nVIDIA® nForce™ 2 400. You
might experience system unable to boot up normally. Please
insert an AGP Pro 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-7N400E(-L) (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-7N400E(-L) (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 nVIDIA® nForce2 400

based motherboards.

Before you install PCI cards, please remove the Dual BIOS label from PCI

slots if there is one.

Computer motherboards and expansion cards contain very delicate Integrated Circuit
(IC) chips. T o 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.

Installing the motherboard to the chassis...

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.

(*) If this "ATX_12V connector" is not connected, system cannot boot.

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, SDRAM, Cards…etc.

Step 2-2: CPU Cooling Fan Installation

English

Before installing the CPU cooling fan, adhere to the following warning:

1.Please use AMD approved cooling fan.

2.We recommend you to apply the thermal tape to provide better heat
conduction between your CPU and cooling fan.

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.

1. Press down the CPU socket lever
and finish CPU installation.

3. Fasten the cooling fan supporting-

base onto the CPU socket on the
motherboard.

7n400e_1001_q.p65 2003/7/17, ¤U¤È 02:5812

Step 3: Install Memory Modules

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

1. When DIMM 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.

The motherboard has 4
of 4 banks of DDR memory. DDR slot 1 uses 2 banks, DDR slot 2 uses 2 banks,DDR slot 3&4 share the
remaining 2 banks. Please refer to the following tables for possible memory configurations supported. The
BIOS will automatically detects memory type and size. To install the memory module, just push it
vertically into the DIMM Slot .The DIMM module can only fit in one direction due to the notch. Memory size
can vary between sockets.

The following tables include all memory-installed combination types:
(Please note that those types not in the tables will not boot up.)(DS: Double Side, SS: Single Side)

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

Step 4: 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.

7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.

8. Install related driver from the operating system.

Please carefully pull out the small white-drawable bar at the end of the AGP slot when you try
to install / uninstall the AGP card. Please align the AGP card to the onboard AGP slot and
press firmly down on the slot. Make sure your AGP card is locked by the small white­drawable bar.

English

When an AGP 2X (3.3V) card is installed the 2X_DETwill 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.
