Gigabyte GA-7VAX-A 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(3.3V) card is not supported by VIA

®

KT400A. You

might experience system unable to boot up normally. Please insert

an AGP 4X/8X(1.5V) 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-7VAX-A / GA-7VAX1394-A / GA-7VAXP-A / GA-7VAXP-A Ultra

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-7VAX-A / GA-7VAX1394-A / GA-7VAXP-A / GA-7VAXP-A Ultra

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 w ith VIA

®

KT400A based motherboards.

Before you install PCI cards, please remove the Dual BIOS

label from PCI slots if there is one.

Item Checklist

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

Power connector on the m otherboard.

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.

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.

Step1-2: CPU Installation

CPU Top View CPU Bottom View

Socket Actuation Lever

1. Pull up the CPU socket lever

and up to 90-degree angle.

Pin1 indicator

2. Locate Pin 1 in the socket and look

for a (golden) cut edge on the CPU

upper corner. Then insert the CPU

into the socket.

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.

Step1-3:CPU Cooling Fan Installation

3. Fasten the cooling fan supporting-base

onto the CPU socket on the main-

board.

2. Use qualified fan approved by AMD.

4. Make sure the CPU fan is

plugged to the CPU fan connector,

than install complete.

1. Press down the CPU socket

lever and finish CPU installation.

1. Please use AMD approved cooling fan.

2. We recommend you to apply the thermal paste 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.

Before installing the CPU Heat Sink , adhere to the following warning:

Notch

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 3 dual inline memory module(DIMM) sockets. The BIOS will automati-

cally 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.

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 m emory 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 m igration 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 band-

width of 2.664GB per second, DDR memory enables system OEM s to build high perform ance and low

latency DRAM subsystems that are suitable for servers, workstations, high-end PC's and value desktop SMA

systems. With a core voltage of only 2.5 volts compared to conventional SDRAM's 3.3 volts, DDR memory is

a compelling solution for small form factor desktops and notebook applications.

1. The DIMM slot has a notch, so the DIMM

memory module can only fit in one direction.

2. Insert the DIMM memory module vertically into

the DIMM slot. Then push it down.

3. Close the plastic clip at both edges of the DIMM

slots to lock the DIMM module.

Reverse the installation steps when you wish

to remove the DIMM module.
