Gigabyte GA-7VA1004 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).

AGP 4X/8X notch

Caution: AGP 2X(3.3V) card is not supported by VIA® KT400. 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-7VA (or any AGP 4X only) motherboards might not function

properly, if you install this card without switching the jumper to 4X(1.5) 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-7VA (or any AGP 4X only)

motherboards might not function properly, If you install this card in it.

Note : Although Gigaby te'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 VIA® KT400 based motherboards.

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.

WARNING!

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.

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.

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.

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 w ill 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 v alue des ktop SM A sy stems. 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.

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, necessary 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.

English

AGP Card

Please carefully pull out the small whitedrawable 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 white- drawable bar.
