Gigabyte GA 7VAC 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(1.5V) notch"(show below), please make sure yourAGP

card is AGP 4X(1.5V).

AGP4Xnotch

Caution:AGP 2X(3.3V) card is not supported by VIA^®KT333CF. You

might experience system unable to boot up normally. Please insert

an AGP 4X(1.5V) card

Example 1: Diamond Vipper V770 golden finger is compatible with

2X/4X mode AGP slot. It can be switched betweenAGP 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-C (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: SomeATi 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-C (or any AGP 4X only)

motherboards might not function properly, If you install this

card in it.

Note :Although Gigabyte'sAG32S(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^®KT333CF based motherboards.

DDR Introduction

Established on the existing SDRAM industryinfrastructure, DDR (Double Data Rate) memory is a

high performanceandcost-effectivesolutionthatallows easyadoptionformemoryvendors, OEMs and

systemintegrators.

DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing

SDRAMinfrastructure,yetmakesawesomeadvances in solving thesystem performancebottleneckby

doubling the memory bandwidth. DDRSDRAM 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 thedatarate throughreadingand writingatboththerisingandfallingedgeof

theclock, achieving data bandwidth 2X greaterthanPC133when running with the same DRAM clock

frequency.With peak bandwidth of2.664GBpersecond, DDR memoryenables systemOEMs tobuild

high performance and lowlatencyDRAM subsystems thatare 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, DDRmemoryis a compelling solutionfor small form factor desktops

andnotebookapplications.

Step 3: Install expansion cards

1. Readtherelatedexpansioncard’sinstructiondocumentbeforeinstallthe expansion cardinto

thecomputer.

2. Remove your computer’s chassiscover, necessaryscrews and slotbracketfrom thecomputer.

3. Press the expansion card firmlyintoexpansion slotinmotherboard.

4. Besure the metalcontactsonthe cardareindeedseated in the slot.

5. Replacethescrew tosecure the slotbracketoftheexpansion card.

6. Replaceyour computer’schassis cover.

7. Power on the computer, ifnecessary, setup BIOS utilityof expansion cardfrom BIOS.

8. Install related driver from theoperating system.

Pleasecarefullypull out the small white-

Memory

The category is display-only which is determined by POST (Power On Self Test) of the BIOS.

Base Memory

The POST of the BIOS will determine the amount of base (or conventional) memory

installed in the system.

The value of the base memory is typically 512 K for sy stems with 512 K memory

installed on the motherboard, or 640 K for systems with 640 K or more memory

installed on the motherboard.

Extended Memory

The BIOS determines how much extended memory is present during the POST.

This is the amount of memory located above 1 MB in the CPU’s memory

address map.

@ BIOS Introduction

Gigabyte announces @ BIOS

Windows BIOS live update utility

Have you ever updated BIOS by yourself? Or like

many other people, you just know what BIOS is,

but always hesitate to update it? Because you

think updating newest BIOS is unnecessary and

actually you don’t know how to update it.

Maybe not like others, you are very experienced in BIOS updating and spend quite a lot of

time to do it. But of course you don’t like to do it too much. First, download different BIOS from

website and then switch the operating system to DOS mode. Secondly, use different flash utility to

update BIOS. The above process is not a interesting job. Besides, always be carefully to store the

BIOS source code correctly in your disks as if you update the wrong BIOS, it will be a nightmare.

Certainly, you wonderwhy motherboard vendors could not just do something right to save

your time and effort and save you from the lousy BIOS updating work? Here it comes! Now

Gigabyte announces @BIOS— the first Windows BIOS live update utility. This is a smart BIOS

update software. It could help you to download the BIOS from internetand update it. Not like the

other BIOS update software, it’s a Windows utility. With the help of “@BIOS’, BIOS updating is no

more than a click.

Besides, no matter which mainboard you are using, if it’s a Gigabyte’s product*, @BIOS help

you to maintain the BIOS. This utility could detect your correct mainboard model and help you to

choose the BIOS accordingly. It then downloads the BIOS from the nearest Gigabyte ftp site

automatically. There are several different choices; you could use “Internet Update” to download

and update your BIOS directly. Or you may want to keep a backup for your current BIOS, just

choose “Save Current BIOS” to save it first. You make a wise choice to use Gigabyte, and @BIOS

update your BIOS smartly. You are now worryfree from updating wrong BIOS, and capable to

maintain and manage your BIOS easily. Again, Gigabyte’s innovative product erects a milestone

in mainboardindustries.

For such a wonderful software, how much it costs? Impossible! It’s free! Now, if you buy a

Gigabyte’s motherboard, you could find this amazing software in the attached driver CD. But

please remember, connected to internet at first, then you could have a internet BIOS update from

your Gigabyte @BIOS.

Easy Tune^TM4 Introduction

Gigabyte announces EasyTune^TM4 Windows based Overclocking utility

EasyTune 4 carries on the heritage so as to pave the way for future generations.

Overclock" might be one of the most common issues in computer field. But have many users ever

tried it? The answer is probably "no". Because

"Overclock" is thought to be very difficult and in-

cludes a lot of technical know-how, sometimes

"Overclock" is even considered as special skills

found only in some enthusiasts. But as to the ex-

perts in "Overclock", what's the truth? They may

spend quite a lot of time and money to study, try

and use many different hardware or BIOS tools to

do "Overclock". And even with these technologies,

theystill learn that it's quite a risk becausethe safety

and stability of an "Overclock" system is unknown. Now everything is different because of a Win-

dows based overclocking utility "EasyTune 4" --announced byGigabyte. This windows based utility

has totally changed the gaming rule of "Overclock". This is the first windows based overclocking

utility is suitable for both normal and power users. Users can choose either "Easy Mode" or "Ad-

vanced Mode" for overclocking attheir convenience. For users who choose "EasyMode", they just

need to click "Auto Optimize" to have autoed and immediate CPU overclocking. This software will

then overdrive CPU speed automatically with the result being shown in the control panel. If users

prefer "Overclock" by them, there is also another choice. Click "Advanced Mode" to enjoy "sport

drive" class Overclocking user interface. "Advanced Mode", allows users to change the system bus

/ AGP / Memory working frequency in small increments to getultimate system performance. It oper-

ates in coordination with Gigabyte motherboards. Besides, it is different from other traditional over-

clocking methods, EasyTune 4 doesn'trequire users to change neither BIOS nor hardware switch/

jumper setting; on the other hand, they can do "Overclock" at easy step . Therefore, this is a safer

way for "Overclock" as nothing is changed on software or hardware. Ifuser runs EasyTune 4 over

system's limitation, the biggest lost is only to restart the computer again and the side effect is then

well controlled.Moreover, ifone well-performedsystem speed has been tested in EasyTune 4, user

can "Save" this setting and "Load" it in next time. Obviously, Gigabyte EasyTune 4 has already

turned the "Overclock" technology toward to a newer generation. This wonderful software is now

free bundled in Gigabyte motherboard attached in driver CD. Users may make a test drive of

"EasyTune 4" to find out more amazing features by themselves.

*Some Gigabyte products are not fully supported by EasyTune 4. Please find the products sup-

ported list in the web site.

*Any "Overclocking action" is at user's risk, Gigabyte Technology will not be responsible for any

damage orinstability to yourprocessor, motherboard, or anyother components.
