Gigabyte GA-7VT880, GA-7VT880-L 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 VIA KT880. 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-7VT880 Pro / GA-7VT880-L / GA-7VT880 (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-7VT880 Pro / GA-7VT880-L / GA-7VT880 (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 VIA KT880 based
motherboards.

Before you install PCI cards, please remove the Dual BIOS label from PCI
slots if there is one.

The author assumes no responsibility for any errors or
omissions that may appear in this document nor does the
author make a commitment to update the information
contained herein.

Third-party brands and names are the property of their
respective owners.

Please do not remove any labels on motherboard, this may
void the warranty of this motherboard.

Due to rapid change in technology, some of the
specifications might be out of date before publication of
this booklet.

Installing the motherboard to the chassis...

no slots t o attach the spacers, do not become alarmed you can still attach t he spacers t o the mountin g
holes. Just cut the bottom portion of the spacers (the spacer may be a lit tle hard to cut off, so be carefu l of
your hands). In this way you can still attach the motherboard to the base without worrying about short
circuits. So metimes you may need to use the plastic springs to isolate the screw from the mother board
PCB surface, b ecause the circuit wire may be near by the hole. Be careful, don't let the screw contact
any pr inted circuit wr ite or parts on the PCB that are near the fixing hole , otherwise it may damage the
board or cause board malfunctioning.

Computer motherboards and expansion cards contain very delicate Integrated Circuit
(IC) chips. To protect them against damage from static electricity, you should fo llow
some precautions w henever you work on your computer.

1. Unplug your co mputer when working on the inside.

2. Use a grounde d wrist strap before handling computer components. If you do not have one, touch
both of yo ur hands to a safely gro unded object or to a metal object, such as the power supply
case.

3. Hold components by the edges and try no t touch the IC chips, leads or connectors, or other
compone nts.

4. Place compo nents on a grounded antistatic pad or on the bag that came with the components
whenever th e components are separa ted from t he system.

5. Ensure that the ATX power supply is switched off befor e you plug in or remove the ATX pow er
connector on the motherboard.

because these specific bus frequencies are not the standard specification s 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,
Chipse ts, SDRAM, Cards… etc.

Step 2: Install the Central Processing Unit (CPU)

English

Step 2-1: CPU Installation

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.

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 ed ge on the CPU
upper corner. Then insert the CPU
into the socket.

- 10 -GA-7 VT880 Serie Motherboard

Step 2-2: CPU Cooling Fan Installation

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.

English

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

3. Fasten the cooling fan supporting­base onto the CPU socket on the
motherboard.

2. Use qualified fan approved by AMD.

4. Make sure the CPU fan is plugged
to the CPU fan connector, than
install complete .

Hardwa re Installation Process

Step 3: Install Memory Modules

English

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.

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.

Notch

1. The DIMM socket has a notch, so the DIMM
memory mod ule 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 mo dule.
Reverse the installation steps when you wish to
remove the DIMM module.

DDR

- 12 -GA-7 VT880 Serie Motherboard

Dual Channel DDR:

GA-7 VT880 Pro / GA-7VT880-L / GA-7VT880 support 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-7 VT880 Pro / GA-7VT880-L / GA-7VT880 include 4 DIMM slots, and each Channel has 2 DIMMs
as following: Chann el A : DDR 1, 2

Below are the e xplanations:
If yo u want to operate the Dual Channel Technology, please note the following explanations due
to the limitation o f VIA 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.

2. Two DDR memory modules are installed: The Dual Channel Technology will operate
when two memory modules are inserted individually into Channel A and B and must use
the same memory frequency & memory size. If you install two memory modules in the
same channe l,the Dual Channel Technology will not operate.

The following tables include all memory-installed combination types:
(Ple ase note that this types not in the tables will not boot up.)

Step 4: Install expansion cards

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

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

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

4. Be sure the me tal 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, setu p BIOS utility of expansion card from BIOS.

8. Install related driver fro m the operating system.

English

Please care fully pull out the small white-drawable bar at the end of the AGP slot when you try
to install / uninsta ll 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 white­dra wable bar.
