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-7VAX/GA-7VAXP (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-7VAX/GA-7VAXP (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.
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. 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.
