Installation Guide

Installation Guide

Getting Started

WARNING!

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 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 slo ts 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.

Memory Installation

The motherboard has 3 dual inline memory mod ule (DIM M) sock ets supp ort 4 banks. The BIOS
will automatically 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 two notch.
Memory size can vary between sockets.

SDRAM

1. The DIMM slot has two notch, so the DIMM
memory module can only fit in one direction.

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.

Install memory in any combination table:

@BIOS™ Introduction

Gigabyte announces
Windows BIOS live update utility

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

Windows overdrive utilit y

“Overdrive” might be one of the most
common issues in computer field. But have
many users ever tried it? The answer is
probably “no”. Because “overdrive” is thought to
be very difficult and includes a lot of technical
know-how, sometimes “overdrive” is even
considered as special skills found only in some
enthusiasts.

But as to the experts in “overdrive”, what’s the truth? They may spend quite a lot
of time and money to study, try and use many different hardware and software tools
to do “overdrive”. And even with these technologies, they still learn that it’s quite a
risk because the safety and stability of an “overdrive“ system is unknown.

Now everything is different because of a Windows overdrive utility
EasyTune

rule of “overdrive”. This is the first overdrive utility suitable for both normal and power
users. Users can choose either “Easy Mode” or “Advanced Mode” to run “overdrive”
at their convenience. For users who choose “Easy Mode”, they just need to click
“Auto Optimize” to have auto and immediate CPU overclocking. This software will
then overdrive CPU speed automatically with the result being shown in the control
panel. If someone prefers to “overdrive” by oneself, there is also another choice.
Click “Advanced Mode” to enjoy “sport drive” class overclocking. In “Advanced
Mode”, one can change the system bus speed in small increments to get ultimate
system performance. And no matter which mainboard is used, if it’s a Gigabyte’s

product*, EasyTune

Besides, different from other traditional over-clocking methods, EasyTune
doesn’t require users to change neither BIOS nor hardware switch/ jumper setting;
on the other hand, they can do “overdrive” at only one click. Therefore, this is a safer
way for “overdrive” as nothing is changed on software or hardware. If user runs

BIOS Setup

BIOS Setup is an overview of the BIOS Setup Program. The program that allows users to
modify the basic system configuration. This type of information is stored in battery-backed
CMOS RAM so that it retains the Setup information when the power is turned off.

ENTERING SETUP

Power ON the computer and press <Del> immediately will allow you to enter Setup. If the
message disappears before you respond and you still wish to enter Setup, restart the system to
try again by turning it OFF then ON or pressing the "RESET" bottom on the system case. You
may also restart by simultaneously press <Ctrl> − <Alt>− <Del> keys.

If it is set to enable, the category will flash on the screen when there is any attempt to write
to the boot sector or partition table of the hard disk drive. The system will halt and the
following error message will appear in the mean time. You can run anti-virus program to
locate the problem.

Enabled Activate automatically when the system boots up causing a warning

message to appear when anything attempts to access the boot sector or
hard disk partition table

Disabled No warning message to appear when anything attempts to access the

boot sector or hard disk partition table.

Memory

••••

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

(Default Value)

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 systems 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

Other 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.

This refers to the memory located in the 640 K to 1024 K address space. This is
memory that can be used for different applications.

DOS uses this area to load device drivers to keep as much base memory free
for application programs. Most use for this area is Shadow RAM.
