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 card is not supported by SiS® 655FX. 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-8S655FX Ultra/GA-8S655FX (-L)
(or any AGP 4X only) motherboardsmight 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-8S655FX Ultra/GA-8S655FX (-L)
(or any AGP 4X 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
SiS® 655FX 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.
Installing the motherboard to the chassis…
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.

Step 1-2 : CPU Cooling Fan Installation
Before installing the CPU Cooling Fan, adhere to the following warning:
1. Please use Intel approved cooling fan.
2. We recommend you to apply the thermal tape to provide better heat conduction
between your CPU and cooling fan.
(The CPU cooling fan might stick to the CPU due to the hardening of the thermal
paste. During this condition if you try to remove the cooling fan, you might pull the
processor out of the CPU socket alone with the cooling fan, and might damage the
processor. To avoid this from happening, we suggest you to either use thermal
tape instead of thermal paste, or remove the cooling fan with extreme caution.)
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.
1. Fasten the cooling fan supporting-base
onto the CPU socket on the
mainboard.
2. Make sure the CPU fan is plugged to
the CPU fan connector, than install

Step 2: 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 processor and heatsink, adhere to the following warning:
When RAM_LED is ON, do not install/remove DIMM from socket.
Please note that the DIMM module can only fit in one direction due to the one notches.
Wrong orientation will cause improper installation. Please change the insert orientation.

GA-8S655FX Ultra/GA-8S655FX(-L) supports the Dual Channel Tec hnology. After operating the Dual
Channel Technology, the bandwidth of M emory Bus will add double up to 6.4GB/s.
GA-8S655FX Ultra/GA-8S655FX(-L) includes 4 DIM M sockets, and each Channel has two DIMM sockets as
following:
Channel A : DIM M 1, DIM M 2
Channel B : DIMM 3, DIMM 4
If yo u want to operate the Dual Channel Technology, please note the following explanations due
to the l imitation of SiS® chipset specificati ons.
1. One/three DDR memory module is installed: The Dual Channel Technology can't operate
when only one or three DDR m emory module is installed.
- 14 -GA-8S655FX Series Motherboard
English
2. Two DDR m emory modules are installed (the same mem ory size and type): The Dual
Channel Technology will operate when two me mory modules are inserted in dividually into
Channel A and B. If you install two mem ory modules in the same channel, the Dual Channel
Techno logy will not operate. Additiona lly, you can boot the system only when one of the
mem ory modules is inserted into Channel A or Channel B. On the other hand, the memory
module must be inserted into any sockets.
3. Four DDR mem ory modules are installed: If you install four m emory modules at the same
time, the D ual Channel Technology will operate only when those modules have the same
mem ory size and type.
We'll strongly recommend our user to slot into two DDR memory modules into the DIMMs with the
same color in order for Dual Channel Technology to work.
The following table is for Dual Channel Technology combination:

@ BIOSTM 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 wonder why 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 worry free from updating wrong BIOS, and capable to maintain and
manage your BIOS easily. Again, Gigabyte's innovative product erects a milestone in mainboard
industries.
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 TuneTM 4 Introduction
Gigabyte announces EasyTune

Windows based Overclocking utility
EasyTune 4 carries on the heritage so as to pave the way for future generations.
ware or BIOS tools to do "Overclock". And even with these technologies, they still learn that it's quite a
risk because the safety and stability of an "Overclock" system is unknown. Now everything is different
because of a Windows based overclocking utility "EasyTune 4" --announced by Gigabyte. 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 "Advanced Mode" for overclocking at their convenience. For users who choose "Easy Mode", 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 get ultimate system performance. It operates in
coordination with Gigabyte motherboards. Besides, it is different from other traditional over-clocking
methods, EasyTune 4 doesn't require 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. If user 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, if one
well-performed system 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 supported list
in the web site.
*Any "Overclocking action" is at user's risk, Gigabyte Technology will not be responsible for any
damage or instability to your processor, motherboard, or any other components.
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 includes a lot of
technical know-how, sometimes "Overclock" is even
considered as special skills found only in some
enthusiasts. But as to the experts in "Overclock",
what's the truth? They may spend quite a lot of time
and money to study, try and use many different hard-

A. What is Dual BIOS Technology?
BIOS and the other is Backup BIOS. Under the normal circumstances, the system works on the
Main BIOS. If the Main BIOS is corrupted or damaged, the Backup BIOS can take over while the
system is powered on. This means that your PC will still be able to run stably as if nothing has
happened in your BIOS.
B. How to use Dual BIOS and Q-Flash Utility?
a. After power on the computer, pressing <Del> immediately during POST (Power On Self Test) it will
allow you to enter Award BIOS CMOS SETUP, then press <F8> to enter Flash utility.

DualBIOSTM Tec hnology FAQ
GIGABYTE Technology is pleased to introduce DualBIOS technology, a hot spare for your
system BIOS. This newest "Value-added" feature, in a long series of innovations from GIGABYTE,
is available on this motherboard. Future GIGABYTE motherboards will also incorporate this
innovation.
What’s DualBIOSTM?
On GIGABYTE motherboards with DualBIOS there are physically two BIOS chips. For
simplicity we’ll call one your "Main BIOS" and the other we'll call your "Backup" BIOS (your "hot
spare"). If your Main BIOS fails, the Backup BIOS almost automatically takes over on your next
system boot. Almost automatically and with virtually zero down time! Whether the problem is a
failure in flashing your BIOS or a virus or a catastrophic failure of the Main BIOS chip, the result is
the same - the Backup BIOS backs you up, almost automatically.
I. Q: What is DualBIOSTM technology?
Answer:
DualBIOS technology is a patented technology from Giga-Byte Technology. The concept of this
technology is based on the redundancy and fault tolerance theory. DualBIOSTM technology simply
means there are two system BIOSes (ROM) integrated onto the motherboard. One is a main BIOS,
and the other is a backup BIOS. The mainboard will operate normally with the main BIOS, however,
if the main BIOS is corrupt or damaged for various reasons, the backup BIOS will be automatically
used when the system powered-On. Your PC will operate as before the main BIOS was damaged,
and is completely transparent to the user.

Tech nical Reference
II. Q: Why does anyone need a motherboard with DualBIOSTM technology?
Answer:
English
attacks, BIOS upgrade failures, and/or deterioration of the BIOS (ROM) chip itself.
III. Q: How does DualBIOSTM technology work?
Answer:
In today's systems there are more and more BIOS failures. The most common reasons are virus
1. New computer viruses are being found that attack and destroy the system BIOS. They may
corrupt your BIOS code, causing your PC to be unstable or even not boot normally.
2. BIOS data will be corrupted if a power loss/surge occurs, or if a user resets the system, or if
the power button is pressed during the process of performing a system BIOS upgrade.
3. If a user mistakenly updates their mainboard with the incorrect BIOS file, then the system
may not be able to boot correctly. This may cause the PC system hang in operation or
during boot.
4. A flash ROM's life cycle is limited according to electronic characteristics. The modern PC
utilizes the Plug and Play BIOS, and is updated regularly. If a user changes peripherals
often, there is a slight chance of damage to the flash ROM.
With Giga-Byte Technology’s patented DualBIOSTM technology you can reduce the
possibility of hangs during system boot up, and/or loss BIOS data due to above reasons.
This new technology will eliminate valuable system down time and costly repair bills cause
by BIOS failures.
1. DualBIOSTM technology provides a wide range of protection during the boot up procedure. It
protects your BIOS during system POST, ESCD update, and even all the way to PNP
detection/assignment.
2. DualBIOSTM provides automatic recovery for the BIOS. When the first BIOS used during
boot up does not complete or if a BIOS checksum error occurs, boot-up is still possible. In
the DualBIOSTM utility, the "Auto Recovery" option will guarantee that if either the main
BIOS or backup BIOS is corrupted, the DualBIOSTM technology will use the good BIOS
and correct the wrong BIOS automatically.
3. DualBIOSTM provides manual recovery for the BIOS. DualBIOSTM technology contains a
built-in flash utility, which can flash your system BIOS from backup to main and/or visa
versa. There is no need for an OS-dependent flash utility program.
4. DualBIOSTM contains a one-way flash utility. The built-in one-way flash utility will ensure that
the corrupt BIOS is not mistaken as the good BIOS during recovery and that the correct
BIOS (main vs. backup) will be flashed. This will prevent the good BIOS from being
flashed.
- 72 -GA-8S655FX Series Motherboard
IV. Q: Who Needs DualBIOSTM technology?
Answer:
1. Every user should have DualBIOSTM technology due to the advancement of computer
viruses.
Everyday, there are new BIOS-type viruses discovered that will destroy your system
BIOS. Most commercial products on the market do not have solutions to guard against this
type of virus intrusion. The DualBIOSTM technology will provide a state-of-the-art solution to
protect your PC:
Case I.) Vicious computer viruses may wipe out your entire system BIOS. With a
conventional single system BIOS PC, the PC will not be functional until it is sent for repairs.
Case II.) If the "Auto Recovery" option is enabled in the DualBIOSTM utility, and if a virus
corrupts your system BIOS, the backup BIOS will automatically reboot the system and
correct the main BIOS.
Case III.) A user may override booting from the main system BIOS. The DualBIOSTM utility
may be entered to manually change the boot sequence to boot from the backup BIOS.
2. During or after a BIOS upgrade, if DualBIOSTM detects that the main BIOS is corrupt, the
backup BIOS will take over the boot-up process automatically. Moreover, it will verify the
main and backup BIOS checksums when booting-up. DualBIOSTM technology examines
the checksum of the main and backup BIOS while the system is powered on to guarantee
your BIOS operates properly.
3. Power Users will have the advantage of having two BIOS versions on their mainboard. The
benefit is being able to select either version BIOS to suit the performance system needs.
4. Flexibility for high-end desktop PCs and workstation/servers. In the DualBIOSTM utility,
the option can be set, "Halt On When BIOS Defects," to be enabled to halt your system with
awarning message that the main BIOS has been corrupted. Most workstation/servers
require constant operation to guarantee services have not been interrupted. In this situation,
the "Halt On When BIOS Defects" message may be disabled to avoid system pauses
during normal booting. Another advantage you gain from Giga-Byte's DualBIOS
technology is the ability to upgrade from dual 2 Mbit BIOS to dual 4
Mbit BIOS in the future if extra BIOS storage is need.
