Gigabyte GA-8TRS300M 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 (1.5V).
AGP 4X/8X notch
Caution: AGP 2X card is not supported by ATi RS300(9100 IGP). 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-8TRS300M (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-GA-8TRS300M (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 ATi RS300(9100 IGP)
based motherboards.

Warning
English
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.
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.
If the motherboard has mounting holes, but they don't line up with the holes on the base and there

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, Memory, Cards… .etc.

software installation.
- 10 -GA-8TRS300M Motherboard
Step 1: Install the Central Processing Unit (CPU)
Before installing the processor, adhere to the following warning:
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.
Please make sure the CPU type is supported by the motherboard.
Step 1-1: CPU Installation
English
Angling the
rod to 65
1. Angling the rod to 65-degree maybe feel a
kind of tight , and then continue pull the rod

4. Locate Pin 1 in the socket and look
for a (golden) cut edge on the CPU
upper corner. Then insert the CPU
into the socket.

Step 1-2 : CPU Cooling Fan Installation
English
Before installing the CPU cool 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
complete.

Step 2: Install memory modules
Before installing the processor and heatsink, adhere to the following warning:
When DIMM_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.
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.

DDR
GA-8TRS300M supports the Dual Channel Tec hnology. After operating the Dual Channel Techn ology,
the bandwidth of Memor y Bus will add double up to 6.4GB/s.
GA-8TRS300M includes 4 DIMM 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 lim itation of ATi chipset specifica tions.
1. Only one DDR memory module is installed: The Dual Channel Technology can't operate
when only one DDR memory module is installed.
- 13 - Hardware Installation Process
English
We'll strongly recommend our user to slot two DDR memory modules into the DIMMs with the
same color in order for Dual Channel Technology to work.
The following tables include all memory-installed combination types:
(Please note that those types not in the tables will not boot up.)
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
Techn ology will not operate.
3. Three 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.
4. 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.

1. The DIMM slot has a notch, so the DIM M memory
module can only fit in one direction.
2. Insert the DIM M m emory module vertically into
the DIMM slot. Then push it down.
3. Close the plastic clip at both edges of the DIM M
slots to lock the DIMM module.
Reverse the installation steps when you wish
to remove the DIMM module.
DDR Introduction
English
Established on the existing SDRAM 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 great evolutionary solution for the PC industry that builds on the existing
SDRAM architecture, yet make the awesome advances in solving the system performance
bottleneck by doubling the memory bandwidth. Nowadays, with the highest bandwidth of 3.2GB/
s of DDR400 memory and complete line of DDR400/333/266/200 memory solutions, DDR memory
is the best choice for building high performance and low latency DRAM subsystem that are
suitable for servers, workstations, and full range of desktop PCs.
