Gigabyte GA-8IEML-T 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 notch"(show below), please make sure your AGP card is
AGP 4X (1.5V).
Do not use AGP 2X card (3.3V) in this motherboard. It will burn
and damage the motherboard due to Intel®845(E/G) / 850(E)
chipset can't support AGP 2X(3.3V).
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). If you install this card in GA-8IEML-T(-C) (or any AGP 4X
only) motherboards without switching the jumper to 4X mode (1.5V), it
will burn the motherboard.
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/4X mode AGP slot, but they support
2X(3.3V) only. If you install this card in GA-8IEML-T(-C) (or any AGP 4X
only) motherboards, it will burn the motherboard.
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 Intel®845(E/G)
/ 850(E) based motherboards.

GA-8IEML-T Series Motherboard
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
othercomponents.
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 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,DDR, SDRAM,Cards….etc.

Please make sure the CPU type is supported by the motherboard.
Pin1 indicator Pin1indicator
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 edge on the CPU
upper corner. Then insert the CPU
into the socket.
3. Press down the CPU socket lever and
finish CPU installation.


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.

Step 1-2: CPU Heat Sink Installation
1. Fastentheheatsinksupporting-base

board.
2. Make sure the CPU fan is plugged
to the CPU fan connector, than
install complete.


Please use Intel approved cooling fan.


We recommend you to apply the thermal tape to provide better heat
conduction between your CPU and heatsink.
(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.)


Make sure the CPU fan power cable is plugged in to the CPU fan connector,
this completes the installation.


Please refer to CPU heat sink user’s manual for more detail installation
procedure.

Hardware Installation Process
Step 2: Install memory modules
The motherboard has 2 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 Slot.
The DIMM module can only fit in one direction due to the notch. Memory size can vary between
sockets.
1. The DIMM slot has a notch, so the DIMM
memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the
DIMM slot. Then push it down.
3. Close the plastic clip at both edges of theDIMM slots
to lock the DIMM module.
Reverse the installation steps when you wish to
remove the DIMM module.
Please note that the DIMM module can only fit in one direction due to the two
notches. Wrong orientation will cause improper installation. Please change
the insert orientation.
DDR
Support Unbuffered DDR DIMM Sizes type:
64 Mbit (2Mx8x4 banks) 64 Mbit (1Mx16x4 banks) 128 Mbit(4Mx8x4 banks)
128 Mbit(2Mx16x4 banks) 256 Mbit(8Mx8x4 banks) 256 Mbit(4Mx16x4 banks)
512 Mbit(16Mx8x4 banks) 512 Mbit(8Mx16x4 banks)
Notes: Double-sided x16 DDR memory devices are not support by Intel 845E/G chipset.

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, 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.
AGP Card
Please carefully pull out the small white-
drawable 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.
