1-3 Installation of the CPU and Heatsink

Before installing the CPU, please comply with the following conditions:

1. Please make sure that the motherboard supports the CPU.

English

2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong

direction, the CPU will not insert properly. If this occurs, please change the insert direction

of the CPU.

3. Please add an even layer of heat sink paste between the CPU and heatsink.

4. Please make sure the heatsink is installed on the CPU prior to system use, otherwise

overheating and permanent damage of the CPU may occur.

5. Please set the CPU host frequency in accordance with the processor specifications. It is not

recommended that the system bus frequency be set beyond hardware specifications since it

does not meet the required standards for the peripherals. If you wish to set the frequency

beyond the proper specifications, please do so according to your hardware specifications

including the CPU, graphics card, memory, hard drive, etc.

1-4 Installation of Memory

Before installing the memory modules, please comply with the following conditions:

1. Please make sure that the memory used is supported by the motherboard. It is

English

recommended that memory of similar capacity, specifications and brand be used.

2. Before installing or removing memory modules, please make sure that the computer

power is switched off to prevent hardware damage.

3. Memory modules have a foolproof insertion design. A memory module can be installed

in only one direction. If you are unable to insert the module, please switch the direction.

The motherboard supports DDR memory modules, whereby BIOS will automatically detect memory

capacity and specifications. Memory modules are designed so that they can be inserted only in one

direction. The memory capacity used can differ with each slot.

Notch

DDR

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 the DIMM

slots to lock the DIMM module.

Reverse the installation steps when you wish

to remove the DIMM module.

Dual Channel DDR

English

GA-8I915ME-GV/GA-8I915ME-GL/GA-8I915ME-C/GA-8I915ME-G supports the Dual Channel

Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will add

double.

GA-8I915ME-GV/GA-8I915ME-GL/GA-8I915ME-C/GA-8I915ME-G includes 2 DIMM sockets, and each

Channel has two DIMM sockets as following:

Channel A : DIMM1

Channel B : DIMM2

If you want to operate the Dual Channel Technology, please note the following explanations due

to the limitation of Intel chipset specifications.

1. If one DDR memory modules are installed: The Dual Channel Technolog cannot operate when

one DDR memory modules are installed.

2. If two DDR memory modules are installed, please use memory of the same storage capacity

in order to use dual channel memory and for BIOS to detect all the DDR memory modules.

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.

1-5 Installation of Expansion Cards

You can install your expansion card by following the steps outlined below:

1. Read the related expansion card's instruction document before install the expansion card into the

English

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.

Installing a PCI Express x 16/G.E.A.R. expansion card:

Please carefully pull out the small white-

drawable bar at the end of the

PCI Express x 16/G.E.A.R. slot when

you try to install/Uninstall the VGA card.

Please align the VGA card to the onboard

PCI Express x 16/G.E.A.R. slot and press

firmly down on the slot .Make sure your

VGA card is locked by the small white-

drawable bar.

GA-8I915ME Series Motherboard - 16 -

English

1-5-1 What is G.E.A.R.?

The revolutionary and innovative G.E.A.R. (GIGABYTE Enhance AGP Riser) interface provides an

additional interface for traditional AGP Graphics card on Intel chipset based PCI Express solution

motherboard. It supports most of the AGP Graphics card available in the market from AGP 4X to AGP

8X graphics card.

Note:

1. Please remove the sticker on the G.E.A.R. slot before inserting your AGP graphics card.

2. G.E.A.R. interface is designed to provide a temporary AGP solution before the mass availability of

PCI Express graphics card. It is suggested to use PCI Express X 16 interface graphics card to avoid

the damage of your AGP graphics card.

3. G.E.A.R. interface is created through PCI interface signal and voltage switching to AGP interface,

due to this technical specification difference, it might cause AGP graphics card life-span shortens.

4. Please view the graphics cards support list currently validated by GIGABYTE enginneers. For more

updated information, please logon to GIGABYTE website at http://www.gigabyte.com.tw

1/2) ATX_12V/ATX (Power Connector)

With the use of the power connector, the power supply can supply enough stable power to all the

components on the motherboard. Before connecting the power connector, please make sure that all

components and devices are properly installed. Align the power connector with its proper location on

English

the motherboard and connect tightly.

The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V power

connector is not connected, the system will not start.

Caution!

Please use a power supply that is able to handle the system voltage requirements. It is

recommended that a power supply that can withstand high power consumption be used (300W or

greater). If a power supply is used that does not provide the required power, the result can lead to an

unstable system or a system that is unable to start.

If you use a 24-pin ATX power supply, please remove the small cover on the power connector

on the motherboard before plugging in the power cord ; Otherwise, please do not remove it.
