Chapter 1 Hardware Installation
1-1 Installation Precautions
The motherboard contains numerous delicate electronic circuits and components which can
become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read
the user's manual and follow these procedures:
Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or•
warranty sticker provided by your dealer. These stickers are required for warranty validation.
Always remove the AC power by unplugging the power cord from the power outlet before•
installing or removing the motherboard or other hardware components.
When connecting hardware components to the internal connectors on the motherboard,•
make sure they are connected tightly and securely.
When handling the motherboard, avoid touching any metal leads or connectors.•
It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic com-•
ponents such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,
keepyourhandsdryandrsttouchametalobjecttoeliminatestaticelectricity.
Prior to installing the motherboard, please have it on top of an antistatic pad or within an•
electrostatic shielding container.
Before unplugging the power supply cable from the motherboard, make sure the power sup-•
ply has been turned off.
Before turning on the power, make sure the power supply voltage has been set according to•
the local voltage standard.
Before using the product, please verify that all cables and power connectors of your hard-•
ware components are connected.
To prevent damage to the motherboard, do not allow screws to come in contact with the•
motherboard circuit or its components.
Make sure there are no leftover screws or metal components placed on the motherboard or•
within the computer casing.
Do not place the computer system on an uneven surface• .
Do not place the computer system in a high-temperature environment.•
Turning on the computer power during the installation process can lead to damage to sys-•
tem components as well as physical harm to the user.
If you are uncertain about any installation steps or have a problem related to the use of the•
product,pleaseconsultacertiedcomputertechnician.

Read the following guidelines before you begin to install the CPU:
Make sure that the motherboard supports the CPU.•
(Go to GIGABYTE's website for the latest CPU support list.)
Always turn off the computer and unplug the power cord from the power outlet before installing•
the CPU to prevent hardware damage.
Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may•
locate the notches on both sides of the CPU and alignment keys on the CPU socket.)
Apply an even and thin layer of thermal grease on the surface of the CPU.•
Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and dam-•
age of the CPU may occur.

B. Follow the steps below to correctly install the CPU into the motherboard CPU socket.
Before installing the CPU, make sure to turn off the computer and unplug the power cord from
the power outlet to prevent damage to the CPU.
Step 1:
Completely raise the CPU socket lever.
Step 3:
Remove the protective socket cover from the
load plate. (To protect the CPU socket, always
replace the protective socket cover when the
CPU is not installed.)
Step 5:
Once the CPU is properly inserted, replace the
load plate and push the CPU socket lever back
into its locked position.
Step 2:
Lift the metal load plate from the CPU socket.
(DO NOT touch socket contacts.)
Step 4:
HoldtheCPUwithyourthumbandindexngers.
Align the CPU pin one marking (triangle) with the
pin one corner of the CPU socket (or you may
align the CPU notches with the socket alignment
keys) and gently insert the CPU into position.

1-3-2 Installing the CPU Cooler
Follow the steps below to correctly install the CPU cooler on the motherboard. (The following procedure uses
Intel®boxed cooler as the example cooler.)
Step 1:
Apply an even and thin layer of thermal grease
on the surface of the installed CPU.

Push Pin
Direction of the
Arrow Sign on

Pin
Step 2:
Before installing the cooler, note the direction of
the arrow sign on the male push pin. (Turn-
ing the push pin along the direction of arrow is to
remove the cooler, on the contrary, is to install.)
Step 3:
Place the cooler atop the CPU, aligning the four
push pins through the pin holes on the mother-
board. Push down on the push pins diagonally.
Step 4:
You should hear a "click" when pushing down
each push pin. Check that the Male and Female
push pins are joined closely. (Refer to your CPU
cooler installation manual for instructions on
installing the cooler.)
Step 5:
After the installation, check the back of the moth-
erboard. If the push pin is inserted as the picture
above shows, the installation is complete.
Step 6:
Finally, attach the power connector of the CPU
cooler to the CPU fan header (CPU_FAN) on the
motherboard.
Use extreme care when removing the CPU cooler because the thermal grease/tape between the
CPU cooler and CPU may adhere to the CPU. Inadequately removing the CPU cooler may damage
the CPU.

1-4 Installing the Memory
1-4-1 Dual Channel Memory Conguration
This motherboard provides two DDR3 memory sockets and supports Dual Channel Technology. After the
memoryisinstalled, theBIOSwillautomatically detectthespecicationsand capacityofthe memory. En-
abling Dual Channel memory mode will double the original memory bandwidth.
The two DDR3 memory sockets are divided into two channels and each channel has one memory socket as
following:
Channel 0: DDR3_1
Channel 1: DDR3_2
DDR3_1 DDR3_2
Read the following guidelines before you begin to install the memory:
Make sure that the motherboard supports the memory. It is recommended that memory of the•
same capacity, brand, speed, and chips be used.
(Go to GIGABYTE's website for the latest supported memory speeds and memory modules.)
Always turn off the computer and unplug the power cord from the power outlet before installing•
the memory to prevent hardware damage.
Memory modules have a foolproof design. A memory module can be installed in only one direc-•
tion. If you are unable to insert the memory, switch the direction.
Due to chipset limitations, read the following guidelines before installing the memory in Dual Channel mode.
Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.1.
When enabling Dual Channel mode with two memory modules, it is recommended that memory of2.
the same capacity, brand, speed, and chips be used for optimum performance.

Before installing a memory module, make sure to turn off the computer and unplug the power
cord from the power outlet to prevent damage to the memory module.
DDR3 and DDR2 DIMMs are not compatible to each other or DDR DIMMs. Be sure to install
DDR3 DIMMs on this motherboard.

install your memory modules in the memory sockets.
Step 1:
Note the orientation of the memory module. Spread the retaining
clips at both ends of the memory socket. Place the memory module
onthesocket.Asindicatedinthepictureontheleft,placeyourn-
gers on the top edge of the memory, push down on the memory and
insert it vertically into the memory socket.
Step 2:
The clips at both ends of the socket will snap into place when the
memory module is securely inserted.

1-5 Installing an Expansion Card
PCI Express x1 Slot
Follow the steps below to correctly install your expansion card in the expansion slot.
1. Locate an expansion slot that supports your card. Remove the metal slot cover from the chassis back panel.
2. Align the card with the slot, and press down on the card until it is fully seated in the slot.
3. Make sure the metal contacts on the card are completely inserted into the slot.
4. Secure the card's metal bracket to the chassis back panel with a screw.
5. After installing all expansion cards, replace the chassis cover(s).
6. Turn on your computer. If necessary, go to BIOS Setup to make any required BIOS changes for your
expansion card(s).
7. Install the driver provided with the expansion card in your operating system.
Example: Installing and Removing a PCI Express x16 Graphics Card:
•Installing a Graphics Card:
Gently push down on the top edge of the card until
it is fully inserted into the PCI Express slot. Make
sure the card is securely seated in the slot and
does not rock.
•Removing the Card:
Gently push back on the lever on the slot and then lift the card straight out from
the slot.
PCI Express x16 Slot
Read the following guidelines before you begin to install an expansion card:
•Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
•Always turn off the computer and unplug the power cord from the power outlet before installing
an expansion card to prevent hardware damage.
