Hardware Installation- 13 -
1-3 Installing the CPU and CPU Cooler
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.
•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
damage of the CPU may occur.
•Set the CPU host frequency in accordance with the CPU specifications. It is not recom-
mended that the system bus frequency be set beyond hardware specifications since it
does not meet the standard requirements for the peripherals. If you wish to set the frequency
beyond the standard specifications, please do so according to your hardware specifications
including the CPU, graphics card, memory, hard drive, etc.
1-3-1 Installing the CPU
A. Locate the pin one (denoted by a small triangle) of the CPU socket and the CPU.

A Small Triangle Mark
Denotes Pin One of the
Socket

GA-MA78GM-DS2H/S2HP/S2H Motherboard - 14 -
Step 2:
Align the CPU pin one (small triangle marking)
with the triangle mark on the CPU socket and
gently insert the CPU into the socket. Make
sure that the CPU pins fit perfectly into their
holes. Once the CPU is positioned into its
socket, place one finger down on the middle of
the CPU, lowering the locking lever and latch-
ing it into the fully locked position.
Step 1:
Completely lift up the CPU socket locking lever.
CPU Socket Locking
Lever
Do not force the CPU into the CPU socket. The CPU cannot fit in if oriented incorrectly. Adjust
the CPU orientation if this occurs.
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.

Hardware Installation- 15 -
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.
1-3-2 Installing the CPU Cooler
Follow the steps below to correctly install the CPU cooler on the CPU. (The following procedure uses
the GIGABYTE cooler as the example.)
Step 1:
Apply an even and thin layer of thermal grease
on the surface of the installed CPU.
Step 2:
Place the CPU cooler on the CPU.
Step 4:
Turn the cam handle from the left side to the
right side (as the picture above shows) to lock
into place. (Refer to your CPU cooler installa-
tion manual for instructions on installing the
cooler.)
Step 3:
Hook the CPU cooler clip to the mounting lug on
one side of the retention frame. On the other side,
push straight down on the the CPU cooler clip to
hook it to the mounting lug on the retention frame.
Step 5:
Finally, attach the power connector of the CPU
cooler to the CPU fan header (CPU_FAN) on
the motherboard.

GA-MA78GM-DS2H/S2HP/S2H Motherboard - 16 -
1-4 Installing the Memory
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 memory support list.)
•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
direction. If you are unable to insert the memory, switch the direction.
1-4-1 Dual Channel Memory Configuration
This motherboard provides four DDR2 memory sockets and supports Dual Channel
Technology. After the memory is installed, the BIOS will automatically detect the
specifications and capacity of the memory. Enabling Dual Channel memory mode
will double the original memory bandwidth.
The four DDR2 memory sockets are divided into two channels and each channel has two memory
sockets as following:
Channel 0: DDR2_1, DDR2_3
Channel 1: DDR2_2, DDR2_4
Due to CPU limitation, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that
memory of the same capacity, brand, speed, and chips be used and installed in the same
colored DDR2 sockets for optimum performance.

1-4-2 Installing a Memory
Notch
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.
DDR2 DIMMs are not compatible to DDR DIMMs. Be sure to install DDR2 DIMMs on
this motherboard.
DDR2 DIMM
A DDR2 memory module has a notch, so it can only fit in one direction. Follow the steps below to
correctly 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 fingers 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
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.
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 x16
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.
