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. (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
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 fre-
quency 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 alignment keys on the motherboard CPU socket and the notches on the CPU.

GA-EQ45M-S2 Motherboard - 14 -
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.
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
fingers. 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.
Step 2:
Before installing the cooler, note the direction
of the arrow sign on the male push pin.
(Turning the push pin along the direction of
arrow is to remove the cooler, on the contrary,
is to install.)
Male
Push Pin
Female
Push Pin
The Top

Push Pin
Direction of
the Arrow Sign
on the Male
Push Pin
Step 3:
Place the cooler atop the CPU, aligning the
four push pins through the pin holes on the
motherboard. Push down on the push pins
diagonally.
Step 4:
You should hear a "click" when pushing down each
pushpin. Checkthatthe Male andFemale push pins
are joined closely. (Refer to your CPU cooler instal-
lation manual for instructions on installing the cooler.)
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.
Step 5:
After the installation, check the back of the
motherboard. If the push pin is inserted as the
picture above, 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.

GA-EQ45M-S2 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.
When memory modules of different capacity and chips are installed, a message which says
memory is operating in Flex Memory Mode will appear during the POST. Intel®Flex Memory
Technology offers greater flexibility to upgrade by allowing different memory sizes to be
populated and remain in Dual Channel mode/performance.
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_2
Channel 1: DDR2_3, DDR2_4
Two Modules
Four Modules
DDR2_1 DDR2_2 DDR2_3 DDR2_4

DS/SS DS/SS DS/SS DS/SS
DualChannelMemoryConfigurationsTable
(SS=Single-Sided, DS=Double-Sided, "- -"=No Memory)
Due to chipset 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.
3. Before enabling Intel Management Engine, make sure DDR2_1 socket in Channel 0 is populated.
DDR2_1 DDR2_2 DDR2_3 DDR2_4

1-4-2 Installing a Memory
Notch
DDR2 DIMM
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.
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.
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.

GA-EQ45M-S2 Motherboard - 18 -
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 Graphics Card:
PCI Slot
PCI Express x16 Slot
PCI Express x1 Slot
•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.

•When removing the cable connected to a back panel connector, first remove the cable
from your device and then remove it from the motherboard.
•When removing the cable, pull it straight out from the connector. Do not rock it side to side
to prevent an electrical short inside the cable connector.
