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

Push Pin
Direction of
the Arrow Sign
on the Male
Push Pin
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.)
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-EP35-DS3R/DS3 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: DDRII1, DDRII2
Channel 1: DDRII3, DDRII4
Two Modules
Four Modules
DDRII1 DDRII2 DDRII3 DDRII4

DS/SS DS/SS DS/SS DS/SS
DualChannelMemoryConfigurationsTable
(SS=Single-Sided, DS=Double-Sided, "- -"=No Memory)
DDRII1 DDRII2 DDRII3 DDRII4
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.
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.

1-4-2 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.
