1-3 Installation of the CPU and CPU Cooler
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the pin 1 marking (the small triangle) on 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 paste between the CPU and CPU cooler.
4. Please make sure the CPU cooler 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.
1-3-1 Installation of the CPU
Check the CPU pins to see that none are bent. Move the socket lever to the unlocked position as shown in Fig. 1 (90o to the plane of the motherboard) prior to inserting the CPU. The pin 1 location is designated on the CPU by a small triangle that corresponds to a triangle marking on the socket as shown in Fig.
2. Align the CPU to the socket and gently lower it into place. Do not force the CPU into the socket.
Fig.1
Socket Lever
Position lever at a 90 degree angle.
Fig.2 Pin 1 location on the socket and processor. Gently place the CPU into position making 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 and gently press the metal lever back into its original position.
Pin One
Please use extra care when installing the CPU. The CPU will not fit if positioned incorrectly. Rather than applying force, please change the positioning of the CPU.
GA-M55S-S3 Motherboard - 12 -
1-3-2 Installation of the CPU Cooler
Fig.1 Before installing the CPU cooler, please first add an even layer of heat paste on the surface of the CPU. Install all the CPU cooler components (Please refer to the cooler manual for detailed installation instructions).
Fig.2 Please connect the CPU cooler power connector to the CPU_FAN con­nector located on the motherboard so that the CPU cooler can properly function to prevent CPU overheating.
The CPU cooler may adhere to the CPU as a result of hardening of the heat paste. To prevent such an occurrence, it is suggested that either thermal tape rather than heat paste be used for heat dissipation or using extreme care when removing the CPU cooler.

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 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 DDRII 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 II
Fig.1 The DIMM socket has a notch, so the DIMM memory module can only fit in one direction. Insert the DIMM memory module vertically into the DIMM socket. Then push it down.
Fig.2 Close the plastic clip at both edges of the DIMM sockets to lock the DIMM module. Reverse the installation steps when you wish to remove the DIMM module.
GA-M55S-S3 Motherboard - 14 -
Dual Channel Memory Configuration
The GA-M55S-S3 supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will double.
Due to CPU limitation, if you wish to operate the Dual Channel Technology, follow the guidelines below:
1. Dual Channel mode will not be enabled if only one memory module is installed.
2. To enable Dual Channel mode with two memory modules (it is recommended to use memory modules of identical brand, size, chips, and speed), you must install them into DIMM sockets of the same color.
3. To enable Dual Channel mode with four memory modules, it is recommended to use memory modules of identical brand, size, chips, and speed.
The following is a Dual Channel Memory configuration table: (DS: Double Side, SS: Single Side, "--": Empty)
DIMM Socket
2 memory modules
4 memory modules
If two memory modules are to be used to achieve Dual Channel mode, we recommend installing them in DDRII_1 and DDRII_2 DIMM sockets.

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 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 (400W 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.
