USER MANUAL GA-A55M-S2H GIGABYTE

The sequence of installation may differ depending on the type of case and devices used. The installation instructions below apply to GIGABYTE's desktop systems and are for reference only.
Refer to the user's manual included for detailed motherboard specifications.
- Before installing the devices, make sure they are compliant with the connectors on your computer.
- Before installing the devices, be sure to turn off the devices and your computer. Unplug the power cord from the power outlet to prevent damage to the devices and the system components.
- Place the computer system on a stable surface to prevent improper installation resulted from shaking.

Installing a CPU and CPU Cooler

A. Installing an Intel CPU (skip this step if the motherboard has a built-in CPU)

A-1 Refer to the following instructions based on your CPU specifications:

• Type A:

Lift the CPU socket lever and the metal load plate will be lifted as well.

a. If the protective socket cover is fastened on the CPU socket, remove it first.
b. If the protective socket cover is fastened on the metal load plate, do not remove it at this stage. The socket cover may pop off from the load plate automatically during the process of re-engaging the lever after you insert the CPU.

• Type B:

Push lever A (closest to the "□" marking) down and away from the socket to release it. Then push lever B (closest to the "□" marking) down and away from the socket and lift it. Gently press lever A to allow the load plate to rise. Open the load plate.

A-2 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.
A-3 Once the CPU is properly inserted, replace the load plate and push the CPU socket lever back into its locked position. Once the type B is properly inserted, carefully replace the load plate. Then secure lever B under its retention tab. The socket cover may pop off from the load plate during the process of engaging the lever. Finally, secure lever A under its retention tab to complete the installation of the CPU.

For detailed instructions on installing the CPU, please refer to the user's manual.

B. Installing an AMD CPU (skip this step if the motherboard has a built-in CPU)

B-1 Completely raise the CPU socket lever. Align the CPU pin one (small triangle marking) with the triangle marking on the CPU socket and gently insert the CPU into the socket. Make sure that the CPU pins fit perfectly into their holes.
B-2 Once the CPU is positioned into its socket, place one finger down on the middle of the CPU, lowering the socket lever and latching it into the fully locked position.

• Do not force the CPU into the CPU socket. The CPU cannot fit in if oriented incorrectly. Adjust the CPU orientation if this occurs.
• DO NOT touch socket contacts. To protect the CPU socket, always replace the protective socket cover when the CPU is not installed.

C. Installing the CPU cooler

C-1 Before installing the CPU cooler, please first add a thin layer of heat sink paste on the surface of the CPU. Then install the cooler (refer to the installation manual for your CPU cooler).
C-2 Connect the CPU cooler cable to the CPU_FAN connector located on the motherboard so that the cooler can properly function to prevent the CPU from overheating.

Installing Memory

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. The clips at both ends of the socket will snap into place when the memory module is securely inserted.

Preparing the Case and Installing a Power Supply

Using the GIGABYTE desktop system as the demonstration example, please first remove both sides and the lid of the case in order to install the power supply. Place the power supply in the correct place in the case and secure it with screws. Installation and placement of the power supply may differ depending on the type of case used.

To ensure sufficient power can be supplied to your system, it is recommended that a power supply of good quality be used. If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.
