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 recommended 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

The Top of Female Push Pin Female Push Pin
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.)
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 push pin. Check that the Male and Female push pins are joined closely. (Refer to your CPU cooler installation manual for instructions on installing the cooler.)
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.
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. - 17 Hardware Installation

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.

Read the following guidelines before connecting external devices: First make sure your devices are compliant with the connectors you wish to connect. 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. After installing the device and before turning on the computer, make sure the device cable has been securely attached to the connector on the motherboard. - 23 Hardware Installation
1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x12 Main 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, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design. Connect the power supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start. To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system. The main power connector is compatible with power supplies with 2x10 power connectors. When using a 2x12 power supply, remove the protective cover from the main power connector on the motherboard. Do not insert the power supply cable into pins under the protective cover when using a 2x10 power supply.

The front panel design may differ by chassis. A front panel module mainly consists of power switch, reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your chassis front panel module to this header, make sure the wire assignments and the pin assignments are matched correctly. GA-G31M-ES2L/ES2C Motherboard - 28 -
11) F_AUDIO (Front Panel Audio Header)
The front panel audio header supports Intel High Definition audio (HD) and AC'97 audio. You may connect your chassis front panel audio module to this header. Make sure the wire assignments of the module connector match the pin assignments of the motherboard header. Incorrect connection between the module connector and the motherboard header will make the device unable to work or even damage it.
For HD Front Panel Audio: Pin No. Definition MIC2_L GND MIC2_R -ACZ_DET LINE2_R FAUDIO_JD GND No Pin LINE2_L FAUDIO_JD
For AC'97 Front Panel Audio: Pin No. Definition 1 MIC 10 GND MIC Power NC Line Out (R) NC NC No Pin Line Out (L) NC
The front panel audio header supports HD audio by default. If your chassis provides an AC'97 front panel audio module, refer to the instructions on how to activate AC'97 functioninality via the audio software in Chapter 5, "Configuring 2/4/5.1-Channel Audio." Audio signals will be present on both of the front and back panel audio connections simultaneously. If you want to mute the back panel audio (only supported when using an HD front panel audio module), refer to Chapter 5, "Configuring 2/4/5.1/7.1-Channel Audio." Some chassis provide a front panel audio module that has separated connectors on each wire instead of a single plug.

This header supports digital S/PDIF out. Via an optional S/PDIF out cable, this header can connect to an audio device that supports digital audio in. For purchasing the optional S/PDIF out cable, please contact the local dealer.

Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction. BIOS will emit a beep code during the POST. Refer to Chapter 5, "Troubleshooting," for the beep codes description. It is recommended that you not alter the default settings (unless you need to) to prevent system instability or other unexpected results. Inadequately altering the settings may result in system's failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values. (Refer to the "Load Optimized Defaults" section in this chapter or introductions of the battery/clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)
