Install CPU & Fan

Please install the CPU into the CPU socket as shown below.

Important

Make sure that the motherboard supports the CPU.
Always unplug the power cord from the power outlet before installing or removing the CPU to prevent hardware damage.
Please retain the CPU protective cap after installing the processor.
Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage to the CPU may occur.
Confirm that the CPU heatsink has formed a tight seal with the CPU before booting your system.
Apply an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to enhance heat dissipation.
Whenever the CPU is not installed, always protect the CPU socket pins by covering the socket with a plastic cap.
Locate the pin one of the CPU socket and the CPU. Once the CPU is positioned into its socket, place one finger down on the middle of the CPU, lowering the locking lever and latching it into the fully locked position.
Do not force the CPU into the CPU socket before the CPU socket locking lever is lifted up, or damage to the CPU and CPU socket may occur.
Connect the CPU heat sink’s 4pin fan power connector to the 4pin CPU fan header on the motherboard.

Install Memory

The motherboard provides 2 DDR3 DIMM slots with a maximum capacity of 32GB.

Wrench the latches on both sides of the memory slot outwards.
Insert the memory into the slot by aligning it with the notch in the slot.
Flip the latches on both sides of the slot to lock the memory.

Important

Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used.
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.
The stability and compatibility of the installed memory module depend on the installed CPU and devices when overclocking.
This motherboard provides two memory sockets and supports Dual Channel Technology. Dual-Channel mode cannot be enabled if only one memory module is installed

Install Expansion Card

The motherboard provides a PCI Express 2.0 x16 expansion slot. Place the expansion card in an available PCI Express slot and press the expansion card until itis fully inserted into the slot.

Important

When adding or removing expansion cards, always turn off the power supply and unplugthe power supply power cable from the power outlet to prevent hardware damage.
If the expansion card is not installed correctly, it may cause a short circuit throughout themetal pins, which could burn out the expansion card or the motherboard.

BIOS Setup

BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the motherboard. BIOS identifies, configures, tests and connects computer hardware to the OS immediately after a computer is turned on. Its major functions include conducting the Power-On Self-Test (POST) during system startup, saving system parameters and loading the operating system, etc. BIOS includes a BIOS Setup program that allows the user to modify basic system configuration settings or to activate certain system features. When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to keep the configuration values in the CMOS.

Important: 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.

The default settings offer the optimal performance for system stability in normal conditions. 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 the system’s failure to boot.

Important: BIOS items are regularly updated for better system performance. The items may be slightly different from the latest BIOS; therefore, the description is for reference only

Enter BIOS Setup

Entering BIOS Setup
When the computer starts up, BIOS enters the self-test process. When the self-test is completed, the following message is displayed: Press DEL key to enter Setup Menu. At this time, Press key to enter the BIOS setup. If this message disappears before you press you can turn it off and then turn on your computer or press on the case to restart your computer. You can also press++ at the same time to restart your computer. It is recommended to repeatedly press the “Del” key immediately after starting the computer to ensure that the computer can enter BIOS mode.

Current Version

Important: Functions may vary depending on the product you have.

When you need to restore the default BIOS settings to resolve certain issues, thereareseveral ways to reset the BIOS:

Go to BIOS and press F6 to load optimized defaults.
Short the Clear CMOS jumper on the motherboard.

Important: Be sure the computer is off before clearing CMOS data. Please refer to the Clear CMOSjumper section for resetting BIOS.
