Installation

Install CPU & Fan

Follow these steps to install the CPU and its cooler:

1. Lift the CPU socket retention lever.
2. Align the CPU with the socket, noting the triangle/notch indicators, and gently place it into the socket.
3. Lower the retention lever to secure the CPU.
4. Remove the CPU protective cap.
5. Mount the CPU cooler according to its specific instructions.
6. Connect the CPU cooler's 4-pin fan power connector to the 4-pin CPU fan header on the motherboard.

⚠️ Important:

• Ensure the motherboard supports the CPU being installed.
• Always unplug the power cord from the power outlet before installing or removing the CPU to prevent hardware damage.
• Retain the CPU protective cap after installing the processor.
• Do not turn on the computer if the CPU cooler is not installed, as this can cause overheating and damage to the CPU.
• Confirm that the CPU heatsink has formed a tight seal with the CPU before booting.
• Apply an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to enhance heat dissipation.
• When the CPU is not installed, always protect the CPU socket pins by covering the socket with a plastic cap.
• Locate the pin one indicator on both the CPU socket and the CPU. Once the CPU is positioned into its socket, place a finger on the middle of the CPU, lower the locking lever, and latch it into the fully locked position.
• Do not force the CPU into the socket before the locking lever is lifted; this can damage the CPU and socket.

Install Memory

The motherboard provides 8 DDR4 ECC DIMM slots with a maximum capacity of 256GB.

Follow these steps to install memory modules:

1. Wrench the latches on both sides of the memory slot outwards.
2. Insert the memory module into the slot by aligning its notch with the notch in the slot.
3. Flip the latches on both sides of the slot inwards to lock the memory module.

⚠️ Important:

• Ensure the motherboard supports the memory modules. It is recommended to use memory of the same capacity, brand, speed, and chips.
• Always turn off the computer and unplug the power cord from the power outlet before installing memory to prevent hardware damage.
• Memory modules have a foolproof design; they can only be installed in one direction. If insertion is difficult, try flipping the module.
• The stability and compatibility of installed memory modules depend on the installed CPU and other devices, especially when overclocking.
• This motherboard provides 8 memory sockets and supports 4-Channel Technology. 4-Channel mode requires more than one memory module to be installed.
• Note: Server memory and desktop memory cannot be used together.

Install Expansion Card

The motherboard provides 2 PCI Express 3.0 x16 expansion slots, 1 PCI Express 3.0 x4 expansion slot, and 2 PCI Express 3.0 x1 expansion slots.

Place the expansion card into an available PCI Express slot and press down firmly until the card is fully inserted into the slot.

⚠️ Important:

• When adding or removing expansion cards, always turn off the power supply and unplug the power cable from the power outlet to prevent hardware damage.
• If an expansion card is not installed correctly, it may cause a short circuit through the metal pins, potentially damaging the card or the motherboard.

BIOS Setup

BIOS Overview

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. The BIOS includes a BIOS Setup program that allows users to modify basic system configuration settings or 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.

⚠️ Important:

Because BIOS flashing is potentially risky, it is recommended not to flash the BIOS unless you encounter problems with the current version. To flash the BIOS, proceed with caution, as inadequate flashing may result in system malfunction.

BIOS Setup (Default Settings)

The default settings offer optimal performance for system stability in normal conditions. It is recommended not to alter the default settings (unless necessary) 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 displayed may be slightly different from the latest BIOS; therefore, the description is for reference only.

Enter BIOS Setup

When the computer starts up, BIOS enters the self-test process. When the self-test is completed, a message like "Press DEL key to enter Setup Menu" is displayed. At this time, press the Delete key to enter the BIOS setup.

If this message disappears before you press the DEL key, you can turn the computer off and then on again, or press the Reset button on the case to restart. You can also press Ctrl+Alt+Delete simultaneously to restart.

It is recommended to repeatedly press the "Del" key immediately after starting the computer to ensure that the computer enters BIOS mode.

⚠️ Important:

Functions may vary depending on the specific product.

Reset BIOS

When you need to restore the default BIOS settings to resolve certain issues, there are several 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 CMOS jumper section for resetting BIOS.
