Setup
Install CPU & Fan
Please install the CPU into the CPU socket (LGA 2011-3) as shown below.

Image: Step-by-step diagram illustrating the installation of the CPU into the LGA 2011-3 socket and the subsequent installation of the CPU cooler.
Important Considerations:
- Ensure the motherboard supports the specific CPU model.
- 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 power on the computer if the CPU cooler is not installed; overheating and damage may occur.
- Confirm the CPU heatsink forms a tight seal with the CPU before booting.
- Apply an even layer of thermal paste (or thermal tape) between the CPU and heatsink for optimal heat dissipation.
- When the CPU is not installed, protect the CPU socket pins with a plastic cap.
- Locate pin one of the CPU socket and the CPU. Position the CPU into its socket, then gently lower the locking lever until it latches into the fully locked position.
- Do not force the CPU into the socket if the locking lever is not lifted, as this can damage the CPU or socket.
- Connect the CPU heatsink's 4-pin fan power connector to the 4-pin CPU fan header on the motherboard.
- Ensure the 8-PIN power supply is plugged in to power the CPU.
Install Memory
The motherboard provides 4 DDR4 DIMM slots, each 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.
- Flip the latches on both sides of the slot to lock the memory.

Image: Diagram showing the steps for installing memory modules into the DIMM slots, including opening latches, inserting the module, and closing latches.
Important Considerations:
- Ensure the motherboard supports the memory. It is recommended to use memory of the same capacity, brand, speed, and chips.
- Always turn off the computer and unplug the power cord before installing memory.
- Memory modules have a foolproof design; they can only be installed in one direction. Do not force.
- The stability and compatibility of installed memory depend on the CPU and devices when overclocking.
- This motherboard supports quad-channel technology. Install 4 memory modules for quad-channel mode, and 2 for dual-channel mode.
- When installing memory, prioritize slots closest to the CPU first. Refer to the table below for recommended configurations:
| Configuration | DIMMD1 | DIMMD2 | DIMMB1 | DIMMB2 |
|---|---|---|---|---|
| 1 Module | Y | -- | -- | -- |
| 2 Modules | Y | -- | Y | -- |
| 4 Modules | Y | Y | Y | Y |
("Y"=Install memory, "--"=No Memory)
Install Expansion Card
The motherboard provides 1 PCI Express 3.0 x16 expansion slot and 1 PCI Express 3.0 x1 expansion slot. Place the expansion card in an available PCI Express slot and press it until it is fully inserted.

Image: Diagram showing the PCI Express x16 and x1 slots and how to insert an expansion card.
Important Considerations:
- When adding or removing expansion cards, always turn off the power supply and unplug the power cable to prevent hardware damage.
- If the expansion card is not installed correctly, it may cause a short circuit, potentially damaging the card or the motherboard.

Operating
BIOS Setup
The BIOS (Basic Input and Output System) stores hardware parameters in the CMOS. It identifies, configures, tests, and connects computer hardware to the OS upon startup. Key functions include Power-On Self-Test (POST), saving system parameters, and loading the operating system. The BIOS Setup program allows users to modify basic system configurations or activate specific features.
When the power is off, the motherboard's battery supplies power to the CMOS to retain configuration values.
Important:
BIOS flashing is risky. Only flash the BIOS if you encounter problems with the current version. Inadequate flashing can lead to system malfunction.
Enter BIOS Setup
When the computer starts up, the BIOS performs a self-test. Once complete, a message like "Press DEL key to enter Setup Menu" will appear. Press the <Delete> key to enter the BIOS setup.
If the message disappears too quickly, you can restart your computer by pressing <Delete> or <Ctrl>+<Alt>+<Delete> simultaneously.
Important:
Functions and menu options may vary depending on the specific BIOS version.
Maintenance
JCMOS1: CMOS Discharge
To clear the CMOS data, follow these steps:

Image: Diagram showing the three states of the JCMOS1 jumper for CMOS discharge: Initial state (pins 1-2 covered), Discharge state (pins 2-3 covered), and Restored state (pins 1-2 covered after discharge).
- **Initial state:** The jumper covers pins "1" and "2".
- **Discharge:** Pull out the jumper cap and place it to cover pins "2" and "3". Wait for approximately 3 minutes for the discharge to complete.
- **Restore:** After discharge, restore the jumper to its initial state, covering pins "1" and "2".
Important:
Always turn off the computer and unplug the power cord from the power outlet before discharging the CMOS.
Reset BIOS
If you need to restore default BIOS settings to resolve issues, you can:
- Go to BIOS and press F6 to load optimized defaults.
- Short the Clear CMOS jumper on the motherboard (refer to JCMOS1: CMOS Discharge instructions above).
Important:
Ensure the computer is off before clearing CMOS data.
Troubleshooting (FAQs)
No Boot (Computer does not respond, fans not rotating, indicator lights off)

- Replace the power supply.
User Tips
- RAM Compatibility: The motherboard supports DDR4 memory. For optimal performance and stability, especially when using multiple modules, ensure they are of the same capacity, brand, speed, and chip type. This motherboard supports both desktop (unbuffered) and ECC (Error-Correcting Code) server RAM. When installing, follow the recommended slot population for dual or quad-channel configurations as outlined in the 'Install Memory' section.
- CPU Compatibility: This motherboard is designed for Intel Xeon E5 LGA2011-3 series processors, specifically E5-26xx V3 series. While some V4 processors might physically fit, full compatibility and feature support are not guaranteed. Always verify your CPU model against the motherboard's supported list.
- TPM 2.0 and Windows 11: The motherboard may not have a built-in Trusted Platform Module (TPM) 2.0 chip. However, it might feature a header for an optional TPM module. If Windows 11 compatibility is crucial, you may need to acquire and install a compatible TPM 2.0 module.
- CPU Cooler Installation: The kit includes an LGA2011-3 cooler bracket mounting kit. Ensure you have a compatible CPU cooler and apply thermal paste correctly for efficient heat dissipation. Improper cooling can lead to system instability or damage.
- BIOS Updates and Drivers: For the latest performance enhancements, bug fixes, and compatibility, regularly check the manufacturer's official website for updated BIOS versions and drivers (including audio drivers). Exercise caution when updating BIOS, as improper procedures can lead to system malfunction.
