Setup
Overview of Components
Familiarize yourself with the layout of the motherboard to correctly identify all ports and connectors during installation.

Image Description: A detailed diagram of the MACHINIST X99 MR9A PRO motherboard, highlighting the locations of the CPU socket (LGA2011-3), DDR4 RAM slots, PCIe X16, X4, and X1 slots, NVMe M.2 slots, SATA ports, USB headers, fan headers, power connectors, and various other internal and external ports.
Install CPU & Fan
Follow these steps to install the CPU and its cooling fan:
- Open the CPU socket lever.
- Carefully align the CPU with the socket, ensuring the triangular mark on the CPU matches the mark on the socket.
- Gently place the CPU into the socket without forcing it.
- Close the socket lever to secure the CPU.
- Apply an even layer of thermal paste to the CPU's surface.
- Install the CPU cooler and fan assembly, ensuring it is securely mounted and the fan cable is connected to the CPU_FAN1 header.
Important Notes:
- 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 turn on the computer if the CPU cooler is not installed, as overheating and damage may occur.
- Confirm the CPU heatsink forms a tight seal with the CPU.
- Always protect CPU socket pins with a plastic cap when the CPU is not installed.
- Do not force the CPU into the socket.
- Connect the CPU heatsink's 4-pin fan power connector to the 4-pin CPU fan header on the motherboard.
Install Memory
The motherboard provides 4 DDR4 ECC DIMM slots with a maximum capacity of 64GB. Follow these steps to install memory modules:
- Wrench the latches on both sides of the memory slot outwards.
- Insert the memory into the slot by aligning it with the notch. Memory modules have a foolproof design and can only be installed in one direction.
- Flip the latches on both sides of the slot inwards to lock the memory module in place.
Important Notes:
- Ensure 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.
- The stability and compatibility of installed memory modules depend on the installed CPU and devices when overclocking.
- This motherboard supports 4-Channel Technology. 4-Channel mode cannot be enabled if only one memory module is installed.
- Server memory and desktop memory cannot be used together.
Install Expansion Card
The motherboard provides two PCI Express 3.0 X16 expansion slots, one PCI Express 3.0 X4 expansion slot, and one PCI Express 3.0 X1 expansion slot. To install an expansion card:
- Locate an available PCI Express slot suitable for your expansion card.
- Carefully align the expansion card with the slot.
- Press the expansion card firmly until it is fully inserted into the slot and secured by its retention clip.
Important Notes:
- When adding or removing expansion cards, always turn off the power supply and unplug the power cable from the power outlet.
- Incorrect installation may cause a short circuit, potentially damaging the expansion card or the motherboard.

Important Note:
An incorrect connection between a module connector and the motherboard header will make the device unable to work or may even damage it. Always refer to the motherboard layout diagram for correct pin assignments.
Operating
BIOS Setup
The BIOS (Basic Input and Output System) is crucial for identifying, configuring, testing, and connecting computer hardware to the operating system. It performs the Power-On Self-Test (POST) during startup and allows users to modify basic system settings.
Important Notes:
- The default settings offer optimal performance for system stability. It is recommended not to alter them unless necessary, as incorrect changes can lead to system instability or failure to boot.
- BIOS items are regularly updated; descriptions in this manual are for reference only and may slightly differ from the latest BIOS version.
Enter BIOS Setup
To enter the BIOS Setup Utility:
- Turn on your computer.
- Immediately and repeatedly press the DEL key during the Power-On Self-Test (POST) process.
- If the message disappears before you press DEL, you can restart your computer by pressing the reset button or by turning it off and on again. Alternatively, you can press Ctrl+Alt+Delete simultaneously to restart.
Maintenance
CMOS Discharge (Clear CMOS)
Clearing the CMOS memory can resolve issues caused by incorrect BIOS settings. Follow these steps to discharge the CMOS:
- Initial State: Locate the JCMOS1 jumper on the motherboard. In its initial state, the jumper cap covers pins 1 and 2.
- Discharge: Turn off the computer and unplug the power cord. Remove the jumper cap from pins 1 and 2, and place it over pins 2 and 3. Wait for approximately 3 minutes for the discharge to complete.
- Restitute: After the discharge, restore the jumper cap to its original position, covering pins 1 and 2.
Important Note:
Always turn off the computer and unplug the power cord from the power outlet before discharging the CMOS.
Troubleshooting
BIOS Reset
If you encounter issues that require restoring default BIOS settings, you can do so in a few ways:
- Through BIOS Setup: Enter the BIOS Setup Utility (as described in the Operating section) and press F6 to load optimized defaults. Save and exit.
- Clear CMOS Jumper: Use the CMOS discharge method described in the Maintenance section.
Important Note:
BIOS flashing is potentially risky. If you are not experiencing problems with the current BIOS version, it is recommended not to flash the BIOS. Proceed with caution, as inadequate flashing may result in system malfunction.
General Troubleshooting Tips
- No Power: Ensure all power cables (24-pin ATX, 8-pin CPU) are securely connected to the motherboard and power supply. Check the power supply unit (PSU) is switched on.
- No Display: Verify that the graphics card is properly seated in its PCIe slot and connected to the monitor. Check monitor input selection.
- System Instability: Ensure all components (CPU, RAM, expansion cards) are correctly installed. Check for adequate cooling. Verify that your power supply meets the system's power requirements (at least 500W recommended).
- Component Recognition Issues: Re-seat the component (RAM, M.2 SSD, expansion card). Check for bent pins on the CPU socket.
User Tips
