GIGABYTE MZ73-LM0 (01) PDF Document

Prior to installation, follow these procedures to prevent damage from electrostatic discharge (ESD):

Do not remove or break the motherboard serial number or warranty stickers provided by your dealer.

Always remove the AC power by unplugging the power cord from the power outlet before installing or removing motherboard components.

When connecting hardware components to the internal connectors, make sure they are connected tightly and securely.

Avoid touching any metal leads or connectors when handling the motherboard.

It is best to wear an ESD wrist strap. If you do not have one, keep your hands dry and first touch a metal object to eliminate static electricity.

Place the motherboard on top of an antistatic pad or within an electrostatic shielding container during installation.

Ensure the power supply is turned off before unplugging the power supply cable.

Verify that the power supply voltage is set according to the local voltage standard before turning on the power.

Make sure there are no leftover screws or metal components on the motherboard or within the computer casing.

Do not place the system on an uneven surface or in a high-temperature environment.

The GIGABYTE MZ73-LM0 features the following specifications:

Follow these steps to install the CPU:

Step 1. Loosen the captive screw securing the CPU cover.

Step 2. Flip open the CPU cover.

Step 3. Remove the CPU carrier from the CPU frame using the handle on the CPU carrier.

Step 4. Using the handle on the CPU carrier, insert the new CPU carrier with the CPU installed into the CPU frame. Ensure the CPU is in the correct orientation, with the triangle aligned to the top left corner of the carrier.

Step 5. Flip the CPU frame with the CPU installed into place in the CPU socket.

Step 6. Flip the CPU cover into place over the CPU socket.

Step 7. Tighten the CPU cover screw to secure it. Use a Torx T20 screwdriver with a tightening torque of 13.5 plus or minus 0.5 kgf-cm.

When installing memory modules, follow this configuration based on the quantity of DIMMs used per CPU:

Note: When only one DIMM per channel is used, it must be populated in memory slot DIMM1.

Follow these steps to install an optional M.2 SSD module:

Step 1. Insert the M.2 SSD module into the slot.

Step 2. Secure it with the screw, tightening as necessary to fasten the module in place.

Note: The position of the stand-off screw depends on the size of the M.2 device. The stand-off screw is pre-installed for 22110 cards as standard.

The 10GbE LAN port LEDs indicate the following states:

The 10/100/1000 management LAN LED indicates the following states:

The CLR_CMOS jumper is used to clear the CMOS values and reset the board to default values. The jumper settings are as follows:

Pins 1-2 Closed: Default operation.

Pins 2-3 Closed: Enable Clear CMOS.

Note: Always turn off the computer and unplug the power cord before adjusting jumper settings.

If the BIOS becomes corrupt, use the following recovery instructions:

Step 1. Copy the recovery ROM file (XXX.rom) to a USB diskette.

Step 2. Set the BIOS Recovery jumper to the enabled status.

Step 3. Boot the system into BIOS recovery mode.

Step 4. Select and run “Proceed with flash update.”

Step 5. Wait for the update to complete and reboot the system when prompted.

During the Pre-EFI Initialization (PEI) phase, the following beep codes indicate specific issues:

During the Driver Execution Environment (DXE) phase, the following beep codes indicate specific issues:

The battery provides power to keep BIOS configurations and time information in the CMOS. Follow these instructions for replacement:

Step 1. Always turn off the computer and unplug the power cord before replacing the battery.

Step 2. Replace the battery with an equivalent model. Using an incorrect model poses a danger of explosion.

Step 3. Handle used batteries in accordance with local environmental regulations.

Step 4. Insert the new battery into the BAT (Battery Socket) ensuring correct polarity.
