5. Safety Precautions

Failure to follow these precautions may result in equipment damage or personal injury.

• Always ensure the power supply is disconnected from the system before installing or removing any components.
• When connecting cables, carefully identify the correct direction. Do not force connections, as this can damage the pins or equipment.
• Connect the cable to the equipment socket first, then connect the other end.
• Avoid excessive force when plugging or unplugging cables to prevent bending or breaking pins.
• Ensure proper ventilation for all components, especially in mining setups, to prevent overheating.
• The power cord uses pure copper wire to prevent oxidation and burning during operation. Do not substitute with inferior cables.

6. Setup Instructions

Follow these steps to properly install your MZHOU PCI-E 1X to 16X Riser Card:

1. Prepare Your System: Ensure your computer or mining rig is powered off and disconnected from the main power source.
2. Install PCI-E 1X Plug-in Card: Insert the small PCI-E 1X plug-in card into an available PCI-E 1X slot on your motherboard. Ensure it is seated firmly.
3. Connect USB 3.0 Cable: Connect one end of the provided USB 3.0 cable to the USB port on the PCI-E 1X plug-in card. Connect the other end of the USB 3.0 cable to the USB port on the PCI-E 16X main riser card.

6. Power On: Once all connections are secure, reconnect your system to the power source and power it on. The LED indicator on the riser card should illuminate, confirming power.
7. Driver Installation: Install the necessary drivers for your graphics card as you normally would.

7. Operating Instructions

Once installed and powered, the MZHOU PCI-E 1X to 16X Riser Card operates transparently, extending the PCI-E slot for your graphics card. Ensure your operating system and mining software recognize the graphics card connected via the riser. Monitor the LED indicator on the riser card to confirm it is receiving power and functioning correctly.

8. Maintenance

• Dust Removal: Regularly clean the riser cards and connected components to prevent dust buildup, which can lead to overheating and reduced performance. Use compressed air or a soft brush.
• Cable Inspection: Periodically check all cables (USB 3.0, power) for any signs of wear, damage, or loose connections. Replace damaged cables immediately.
• Environmental Control: Operate the riser cards in a well-ventilated, cool, and dry environment to maximize their lifespan and prevent component stress.

9. Troubleshooting

• Graphics Card Not Detected:
  • Ensure all cables (USB 3.0, power) are securely connected.
  • Verify the PCI-E 1X plug-in card is fully seated in the motherboard slot.
  • Check if the graphics card is properly seated in the 16X riser slot.
  • Confirm the riser card's LED indicator is lit.
  • Try a different PCI-E slot on the motherboard or a different USB 3.0 cable.
  • Ensure your motherboard BIOS settings are configured correctly for multiple GPUs (e.g., PCI-E Gen1/Gen2 setting, 4G Decoding enabled).
• System Instability/Crashes:
  • Ensure your power supply unit (PSU) has sufficient wattage for all connected graphics cards and components.
  • Check for overheating. Improve ventilation if necessary.
  • Verify that the 6PIN power cable is securely connected to the riser card and the PSU.
  • Update graphics card drivers to the latest version.
• LED Indicator Not Lit:
