4. Installation

4.1 Physical Installation

1. Prepare your system: Power off your computer and disconnect all cables. Open the computer case.
2. Locate the PCIe x16 slot: Identify an available PCI Express x16 slot on your motherboard. Remove any expansion slot covers that obstruct the installation.
3. Install the graphics card: Carefully align the graphics card with the PCIe x16 slot and press it firmly until it is securely seated. Ensure the retention clip on the motherboard slot locks into place.
4. Secure the card: Fasten the graphics card to the computer case with screws.
5. Install the VGA Support Kit: Due to the size and weight of the card, it is highly recommended to install the included VGA Support Kit (anti-sag bracket) to prevent GPU sag and potential damage to the PCIe slot. Follow the instructions provided with the support kit for proper installation.

7. Troubleshooting

If you encounter issues, refer to the following common problems and solutions:

• No Display Output:
  • Ensure the monitor cable is securely connected to both the graphics card and the monitor.
  • Verify that the graphics card is fully seated in the PCIe slot.
  • Check that all power cables are correctly connected to the graphics card and the power supply. Insufficient power can prevent the card from initializing.
  • Test with a different display cable or monitor if possible.
• System Fails to Boot or Shuts Down:
  • Confirm your Power Supply Unit (PSU) meets the recommended wattage (750W or higher) and has sufficient power connectors. An underpowered PSU can cause instability.
  • Ensure the 16-pin power cable is fully inserted into the graphics card and the PSU. Loose connections can lead to power delivery issues.
  • Check for any loose components or short circuits within the case.
• Driver Installation Issues:
  • Download the latest drivers directly from the official NVIDIA website.
  • Uninstall any previous graphics drivers using a utility like Display Driver Uninstaller (DDU) before attempting a fresh installation.
  • Temporarily disable antivirus software during driver installation.
• Poor Performance in Games/Applications:
  • Ensure you have the latest graphics drivers installed.
  • Check in-game settings; some settings may be too demanding for your current resolution or refresh rate.
  • Monitor GPU temperature and utilization to identify potential thermal throttling or bottlenecks.
  • Verify that your monitor is connected to the graphics card and not the motherboard's integrated graphics.
