Setup
1. Physical Installation

- Run the downloaded driver installer and follow the on-screen instructions. A system restart may be required.
Operating
1. Connecting Displays
Connect your display(s) to the available ports on the graphics card (HDMI 2.1, DisplayPort 1.4a). The card supports multiple displays.
2. ASUS GPU Tweak III
For advanced monitoring, tuning, and customization of your graphics card, download and install ASUS GPU Tweak III from the official ASUS website. This utility allows you to adjust clock speeds, voltage, fan performance, and monitor hardware status.
Maintenance
- Regularly clean dust from the graphics card fans and heatsink using compressed air. Ensure the computer is powered off and unplugged before cleaning.
- Maintain good airflow within your computer case by ensuring proper cable management and fan placement.
- Keep drivers updated to ensure optimal performance and stability.
Troubleshooting
- No Display Output: Ensure the graphics card is fully seated in the PCIe slot and all power connectors are securely attached. Verify your monitor is connected to the graphics card, not the motherboard's integrated graphics.
- System Instability/Crashes: Check that your power supply meets the recommended wattage. Ensure drivers are correctly installed and up to date. Monitor temperatures using GPU Tweak III to rule out overheating.
- Fan Noise: While the card is designed for quiet operation, high loads may increase fan speed. Ensure no cables are obstructing the fans. Clean any dust accumulation.
- Performance Issues: Verify that the latest drivers are installed. Check background applications that might be consuming resources.
