Connect your monitors using appropriate cables. For Mini DisplayPort, you may need adapters depending on your monitor's input type (e.g., mDP to DisplayPort, mDP to DVI, mDP to HDMI). Note that for certain multi-monitor configurations, aktif Mini DisplayPort adapters may be required.

Multi-Display Setup (AMD Eyefinity)

The card supports up to 5 simultaneous displays using AMD Eyefinity technology. To configure multiple displays:

1. Ensure all monitors are physically connected to the graphics card.
2. Open the AMD Radeon Software (formerly Catalyst Control Center).
3. Navigate to the "Display" or "Eyefinity" section.
4. Follow the on-screen prompts to detect and arrange your displays. You can choose between extended desktop, duplicate, or Eyefinity group modes for a single large desktop experience.

Penyelenggaraan

Penyelenggaraan yang betul memastikan jangka hayat dan prestasi optimum kad grafik anda.

• Pembersihan: Periodically clean the fans and heatsink to remove dust buildup. Use compressed air to gently blow dust out of the fins and fan blades. Ensure the computer is powered off and unplugged before cleaning. Do not use liquid cleaners.
• Kemas Kini Pemandu: Semak AMD rasmi secara berkala website for the latest graphics drivers. Keeping drivers updated can improve performance, stability, and compatibility with new software and games.
• Pemantauan Suhu: Use monitoring software to keep track of the card's operating temperatures, especially under load. Ensure your system has adequate airflow.

Menyelesaikan masalah

If you encounter issues with your Sapphire Radeon HD 7990 graphics card, refer to the following common troubleshooting steps:

• Tiada Output Paparan:
  • Pastikan monitor disambungkan ke kad grafik, bukan grafik bersepadu papan induk.
  • Sahkan bahawa kad grafik dipasang sepenuhnya dalam slot PCIe.
  • Confirm that both 8-pin PCIe power connectors are securely attached.
  • Uji dengan kabel paparan atau monitor yang berbeza jika boleh.
• Poor Performance or Crashes:
  • Ensure you have the latest graphics drivers installed from AMD's official webtapak.
  • Check for overheating. Monitor GPU temperatures during demanding tasks. Improve case airflow if temperatures are consistently high.
  • Sahkan bekalan kuasa anda memenuhi kuasa minimumtage requirement and provides stable power.
  • Tutup aplikasi latar belakang yang tidak diperlukan.
• Gegelung Merengek: Some high-performance graphics cards may exhibit a high-pitched "coil whine" sound under heavy load. This is generally not indicative of a fault and is often related to power delivery components. While not always preventable, ensuring a stable power supply and good case airflow can sometimes mitigate it.
• Isu Pemandu: If you experience graphical glitches or instability after a driver update, try rolling back to a previous stable driver version or performing a clean installation of the latest drivers.
