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, نشيط 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.

صيانة

تضمن الصيانة المناسبة طول عمر بطاقة الرسوميات لديك وأدائها الأمثل.

• تنظيف: 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.
• تحديثات برنامج التشغيل: تحقق بانتظام من موقع AMD الرسمي website for the latest graphics drivers. Keeping drivers updated can improve performance, stability, and compatibility with new software and games.
• مراقبة درجة الحرارة: Use monitoring software to keep track of the card's operating temperatures, especially under load. Ensure your system has adequate airflow.

استكشاف الأخطاء وإصلاحها

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

• لا يوجد إخراج للعرض:
  • Ensure the monitor is connected to the graphics card, not the motherboard's integrated graphics.
  • تأكد من أن بطاقة الرسومات مثبتة بالكامل في فتحة PCIe.
  • Confirm that both 8-pin PCIe power connectors are securely attached.
  • قم بإجراء الاختبار باستخدام كابل عرض أو شاشة مختلفة إذا كان ذلك ممكنًا.
• Poor Performance or Crashes:
  • Ensure you have the latest graphics drivers installed from AMD's official webموقع.
  • Check for overheating. Monitor GPU temperatures during demanding tasks. Improve case airflow if temperatures are consistently high.
  • تأكد من أن مصدر الطاقة الخاص بك يفي بالحد الأدنى من متطلبات الطاقةtage requirement and provides stable power.
  • أغلق التطبيقات الخلفية غير الضرورية.
• Coil Whine: 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.
• مشاكل السائق: 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.
