Sigurnosne informacije

Observe the following safety precautions to prevent damage to the graphics card or other components, and to ensure personal safety:

• Uvijek isključite napajanje računara prije instaliranja ili uklanjanja bilo kakvih komponenti.
• Nosite antistatičku narukvicu ili često dodirujte uzemljeni metalni predmet kako biste ispraznili statički elektricitet prije rukovanja grafičkom karticom.
• Držite grafičku karticu za rubove kako biste izbjegli dodirivanje osjetljivih komponenti.
• Osigurajte odgovarajuću ventilaciju unutar kućišta računara kako biste spriječili pregrijavanje.
• Ne izlažite grafičku karticu vlazi ili ekstremnim temperaturama.

Setup

Sistemski zahtjevi

• Matična ploča kompatibilna s PCI Express standardom s jednim ili više x16 grafičkih slotova.
• Minimum 750W power supply with two 8-pin PCI Express power connectors.
• Minimalno 4 GB sistemske memorije (preporučuje se 8 GB).
• Supported operating system (e.g., Windows 7, Windows 8, Windows 10).
• CD-ROM drive or internet connection for driver installation.

Fizička instalacija

1. Pripremite svoj računar: Isključite računar i iskopčajte kabl za napajanje. Otvorite kućište računara.
2. Locate a PCI Express x16 slot: Identify an available PCI Express x16 slot on your motherboard. This card is large; ensure sufficient physical clearance.
3. Uklonite poklopce utora: Remove the metal slot covers from the back of your computer case corresponding to the chosen PCIe slot.
4. Instalirajte grafičku karticu: Pažljivo poravnajte grafičku karticu sa PCIe utorom i čvrsto je pritisnite dok se ne učvrsti. Provjerite da li je kopča za zadržavanje zaključana na svoje mjesto.
5. Povežite kablove za napajanje: Connect two 8-pin PCI Express power connectors from your power supply to the corresponding ports on the top edge of the graphics card. Ensure a secure connection.

6. Osigurajte karticu: Use screws to secure the graphics card's bracket to the computer case.
7. Zatvorite slučaj: Replace the computer case cover and reconnect the power cable.

Instalacija drajvera

1. Uključeno: Connect your monitor to one of the graphics card's display outputs (DVI-I or Mini DisplayPort) and power on your computer.
2. Initial boot: The operating system may install a generic display driver.
3. Install AMD drivers:
   • Insert the driver CD (if included) and follow the on-screen instructions.
   • Alternatively, download the latest drivers from the official AMD webstranica (www.amd.com/support). Select your graphics card model and operating system.
4. Ponovno pokretanje: Ponovo pokrenite računar nakon što je instalacija upravljačkog programa završena.

Operating

Povezivanje ekrana

The Sapphire Radeon HD 7990 supports multiple display configurations. It features the following output ports:

• 1 x Dual-Link DVI-I port
• 4 x Mini DisplayPort (mDP) ports

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, aktivan 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.

Održavanje

Pravilno održavanje osigurava dugotrajnost i optimalne performanse vaše grafičke kartice.

• čišćenje: 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.
• Ažuriranja drajvera: Redovno provjeravajte službene AMD webStranica za najnovije grafičke drajvere. Ažuriranje drajvera može poboljšati performanse, stabilnost i kompatibilnost s novim softverom i igrama.
• Praćenje temperature: Use monitoring software to keep track of the card's operating temperatures, especially under load. Ensure your system has adequate airflow.

Rješavanje problema

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

• Nema izlaza za prikaz:
  • Provjerite je li monitor povezan s grafičkom karticom, a ne s integriranom grafikom matične ploče.
  • Provjerite da li je grafička kartica u potpunosti umetnuta u PCIe slot.
  • Confirm that both 8-pin PCIe power connectors are securely attached.
  • Ako je moguće, testirajte s drugim kabelom za prikaz ili monitorom.
• Poor Performance or Crashes:
  • Provjerite imate li instalirane najnovije grafičke drajvere sa službenog AMD-ovog website.
  • Check for overheating. Monitor GPU temperatures during demanding tasks. Improve case airflow if temperatures are consistently high.
  • Provjerite da vaše napajanje ispunjava minimalnu snagutage requirement and provides stable power.
  • Zatvorite nepotrebne pozadinske aplikacije.
• Zujanje zavojnice: 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.
• Problemi sa vozačem: 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.
