Öryggisupplýsingar

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

• Aftengdu alltaf rafmagnið frá tölvunni áður en þú setur upp eða fjarlægir nokkra íhluti.
• Notið úlnliðsól með rafstöðurafmagni eða snertu oft jarðtengdan málmhlut til að losa um stöðurafmagn áður en skjákortið er meðhöndlað.
• Haltu skjákortinu á brúnunum til að forðast að snerta viðkvæma íhluti.
• Tryggið næga loftræstingu í tölvukassanum til að koma í veg fyrir ofhitnun.
• Ekki láta skjákortið verða fyrir raka eða miklum hita.

Uppsetning

Kerfiskröfur

• PCI Express-compliant motherboard with one or more x16 graphics slots.
• Minimum 750W power supply with two 8-pin PCI Express power connectors.
• Lágmark 4GB kerfisminni (8GB mælt með).
• Supported operating system (e.g., Windows 7, Windows 8, Windows 10).
• CD-ROM drive or internet connection for driver installation.

Líkamleg uppsetning

1. Undirbúið tölvuna ykkar: Slökktu á tölvunni og aftengdu rafmagnssnúruna. Opnaðu tölvukassann.
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. Fjarlægðu raufarhlífar: Remove the metal slot covers from the back of your computer case corresponding to the chosen PCIe slot.
4. Settu upp skjákortið: Stilltu skjákortinu vandlega saman við PCIe raufina og þrýstu því fast þar til það situr örugglega á sínum stað. Gakktu úr skugga um að festingarklemman læsist á sínum stað.
5. Tengdu rafmagnssnúrur: 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. Tryggið kortið: Use screws to secure the graphics card's bracket to the computer case.
7. Lokaðu málinu: Settu hlífina á tölvukassann aftur og tengdu rafmagnssnúruna aftur.

Uppsetning bílstjóri

1. Kveikt á: 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 webvefsvæði (www.amd.com/support). Select your graphics card model and operating system.
4. Endurræsa: Endurræstu tölvuna eftir að uppsetningu bílstjórans er lokið.

Að tengja skjái

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, virkur 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.

Viðhald

Rétt viðhald tryggir langlífi og bestu mögulegu afköst skjákortsins.

• Þrif: 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.
• Bílstjóri uppfærslur: Athugaðu reglulega opinberu AMD website for the latest graphics drivers. Keeping drivers updated can improve performance, stability, and compatibility with new software and games.
• Vöktun hitastigs: Use monitoring software to keep track of the card's operating temperatures, especially under load. Ensure your system has adequate airflow.

Úrræðaleit

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

• Engin skjáúttak:
  • Gakktu úr skugga um að skjárinn sé tengdur við skjákortið, ekki við innbyggða skjákortið í móðurborðinu.
  • Gakktu úr skugga um að skjákortið sé alveg sett í PCIe raufina.
  • Confirm that both 8-pin PCIe power connectors are securely attached.
  • Prófaðu með annarri skjásnúru eða skjá ef mögulegt er.
• Poor Performance or Crashes:
  • Ensure you have the latest graphics drivers installed from AMD's official websíða.
  • Check for overheating. Monitor GPU temperatures during demanding tasks. Improve case airflow if temperatures are consistently high.
  • Gakktu úr skugga um að aflgjafinn þinn uppfylli lágmarks wattkröfurtage requirement and provides stable power.
  • Lokaðu óþarfa bakgrunnsforritum.
• Spóluhvín: 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.
• Vandamál ökumanns: 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.
