Gigabyte HD 7770 GDDR5 1GB

Seller Description “Selling for spares or repairs. Was working fine until recently. Maybe you can fix it! Windows boots to desktop then the display will at some point go blank either when games are running or benchmark performance testing. The fan header pins were broken and soldered directly. Fan works as it should.”

First Impressions

  • In terms of visual overview, the card appears in very nice condition and in a nice original box!
  • Checking resistances before testing, what appears to be Vcore seems high to me at 32 Ohms, others seems OK, no obvious shorts.
  • The card is running Furmark HD stress testing to try and bring out the described behaviour. The card is kicking out some reasonable frames and holding at 58 degress C.
