    Vega 64, every game is unplayable


      Edit: Turns out the cpu heat sink had came loose.



      Underload, notice the GPU MHz is very low.


      Everything runs at unplayable framerates.

      I had a R9 290 before and everything was fine.


      Is the GPU is faulty? OR it's almost like it's using the integrated graphics instead BUT its a desktop pc, and the monitor is connected to the card via a displayport cable.


      3D Mark results in a black screen then a reset.




      CPU - i7 4770K

      Mobo - Gigabyte 787X-UD3H-CF

      Ram - 32 GB DDR3

      GPU - Gigabyte RX Vega 64

      PSU - 750 watt

      OS - Windows 7 64 bit


      I have uninstalled and reinstalled drivers.

      I have gotten specific drivers (desktop, rx vega, windows 7 64 bit) from AMD's site.

      Changed PCI express slot.

      2 separate 8pin cables out the PSU to the card.


      Pretty desperate at this point.


      Edit: I put the old card back in, uninstalled the drivers, reset, ran Display Driver Uninstaller while in safe mode and shutdown.

      Put Vega in, installed drivers, no good.



      I did get 3d mark to work, it's like it's using the onboard graphics looking at the 3d mark results.




      "Graphics driver is not approved" I'll uninstall them again and try older ones.

          Hi 9warbane


          I have been experiencing the same problems as yourself. (Air Cooled RX Sapphire Vega 64)

          Im currently having a problem when running games such as PUBG (Constant crashes with PUBG error message appearing), OverWatch (Screen turns black and reappears only showing the game window border) and Rise of the Tomb Raider (Screen turns black and reappears only showing the game window border).


          Originally when playing PUBG my PC would power off, swapping out the faulty PSU (Silverstone SX800  - LTI) fixed that problem, so this new issue doesn't seem PSU related.


          I have noticed two things when i experience the crash.

          1. GPU gives a hard push of air and then game crashes.

          2. Back of the GPU has red LEDs ( not sure what technical term is) that seem to go ballistic just before the crash.


          I'm in work at the moment so i cannot send the spec of my PC, ill update it tonight with the troubleshooting steps i have taken
