290X Unexplained drop in performance

Just a couple of days ago I noticed my CFX 290X (reference cooler) setup wasn't performing as good as it had been so I ran 3Dmark Firestrike to test it out and sure enough there was a drop of around 3k points from 15393 to 12801. I've changed no components and have tried sweeping the drivers and re-installing but it's made no difference. Does anyone have any ideas why or any recommendations on how to rectify this problem?

    Hello,
    It Is not a big problem, some people have reported this problem, it is about a bug within gpu fan rotation, read more here http://www.extremetech.com/gaming/170636-well-that-was-quick-amd-solves-r9-290-throttling-problem-with-a-new-driver which can be easily solved by downloading AMD Catalyst 13.11 beta 9.4 from www.AMD.com. Also if you card is Sapphire or Asus, they have released a new bios update which makes these changes coded in hardware.

  4. Check if your GPU still keeps frequencies and/or hits thermal threshold of 95C. I mean, if it doesn't hit 95C and still performs below 1GHz frequency, it may be hardware problem including PSU problem, though that PSU should be more than enough unless there is a problem with it.

    I am already on the beta 9.4 drivers and the problem is occurring. Also on sapphire's website it says the vBIOS update is for the 290 only. Would it do harm to go ahead and apply it to my 290x's?
  6. Yes, It will harm you GPU, can you tell me your core clock and memory clock in your catalyst center respectively?

    On load or idle?
  8. Load, of course.
  9. 787 GPU clock Mhz
    1250 Memory Clock Mhz
  10. Does the core go any higher than this when you load it? And what are temperatures when you load your card?

    It starts at 1000mhz then drops quickly my fans seem to power up to 90-94% rather quickly even though I have them set at 42% my temps are around 94C
  12. Sounds a lot like overheating for some reason if temperatures stay at 94C at 787MHz, especially with 90% fan speed. It shouldn't be that way even with stock cooler. You may have to RMA the card.
  13. 787 is very low.

    The new driver was released to solve exclusively the problem of throttling, that you are talking about, if the driver does not fix your problem, I'd say there is something more serious with the card, RMA your card and get it replaced.
