Hey folks,
I have just picked up this card and I'm having the same problem.
I followed the steps, but when I flash by BIOS, windwos doesn't like the card anymore. Device manager gives the error with the yellow triangle thing. Had to re-flash back to stock.
I think this is because I have a new card and the app isn't updated.
Is there any word if Gigabyte will release a legit bios update, or if there is anything else I can do to fix this problem? I guess Maxwell bios tweaker needs an update or something....

I was choosing between the asus strix card and this one, almost regretting my purchase now this sound is bugging me...
