Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I experienced this issue on my HD 5750, the clocks run at 400/900 while default is 700/1150
I fixed it by simply disable hardware acceleration setting in Adobe Flash Player
The problem now gone
Hope this helps you
Good luck
