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.
Alot of people use Coolbits which is a file that you just double click on and it adds a string to the registry that unlocks the ability to overclock in the nVidia driver properties but i didn't like it all that much because it s picky about how far it will let you overclock.
Most people use Rivatuner. I like it alot. And here is a guide on how to overclock using RivaTuner.
