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.
use something like Radlinker or Rage3D or AtiTool and see how high it'll go.
AtiTool usually does a decent job, and has a feature to find max mem and find max core speeds. Don't click and walk away for a while though. stay close by just in case something goes squirly and it doesn't back the clock down when it detects artifacts.
