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.
To the best of my knowledge, the min and max VID is not effected by overclocking or any other bios settings. Depending on your C1E / SpeedStep settings, VID can change between those two values. The main screen of RealTemp reports the current VID, while the Settings screen shows the possible range. On a mobile chip I've spotted 4 different VID values reported as the processor transitioned from idle to full load.
The single value that CoreTemp reports only tells you part of the VID story.
