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 just did a similar build with the same mobo and CPU. Any chance you can share your OC settings? I've been playing around with mine and have yet to come up with anything stable that doesn't actually DROP my benchmark scores, even if it registers as a faster speed. But I'm still an OC'ing...
