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.
If you have a C1 get a warranty replacement. Intel is probably going to sell the recovered C1's in Dell workstations as refurbished or something with a specific stipulation that VT-d will not work.
I have my warranty C2 running right now as we speak and the chip feels smoother to me than the first chip. I know that is in my imagination but it is running at a much lower voltage and no LLC activated than my C1 and VT-d works.
