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.
Not really. It's a personal preference. Using ECC is considered "slower memory" due to the error checking. But when you're talking milliseconds I personally don't think it's a noticable difference. It's not neccessary for a gaming machine and if you want to squeeze all you can performance wise, then go with non ecc.
You only need error checking in servers. There's no reason to have it on a gaming machine. It just wastes one extra clock cycle to check the memory for errors.
