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.
Memtest86 is a simple program that you run and test your RAM for errors. If you dont get a single error then your RAM is good.
Most people use it along with Prime95 and other programs when they first put togethor their computer or when they are finding their system to be unstable.
