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.
Speed....I own the GEIL DDR2-533 and i like it, does what its supposed to do i guess. 533/2=266 and 667/2=333 so, if youre not doing any overclocking 533 is fine because the FSB is only 800 in the first place so a divider will be used.
