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.
They are great. I can run them at the low voltage with the advertised timings, or at 1.5 volts with 6-8-6-24 1t. Still tweaking, can probably get them lower.
Update: Now running at 6-7-6-21 1t @ 1.64 volts. Warranty for voltage is up to 1.65 volts.
Anything rated for no more than 1.50V (DDR3) or 1.80V (DDR2) and with clearly identifiable chip manufacturer markings. If you can't tell the chip maker from just looking at the chips and seeing either the logo of the company that diffused the chips (SEC, Hynix, Micron, etc.) or by Googling the part numbers, get some other modules. If you have to get something with no-name chips, consider Kingston because at least their RMAs always seem to be good, provided you spoke with 2nd level tech support and complained that their memory failed MemTest86 with several completely different computers.
