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.
Free bump. Dual mining here. Does not use that much power I would say about 10% more. My gtx 1070s have to be set at 75% power to get dual mining working. But just eth they require only 70% so about 5% difference. Shouldn't change much with your cards either. My cards use around 90-100w I would say. Because with risers they are actually getting less power then specified. Running these on a 1000w power supply. Should be no different for your cards. Hope this helps those looking to mine with these.
