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.
When I originally bought my hardware upgrade I went with an Extreme6 instead of the Extreme6g/b which I could kick myself now since I actually need/want a sound card. Does anyone know of a way to purchase the addon card?
I'd probably call Asrock directly and inquire about buying one. If they won't do it or want to charge too much you could always go with a third party option.
