I have just come across someone selling two 4 GB ram sticks, I asked if they were ECC registered and was in formed that they were not, but then he went to state that they were pulled from a freenas server. I looked up freenas server and it seems to be an operating system of sorts. Is there anything to worry about when I purchase them as I want to use it for personal computer uses. Any issues? If it helps the brand is "Super Talent".
