My question is exactly the same as the one here:
I also bought the X550 T2 from Newegg.com (sold by Newegg, not a third-party) and the yottamark says that it is genuine and the part name and PBA number are correct, but the MAC address differs from the one on the sticker of the card.
Is there an Intel Employee that I can contact to verify that this card is genuine before my return period is over?
Thank you for posting in Wired Communities. I am sorry to hear what happened and I have sent a PM to you for the Yottamark detail, please reply from there so that I can check for you internally as well. Thank you.
