I have a Chinese x79 "Atermiter x79g" motherboard working with a xeon e5 2620, 16gb ram and was thinking about upgrading to a xeon e5 2689 but I found the Xeon e7 4890 v2 at a good price and with interesting features (15 cores and 30 threads at 3.4ghz) just for the lga 2011, and I'm left with the doubt ..., Is it compatible with my motherboard?
