I have a kit (2x8gb) of this, seemingly obscure ram from EVGA that they had at microcenter for a while. I remember the guy talking me into it.. So far its been amazing. Yet now that I plan to upgrade, I was looking for another 2x8gb kit and it seems to have been discontinued.

So my question is, should I just start over and get another kit? or is there any way that I can mix these two with another 2x8gb kit of PC4-25600?
