I'm trying to figure out the difference between two ram chips. The KHX1600C9D3X2K2 and the KHX1600C9D3K2.
There seems to be no difference at all between the two except for the extra
X2 in the name of the first.
I am asking because I am going to use one of them with an
i7 3770k and
ASUS P8Z77-V PRO.
