I have a Z97 gaming 7 and I have 2x4gb of Kingston ram, and I want to get 16gb, but 2x4gb is much more expensive then 1x8gb atm. I was wondering if I could go with the single 1x8gb 1866 kingston ram. I will specifically get the 1x8gb Kingston HyperX Fury 1866 stick with 2x4gb Kingston HyperX Fury 1866 sticks.
