I was just told that any RAM above 1600Mhz is just a 1600Mhz pre-OC'd stick for the buyer. If this is true, then how much could I OC a stick of 1600Mhz RAM with it having the same speeds as a pre-OC'd stick of RAM? My motherboard supports RAM up to 2133Mhz, so would I be able to OC the 1600Mhz stick up to that speed? Also, I was about to buy the Ripjaws X series 8gb 1866Mhz RAM, and I'm basically asking if I were to buy the 1600Mhz stick, would it be as good as the ripjaws when I OC it to 1866Mhz?
