I have an older i7-4770 cpu which has a supported memory speed of 1600 mhz for ddr3 ram according to the intel website. I currently have 1600 mhz ram with 16gb but I was wondering if it was in any way possible to exceed that limit. Or could I overclock the spped of the ram to something like 2133 mhz? I'm not going to buy a new cpu unless it is impossible for me to get past 1600 mhz.
