my system is running with 4*4 gb of ram at 1600mhz .. i want to use 2*8 gb @1866mhz instead .. just wondering if i have to overclock my system in order to make it possible use that or just simply swap and replace the memory kit and keep every thing default???
core i7 4770k .. z97 gaming 5 by MSI ,, MSI gtx 780ti
