Been doing some research, since i'm planning to get a I5 4670k, with a gigabyte z87 ud4h and a G.Skill Ares DDR3 2133 8GB (4x2), on the intel site it says i5 can only go up to 1600 as a max, unless you have xmp/amp support on your Mobo. The problem now is apparently Haswell don't support xmp as far as memory control goes, so i was wondering if i should even bother with 2133, and if i do have to have a 1600 then is there a possibility to increase the Mhz? apparently 1600 will not overclock to anything.
