I bought the DDR4 2400 8gb x2 at the same time I bought the I5 6600k. When I was looking on intel, it only shows like 1600/2133. a friend of mine said 2400 wouldn't work so tried taking it back to the store to get 2133 but was told it would work fine, so figured Id get other ppl's opinion. thank you
the motherboard Im using is MSI Z170I GAMING PRO AC Mini ITX LGA1151 Motherboard
