I was referencing you build, and no B150 or H110 cannot operate at speeds greater than 2133MHz, the 2400MHz will drop down but if the OP decides in the future to upgrade to a Z170 motherboard, they get the benefit of being able to use 2400MHz without having to buy higher later.
I create parts lists that are future-minded. Some parts will remain, others get phased out. It's about lowering and spreading the cost.
