Did you update your bios?
I think this might be the new intel crappy limitation to 2666mhz on all i5 non K parts.

Make sure you installed the modules in Slot A2 and B2 for dual channel mode. [CPU Socket] |A1|A2|B1|B2|

Why did you buy 2400 ram when you have a Z series motherboard that officially supports up to 3200 ram? 3200 is usually not much more expensive, but can give a 15-20% or higher performance boost over 2133-2400.
