Kaby Lake CPUs and the associated Z270 motherboards can handle DDR4 frequencies higher than we have seen previously, good news for overclocking enthusiasts.  G.SKILL may be first past the post with new DIMMs, you can pick up their Trident Z DDR4-4266 DIMMs on NewEgg right now, $230 for a 16GB dual channel kit

This extra speed does come with an associated cost, they rate the voltage of these modules higher than you would expect from DDR4 at 1.4V as opposed to the 1.35 we are accustomed to and you should keep this in mind when shopping for a motherboard.  It will be interesting to see if these extremely high frequencies have any noticeable effect in gaming performance however they are already breaking records, 8 world records and 21 global first place records. 

You can see the various frequencies and timings currently available, expect to see more companies announcing new DIMMs very soon.
