Kingston Hyperx Predator DDR4
  

DDR3 is being pushed beyond its capacity to meet this dynamic world, even with 1866MT/s and 2133MT/s speeds added and lower power DDR3U 1.25V, we are nearing the limits of its capabilities. Reduced power requirements aside, the demand for increased performance beyond 2133 motivated the transition to develop the next generation of memory.

DDR4's, the next generation in the family of memory. Kingston HyperX Predator is one of its kind.

Here are some detailed differences between Kingston HyperX Predator DDR4 and the DDR3 RAM's with its advantages

Re: Kingston Hyperx Predator DDR4

Are there any DDR4 RAM motherboards available in the market? What will be the cost of these RAM sticks? I was hoping that DDR4 memory's would be above 2400mhz in speed but it seems that it is kind of limited.
