Understanding the Memory Types for a CPU

So I was trying to design a build to use for video editing and a badass gaming experience. After choosing my CPU the I7 5930K for the 6 Cores and 12 threads, I needed RAM for high speeds and I realize the I7 5930K uses only X99 Mobos which supports DDR 4 so I decided with the Corsair DDR4-2800. Then looking on intels website I see it says Memory Types: DDR4 1333/1600/2133.
So what does that mean you can only use those individual speeds: 1333, 1600, or 2133. What happens if i choose something over, will it fail or slow down the speed to 2133. Is there any way to go above the speed of 2133 if i have something above it like 2800 or should I try 2300.
I looked at some completed builds for the X99 Mobo type and some used 2133, 2300, and 2800 so I really have no clue. If there is already a thread about this please direct me towards that thread or if there is not please answer.
Thanks

The CPU is 'rated' to 2133, you can still run higher freqs but they may require a slight OC of the MC or CPU itself, most 5930K's can run 2400 at stock, for 2666 it may require a small OC of the CPU or additional voltage to the MC (memory controller)
Generally, those are the speeds that Intel recommends because they're the standard speeds. Take a look at the i7-4790k for example, it shows that the memory type is DDR3 1333/1600. There are people on this forum that say it can run at 2133. I've gotten my 4790k to run 2400 at stock with no problems. So when Intel lists DDR4 1333/1600/2133 for memory type, it should just be what they recommend.
