Overclocking RAM Speed

It means the board is able to run memory at those speeds even though Intel/AMD doesn't support those speeds officially.
And sure you can go higher, might run just like that or could need an increase in voltage or looser timings.
GOt my DDR3-1600 CL9 running at 2133 CL12, so the absolute timings stayed pretty much the same, but memory bandwith increased by around a third.

When a Motherboard lists a memory standard like this:

DDR4 3000+(OC)/ 2933(OC)/ 2800(OC)/ 2400(OC)/ 2133

What exactly does that mean? Does it give an option to overclock a DDR4 2133 stick to the above values?
Or do you actually need sticks rated for that number for it to work?
Also, does it matter what CPU you install in the motherboard?

Some CPU's are base clocked lower than what some RAM advertise as XMP. Will you still be able to clock this RAM higher than the CPU? I'm guessing it wouldn't make sense because you shouldn't be able to write faster than the CPU clock. Or would it "Turbo Boost" the RAM when it needs to?
