Which of These Will Overclock?

So I'm going to get a i5 4690K for my CPU, a Motherboard that says "2133(OC)/1866(OC)/1600/1333 on its "Memory Standard" (I don't know what it means) and a Graphics Card that is Pre-Overclocked

MOBO: ASRock Z97

Memory: G.Skill Sniper DDR3 1866

Graphics Card: MSI R9 280

My question is which of these will automatically overclock?
Since the Graphics Card comes pre-overclocked, does this mean the rest of the components (mobo, CPU, etc) will start automatically overclocking too?

The Memory is DDR3-1866, so the motherboard will overclock automatically?

My preference is not to overclock any of these because I'm worried about instability

Nothing will automatically overclock.

The graphics card is factory overclocked, which just means it will run at higher clocks than the standard AMD specifies. You can still do "real" overclocking beyond that. And the CPU can be overclocked separately, and hte memory for that matter. But all of it will require your intervention.

The memory will default to DDR3-1333, to run at 1866 you will have to enable XMP and pick the 1866 profile. It's only overclocking if you go beyond 1866.

default to 1333? how come not 1600? I thought the highest the motherboard can go is 1600MHz without overclocking

Most DDR3 defaults to 1333 just to ensure the system will boot properly the first time.

1866 is what the memory kit is rated for, so setting it to 1866 isn't overclocking the memory. But the memory controller in the CPU is technically only rated for up to 1600, so 1866 means the memory controller will technically be overclocked. The motherboard doesn't really factor into it, it's just a matter of what settings the board has enabled - motherboards that don't allow CPU or memory overclocking will simply not permit you to set higher memory speeds than 1600.

so in order to not overclock anything but still get the maximum frequency (MHz), i would have to get a DDR3-1600 Memory, right?

Well, the 1866 kit can be set to 1600 too. But yeah if you're going to run it at 1600 then there's at least no reason to pay extra for 1866 (but if it doesn't cost more than 1600 kits then whatever).

This particular type of overclocking is really very trivial. The memory controller can easily handle 1866 and way higher too. They can go beyond 3000, so 1866 is very comfortable.
