This is a dumb question and I'm a bit ashamed of having to ask but it's the first time I stumbled across it.
Let's say I have an i7 5960X with support for DDR4 1333/1600/2133, an ASUS X99E-WS which supports up to DDR4 3200MHz and put DDR4 3600MHz RAM into it. To me the CPU then is the bottleneck. Does the RAM clock down to 2133MHz? Is there a way to have the RAM run faster (BCLK OC?)?
What happens if I'd put it into a Mainboard that supports 1333MHz at max? I know this is non-existent but just for illustration.
Is the entire system running at the speed of its slowest component?
