Thank you very much for this link. I now understand how Ram memory actualy works.

Regarding real world performance, is there that much difference between 1333 and 1600? Or even the 1866Mhz?

If you want to read it without page breaks the print view is much better. 🙂

Nope, not that much.

Even in memory intensive tasks like gaming, the difference probably wouldn't be noticeable. I doubt you would even see a difference in FPS, as memory throughput is so high in the first place anyways.
