Overclocking CPU (4770k) advice regarding RAM!

I'm about to try my first overclock in a couple of days, just as soon as my arctic silver arrives, and I can clean my CPU of the stock thermal compound that came with my H105, as well as dismantle my PC, dust it all off, and reassemble all sparkly clean and air flow maximised!

Anyway... I've always shied away from OC'in but want to try it finally, but it means having to learn everything.

I get the CPU side of it, and how to simply increase multiplier, then voltage, bit by bit, until I find the sweet spot and the system passes stability tests, etc. I get using override mode on the voltage setting, then switching to adaptive when done, and so on.

The only thing I can't seem to find an answer for is why you have to mess with RAM speeds. From my limited, noob knowledge, I thought RAM speed was affected by the CPU's base clock, but since it's only the CPU multiplier that gets a bump, the base clock stays the same.

What's more, I've seen YouTube guides where people mess with RAM speeds during their CPU OC, but others where the RAM is not touched at all. This just makes it extra confusing.

Can somebody please explain, as detailed as they can be bothered, the dynamic between CPU and RAM when OC'in please? Any particular area I need to be mindful of in RAM when I attempt my CPU overclock?

Thanks!

You don't, simply set your DRAM (if 1600 or better it's as easy as enabling XMP and selecting profile 1). the can play with the CPU OC, as long as you are OCing the CPU via the multiplier they don't overlap - if you start playing with the BCLK then they will ;)

Thank you, sir. I am steadily learning about this wonderful world of tech, but it gets confusing. Glad I got the idea behind RAM and CPU right and wasn't completely off.
