CPU & Ram

Hi all,

I'm building a new system, and will be OC'ing my CPU for the first time.

Going with i5-3570k & GTX 690.. will be getting the EVO heatsink. MOBO Z77 family, TBD



I'm hoping to do a moderate overclock of the CPU. perhaps to 4.3 gHz or so? My question is, what speed of RAM should I get? I've read opposite facts, so I'm looking for some clarity on this. If MOBO ties into this also, please feel free to make a recommendation.


Thanks!
