RAM's influence in overclocking CPU

post #1 of 5
Thread Starter 
Noob question here, how does my RAM timings etc affect the OC potential of my CPU? Do tighter timings or higher ram speeds give my CPU higher OC potential?

I know on Nehalem it actually strains the memory controller making it much more difficult to hold a stable Overclock. However cant say for sandybridge. Just not sure if the rule still applies.

Ill be here to learn as well!

on 1155 you can OC your RAM and your RAM settings won't mean much. However if your voltage is anything above 1.5v, then it will put more load on the IMC and you will only have to bump up your CPU vcore a smidgen. It is not like it will go completely unstable like nehalem.

That being said, anything over 1.65, and you will start running into a lot of stability issues.

So voltage taxes the IMC, but how does ram timings and speed affect the cpu clock? I have read that tighter timings tax the cpu less, which higher speeds give it better OC potential?

Short answer is it doesn't. Long answer is it ONLY matters if you have an older CPU. Sandy bridge chips and above only show signs of CPU fatigue when you OC your ram to insane speeds. Simply changing your timings or turning your frequency up a notch or two isn't going to effect your CPU OC.
