Effects of OverClocking Memory on CPU OverClock

[UaVaj]

obviously this is a lottery question, however in general.

how much cpu overclock do you give up when u overclock memory?

processor in question is 4930k.

 

[schmuckley]

none really
Get the CPU OC 1st,then see what the RAM will do.

That basically.

Memory overclocking used to have a pretty big impact on core overclocking, but that has changed quite a lot over the years. One still afffects the other, but not nearly to the same extent. Just don't go too crazy with the RAM clocks because it can cause instabilities that are very hard to diagnose (And can look like CPU instability when really it's the memory that's unstable), even harder to fix and they aren't even worth it in the first place. Since we're talking about DDR3, I'd say do what I did. I got a 2133MHz CL11 kit and bumped it to 2200MHz CL9. Performance did go up ever so slightly, it's stable and didn't affect my core OC. And I'm a happy camper.

found the answer here.

here is the link if anyone need it.

Thought you'd all ready gotten an answer

Timings matter also, of course, I tend to run mine slower and tighter myself.

 

[UaVaj]

yes. timing does matter. in a big way.

example. 1866 CL8 is faster overall than 2133 CL10.
another example. 1866 CL8 is faster than 2400 CL11 in random access, but slower in sequential access.



bottom line is. there no need to add stress the IMC by going with faster memory until timing is exhausted.

Agreed ever since the memory controller was moved off the boards and onto the cpu's you don't see the huge jumps in memory performance anymore.

And since most software will be running into Cpu bottlenecks before memory that is where you always want to be pushing.
