1866mhz cl9 vs 2400mhz cl11 upgrade?

post #1 of 2
Thread Starter 
Hi all.

I'm thinking of upgrading my RAM from 16GB to 32GB, but in the process I would also like to gain some additional speed if that is possible ?
Currently I'm using 4x4GB G.Skill Ares 1866MHz CL9-10-9-28 2N 1.5v kit.

I have been looking at this memory kit since it's one of the cheapest with these specs I can find: G.Skill Ares 4x8GB 2400MHz CL11-13-13-31 2N 1.65v.


The system is a MSI X79A-GD45 Plus with Intel Core i7 4930K@4GHz.

Will there be any gain going from 1866Mhz to 2400MHz ? I have scrolled through tons of reivews but I haven't gotten a real answer as if it's noticable within daily work ?. I see differences in synthetic benchmarks. Also with gaming I have seen in some youtube video's from Digital Foundry that more MHz ram speed does increase FPS ?

I've also seen Linus' old video, where it's shown 1866mhz cl9 actually edging out 2400mzh cl11 ? It's really confusing ?. Maybe i should jeg get another 2x kits of 2x4gb 1866mhz ?

4sticks are faster than 2sticks

2400CL11 should be faster than 1866CL9
2.400 11 9.167 10.417 12.083
1.866 9 9.646 11.254 13.398

You should gain some fps
