1866MHz CL9 vs 2400MHz CL11 - upgrade ?

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 ?

Almost no difference. A tiny amount of games will show a bit of a difference though.

2400MHz ram is normally pretty cheap though, so I would grab that unless your going to save a noticeable amount of money by getting slow stuff

Yea the price is the same for 2133mhz cl10 as the 2400mhz cl11.
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 ?

Nah, 2400MHz cl11 is going to be faster than 1866MHz cl9 in pretty much everything.

But another matching set of the ram you have is probably not a bad idea, certainly cheaper and saves the hassle of selling your current stuff. Having 8 slots occupied might give you some issues, I dont know, I've never felt the need to do that.

why are you upgrading to 32GB anyway? If its for some niche purpose, then you are probably better of asking people who know about that thing, if its just for the hell of it / gaming then your wasting your money.

Yea, the question is just how much faster ?. I do a lot of gaming on this machine, but I also edit photos in Photoshop (uncompressed files) since photography is another hobby of mine.
Could be it's just a waste though... might just be the "upgrade itch" itching
