3200MHz vs 2400MHz DDR4

[mtty34]

Title says it; will be using 4x4gb sticks. Primary usage is gaming. 2400MHz is cheaper but the extra £30 doesn't bother me if it is beneficial in the long term.

What CPU

 

Id go 2x8GB if your on lga 115X, its faster and can be upgraded.

 

The speed won't make a difference(less than 2%, less in games)

Why? I won't need 32gb of RAM at any point.

definitely depends on if your motherboard and cpu can handle memory at that speed. but for the extra few bucks 3200mz doesn't sound badif your hardware can support it. there are also motherboards that support quad channel (which would REALLY increase your speed, alot more than just a mere 800mhz)

2 sticks is faster on 115X sockets, and OC's more

 

You might need 32gb, its always nice to have more ram.

I7 6700K and Asus Z170 ROG Maximus VIII Hero.

If you are looking for 0.05% to 0.10% performance increase for 30$ then go for it. There are benchmarks online that prove my theory. Someone benched it with 6700K in Cinebench 15 and the difference was like 1022 points with 2400Mhz and 1035 points with 3200Mhz RAM. I personally have 3200Mhz and I see no difference.

6700k and that motherboard good. higher speed ram wont make a difference unless you are video encoding or something, but for the few extra bucks it might be worth it for the bragging rights

You also have quad channel RAM, speeds tend to make less of a difference at that point.  There's also benchmarks online that show minimum FPS being a lot higher on higher RAM speeds, if you want to make that point

Not true. I used to have 32GB in dual channel. 16GB x 2. No difference.

So you did in depth testing before and after, and compared both?  I'm not trying to say there is some huge massive difference, but there's benchmarks ALL over the place showing there is a difference. 

 

Everything suggests that any CPU intensive scenario should slightly benefit from faster RAM speeds, and that in theory it's supposed to help with minimum frame rates. I believe there's some benchmarks out that show that too.

 

Here's one with graphs, FPS counters and a bunch of games tested:

I have tested.
