Best memory frequency for Gaming and Video Editing ?

Hello,

I am working on a new PC and i cant find out which RAM frequency is better for me.

My system :
CPU : Intel i7 4770-K
Mobo : Asus Maximus VI Formula
GPU : 2x EVGA 780 HydroCopper
PSU : Corsair AX1200i
WaterCooled .

PC is mainly for gaming and video editing. I want to OC my CPU as much as i can.
So what is the best ram frequency? I already have Corsair Vengeance Pro 16GB (2x8GB Kit) 1600Mhz CL9 for this build and i would like to stay with Corsair Vengeance Pro products, but today i saw an article where they said that higher frequency is better in video editing but have no impact in gaming. Everything would be fine and i would change mine 1600mhz RAM for 2400 Mhz as it is only 30 € more, but i saw article that says higher frequency is not good for OC´d i7 4770-K but at the same time i saw on formus that its good to have high frequency for -K editions procesors.

I am from Slovakia so i might have messed up my translations and i am just making things worse than they in reality are.

Here is the article about RAM and OCing CPU http://www.overclockers.com/3step-guide-to-overclock-intel-haswell. It says in STEP 2 :

With Haswell, that has all changed. Memory is a strange beast with Haswell. With your CPU clocked at stock, the Haswell IMC is a beast. Some chips will be able to do DDR3-3000+ without so much as batting an eye. Others not so much, but DDR3-2400 isn’t a stretch at all.

But – and this is a big, bold, italicized, very notable but - overclocking a Haswell CPU at the same time as overclocking the RAM will reduce your IMC’s ability to overclock or reduce your CPU’s ability to overclock. You have to choose one or the other, which is why the CPU came first in this guide. Core speed is king; remember that. If it comes down to choosing which to push farther, the CPU should always win in your calculations.

This will not only be heavily depending on the particular CPU you get, but also on the motherboard you choose. For instance, the Intel motherboard used for the Haswell review couldn’t run greater than DDR3-2133 at 4.8 GHz. However, using the same chip and the same memory, the ASUS Maximus VI Extreme for a future review had no problem running DDR3-2600 at 4.8 GHz.

Speaking of ASUS, let’s start with an example they gave. You might be able to run DDR3-2800 RAM and overclock your i7 4770K to 4.4 GHz. However, drop that down to DDR3-1600 or DDR3-1866 and that same CPU at the same voltage might be able to get to 4.6 GHz now. Everything in Haswell is linked. Reducing RAM speed on poor-to-pretty good chips will almost invariably increase the CPU’s ability to overclock.


So my priority is to overclock my processor as much as i can, use PC for Gaming to have as much FPS as i can get and Video Editing with good render times and i am not interested in overclocking RAM.

If i buy Corsair Vengeance Pro 2400Mhz will i be able to Overclock my CPU as much as i would be with 1600Mhz kit ? When i overclock my CPU will be my RAM working at 2400 Mhz ? What is better for me ?


I hope you guys can understand me. If there is anything that doesnt make any sense please tell me and i will try to explain it... somehow..

Thank you .

Using memory with the highest speed for video is always worth it, even it the cpu overclock cannot use it to the max, dropping the timings down after stable overclock, can improve performance or run it full speed for maximum memory bandwidth.

So should i go with 2400mhz ? Will i be able to achieve same CPU Overclock as with 1600 mhz or will it be bottlenecked? Does it have more Pros or Cons. Thats the main reason i am seeking help because i just dont understand it enough to make decision by myself .
As i said , on the first place is Performance in games , so i need to have overclocked CPU as much as i can , then comes video editing .

I would go 2400, o/c the crap out of the chip and then drop the timings.
