2400mhz or 1600mhz

TheGameManiac · Sep 19, 2013

So, I decided to go with either G.Skill ripjaws 2x4gb 1600mhz or should i get the Kingston HyperX 2x4gb 2400mhz 20$ more or even the Corsair Vengeance 2x4gb 1866 for the same price as ripjaws.

i7 4770k
Asus maximus VI hero
GTX 660ti(yeah,yeah i know.Old card..When new AMD series coems out il be switching for a 600+$ card.)

1 more thing that concerns me.Intel OFFICIAL support is for DDR3-1600, if i put in the 2400mhz ram without changing bios freq. Will they run at 1600 and will they be equally efficiant as normal 1600 ram.And do i lose insurance on the i7 if I put in the 2400mhz ram and change bios frequency to support it.

IMO, there isnt really much diference betwen 1600ram and higher, the usual recommendation is that if your not paying more for it, then it wont hurt. But if the sticks are more expensive, than allocate the money smowere else.

I believe that puting a 2400 ram were the "max" is 1600 will just make it run at 1600.

2400 ram is really slower ram that can be overclocked to run at 2400.
You will have to set the ram to higher voltages to overclock it to 2400.
It will probably work, and so long as the ram voltage does not exceed 1.65v you should not have a cpu damage issue.

But...

There is really little real value in changing. Read this article:

Intel rates their CPUs to native MC support, here it's 1600 and the rating is for stock speed as Intel doesn't advocate OCing CPUs (officially)---the Haswell K models can easily run much higher freq DRAM generally with a 4770K to 2800+ and the 4670K to 2666 or better....

Contrary to Geofelt's comment DRAM is sold as to what it's rated, i.e. 2400 sticks are sold to run at 2400, it's NOT slower DRAM that you OC, it's designed and made to run at 2400. you are not OCing it - however it may require an OC of the CPU to run at it's spec speed as the stock speed of the CPU and MC (memory controller)....If you look at DRAM freqs in a mobos specs you often see a "(OC)" next to freqs 1866 and up - which actually means an OC of the CPU may be required to run at that freq
