Quad or Dual channel RAM?

Hey

 

I have a question about if I should buy 4*4gb or 2*8gb RAM? Because on the Asus site for the motherboard it says "Dual Channel Memory Architecture".

 

The RAM is the "Corsair Vengeance LPX DDR4 3000MHz"
The Motherboard is "ASUS ROG STRIX Z370-H Gaming"

 

Thanks in advance

You can go either, if the board has 4 dimm slots, but you will likely find 2*8 a better option to be honest, usually for stability & OC potential if youre going to do that.

Hi,

 

2 sticks of ram are better in your case, less stress on the memory controller and free slots for an upgrade later on.

This. More memory sticks just help with productive programs (aka video render and 3d modeling), at gaming the dual or quad doesn't help more than 2%.

Im gonna use it for gaming but also a lot of video/picture rendering in fx Photoshop and Premiere - So would you say go with the quad for that?

Socket 1151 (new and old) uses dual channel memory, I would get 2x8 GB to be able to throw in more RAM in the future

But, 2x8gb is 16gb and that should be enough for any build?  then there should not be an need to upgrade in the furture (or at least the next 2 years)? But is there any performance different from the quad vs dual? Such af we see in the picture?

The motherboard supports dual channel, but has 4 dimm slots. It doesn't support quad channel. Two dimm slots go to one memory channel, and the other two go to the other memory channel.

Does it mean that it can do dual channel * 2?

Basically this, running four sticks of memory is just dual channel twice.

Quad channel can only be ran on machines that suported (X99 and such), if you put 4 sticks on socket 1151 it won't run on quad channel, it will be dual channel with 2 sticks per channel
