Best RAM setup? 2x4 4x8 etc

[eddywatson]

Hello

I am planning on getting 32gig of RAM for a new gaming rig. and there is different setups: 2x4 2x8 etc...

is there any difference between the setup? as long as theres a total of 32 will there be a difference in performance?

4x8 is all I can do anyways I think right?

But lets say as an example I wanted 16gig I could do:
2x8
or
4x4

which would be better? or is there NO difference at all its just down to what your mother board can handle?

Also Ive seen 2133MHz, 2666MHz and 3000MHz what is the difference. will 3000MHz give more power?

Thank you

Depends on the board.

For X99 you would want to use quad kits as the cpu has a quad channel memory controller.

Z170 is dual channel, but you can use quad channel kits just fine and they will work in dual channel mode as two sticks per channel.

Is bank interleave still a thing?

Dont believe so.

Or its all done without any fiddling needed.
