Confused when it comes to low voltage ram support

Is it dependent on the CPU or the mobo?
I am getting:
- MSI B150M Mortar
- i3-6100

The intel website for the 6100 says:
"Memory Types DDR4-1866/2133, DDR3L-1333/1600 @ 1.35V"

The motherboard says it supports DDR4 ram up to 2133Mhz, nothing about the voltage.

I read that having a ram stick that needs less voltage to run at the same speed (2133Mhz) makes a stick more stable, and last longer.

I really just want to know if I get a 2133Mhz that runs at 1.2v, will my system work with no problems?
Also, if I get a 2400Mhz, will I need to mess with the XMP profile, whatever that is?

Thank you very much for reading through my beginner questions. I do all my research to avoid bothering others, but this I simpy cannot figure out...

    DDR3L support is motherboard dependent since the slots for DDR3L and DDR4 are different. Typical DDR3 is 1.5V, DDR3L is 1.35V. I would just ignore DDR3L if I were you.

    DDR2400 should be fine. It will run at 2133, 2400 is the MAX speed it has been tested.

    What about the voltage? Is it possible i'll have any problem for running ddr4 at 1.2v instead of 1.35v?
  3. The voltage of the RAM should be listed when you purchase it. I don't believe you will have problems.
