RAM Voltage Help

[Viet Vo]

Hello, when I look at parts list I noticed that some RAM has 1.5v, 1.35v or 1.65v listed next to it. I was wondering what is the significance of this? I will be using an i5 4440 and an Asrock b85m pro4. I was thinking of getting a 1.35v because they seem cheaper.

Lower voltage is good for reduced power consumption and less stress on the CPU IMC (Integrated Memory Controller) which will result in slightly cooler CPU temp and, maybe, longer CPU life. The DIMMs will also run slightly cooler resulting in lower case temp.

EDIT: The above assumes that you will not suffer reduced memory performance due to lower RAM frequency or slower timings. Always compare 'apples to apples' when selecting RAM.
