    I don't know what you compare it to but that is standard 1.5V RAM.
    Higher is 1.65 and more but I doubt there are many of those to go around for notebooks.

    There is only lower voltage RAM DDR3L with 1.25/.35V. That saves about as much energy as an HDD consumes which is not a great deal much. 1.5V is standard, 1.35V is the odd thing which is not supported by older CPUs. Buying lower voltage isn't a problem either though as they simple run in 1.5V if the CPU cannot handle the lower v.
