m7com,

Depending on your system, the installed memory could be low voltage memory. I am not able to tell what system the E15 is, if you could be a little more model specific. Once I have that information I can tell you whether or not the memory is low voltage or not.

What is the memory that you purchased and installed in the notebook?

This notebook uses low voltage DDR3L (1.35V) memory, the memory that you are trying to use is regular DDR3 (1.5V) memory.

So if i wont to purchase i new RAM it must be a low voltage DDR3L and it will work perfectly, Right?

and The Q here that how i can tell if The RAM is DDR3L or not?

For example this is The RAM That my ntebook use it :

m7com,

Do you see that "L" where it says PC3L, that means it is low voltage and as long as the memory you purchase matches that criteria you will be good. When searching for memory there is usually a filter for voltage, and if so, put a check in the box for 1.35V.
