memory - Confusion regarding exact type and voltage of my laptop RAM module for upgrade

I have a Toshiba satellite laptop C50-A. I am thinking to add more RAM. It has currently a Micron DDR3-1600 Mhz PC3-12800 CL=11 Model 4KTF25664HZ-1G6E1 RAM Module. The confusion is this:
As I know from research DDR3 PC3 Ram runs on 1.5 v. But when I ran CPU-Z it shows my voltage is 1.35v not 1.5 v. And the type of RAM shown is DDR3 on CPUZ not DDR3L.
I ran a system scanner on crucial.com and it recommends an upgrade to DDR3L RAM running at 1.35v.
And RAMMON shows voltage as 1.5v, 1.3v and DDR3.
So my question is my RAM DDR3 running at 1.5 V or DDR3L running at 1.3v.
