Does voltage gives problem in installing memory?

[Camaross1220]

hello there,im having a notebook which is i was having problem in installing ram on it...The board supports ddr3 ram with 1600mhz and i also used those but after i installed,my ram shows on spd tab but not in windows/bios...So,i have checked whats the problem/differences,i came up with voltage which my ram on board using 1.35v and the ram i bought was 1.5v...Does this difference is matter and how to change voltage from 1.5v to 1.35v??

No, you cannot run 1.5V RAMs in laptop mobos designed for running 1.35V RAMs. Also, you cannot lower the voltage from 1.5V to 1.35V. I am sorry to say you cannot use the 1.5V RAM.

Appears you are adding to existing DRAM and the two aren't compatible, most laptops have a locked BIOS so you can't adjust voltages/timings and the like
