My Sony Vaio SVE15133CN laptop has two ram slots. I have 2 gb ram(PC3-12800) installed(with voltage 1.50V). Now to upgrade my laptop I decided to add extra ram in another slot so If I put a RAM with same configurations(specs) as of my installed ram except the voltage(new ram voltage is 1.35V) then will it be good? Means will it run well without damaging my motherboard/laptop or is there is chance of damaging my laptop?
