I have G75VW-NS72, wondering if 1.35v RAM in 2 of the 4 slots is safe, since the default RAM is 1.50V?

As I mentioned, I have a G75VW-NS72 which currently has 16GB of DDR3 1600 1.50v (4 sticks x 4GB), but only 2 of the sticks are accessible. Which is why I'm wondering, if I replace the 2 easily accessible sticks with two 8GB DDR3 1600 1.35v will it be okay?

Well that's disappointing, I could swear that it was 32GB... but it has been a few years since I bought it so I could be mixed up.
