Hi, I'm using Acer Aspire 5750g laptop for almost 5 years now. About 4 month ago I had bought a 8gb ram ddr3 1600 1.35v (low voltage) to replace one of my ram and now it became 10gb (8gb + 2gb).

Unfortunately, my mistake are, I didn't check my other ram (originally come with the laptop) are ddr3 1333 1.5v when I buy the 8gb module and I just realize my mistake when I install CPU-Z.

So my questions is, is it ok I'm using different voltage and speed for my ram or do I must change my old ram and buy a new one using same speed and voltage with my new ram?
