For the past week or so I wanted to add some more RAM to my system. At the moment I have Corsair Vengeance LPX 16GB (2x8GB) DDR4 3000MHz. If I bought the same exact RAM and put it into my system would it work? I have heard adding RAM with two kits at different time doesn't work sometimes. My current RAM was bought around four months ago. Just wanted to know if this is safe.

msi z270 sli plus

16gb ram 3000mhz
