Yes, Here are some of thing we need to take care of 1. Needs to be from same generation, e.g. both rams needs to be from DDR4. 2. ram with lower clock will define the RAM Speed. let's say if there are two ram one running 3200 MHZ another 4800 MHz. then if we use both the 4800 MHZ ram will also run at lower clock. Will it work ? yes but there would be consequences as explained above.
