Can I use different RAM sticks?

Hi!
I built my gaming PC in late 2012, and have since upgraded it's graphics card.
Now it's holding up pretty well in all games, but I am beginning to feel like I need to add more RAM, since I only have 8Gb at the moment.

So right no I have two sticks of Kingston 4GB HyperX Fury, DDR3 1600MHz, CL10, 1.5V RAM.
And I'm wondering If I want to add more, does it have to be those exact sticks? Or is it enough if the voltage and MHZ and DDR is the same? So I could add let's say Crucial 8GB (1 x 8GB) Ballistix Tactical, DDR3 1600MHz, CL8, 1.5V RAM?

Adding more memory, the new memory doesn't necessarily have to be the same (make and part number) as the existing memory. The memory parameters (capacity, voltage, frequency, timings) should be the same as far as possible to maximize available memory band width.

However! There is a risk of inter-module incompatibility due to variations in memory module characteristics (even for modules with the same make and part number). In this case it might require having to try other memory modules as well until a compatible combination is found. This process might take time and cost more in the end.

It is usually recommended getting a dual channel memory kit (2 x 8 GB for this case here) as the memory modules have been tested for and guaranteed to be compatible with each other. The existing memory (two Kingston 4 GB modules) could be kept as back up or sold.

Sorry for not replying sooner, been "busy" with the holidays. But anyways thanks for the answer. I guess the smartest thing to do is to just get two 8 GB ram sticks.

Thanks for the reply!
