You mean RAM sticks?
NEVER use mixed RAM. NEVER means NEVER.
Your computer does not need 16GB of RAM to work. But if you think it would be cool to have 16GB, dump all the existing RAM and get a 16GB KIT.
KIT = A bunch of RAM sticks tested to work together.
If you add two more newly purchased Samsung RAM and add it up with the existing Samsung RAM, it will still be mixed RAM.
