Yes just make sure you have them in the white slots.
What are all those white and blue slots mean. I don't understand.
I'm using 3*2gb kit. If i combine them with new modules i keep using them. (e.g. 3 white slots 3*2gb old ram / 3 blue slots 3*4gb new ram or = 18gb
3 white slots 3*2gb old ram / 2 blue slots 2*8gb ram = 22 gb)
Or all the ram size must be same in order to use them?
