Hi everyone, In my laptop (Asus ROG G752VM) I have DDR4-2400 16GB(2*8GB) of RAM, which are hidden inside laptop and not easy to be replaced(unless disassemble is required). However, I have another 2 empty slots for RAM which I can upgrade. I want to add 1 stick of 16GB, while my laptop can support totally of 64GB. But I don't know whether those 2*8GB RAM will work fine with 1 additional stick of 16GB? Or If I want to add 16GB then I need to buy another 2*8GB and put them in those 2 empty slots available?
