My laptop is an ASUS n53J and it has 4 gig of ram (2x2GB). It has 4 slots. I want to replace the 4gb of ram with 2x4GB ram. But I was thinking of not removing the 4GB ram and add another 8GB for a total of 12GB of ram. The configuration would be 2x2GB and 2x4GB.
Will it work or I am better having 2x4GB running at dual channel?
