I have a Dell 1545 Laptop running Windows 7 64bit OS. It came with 3GB of Ram. I recently upgraded to 4GB of ram thinking that it would increase performance. Alas, apparently I may have been wrong. Not only has performance remained virtually unchanged, The "MyComputer" properties still says I only have 3GB of ram.
Question1: What is the maximum amount of memory a Dell 1545 laptop can handle with it's 2 slots.
I thought that a 64-bit OS/System could handle more ram and hence improve performance. Is this so?
How can I make sure the the additional ram will improve performance.
