I have a Compaq Presario R4000 laptop that has a total of 512mb of ddr 2700. When I opened the bottom cover all I can see I one of them. The other is under the keyboard. I am wanting to upgrade the laptop to at least a total of 1 gb. My question is which would be the better and which would be the easiest? I could just add a 1gb stick to the one that I can see without having to remove the keyboard or I can remove the keyboard and add 2-512 mb sticks. Will the performance be that much greater if I added 2-512 rather than just adding 1gb stick to the easier slot without having to remove the keyboard?
So to shorten this its : 2X512 ddr 2700 vs 1-256 ddr 2700 and 1- 1024mb ddr 2700
