I have 1gb memory now. 2x512. I used the crucial scanner to figure out what I need. I want one more GB. They are showing the 2x512 as the reccomended upgrade, which costs $53. But I also noticed that there is 1gb of a single stick of 1gb for $42. Does it make a difference if I install one 1gb, or 2 512s? Are they just trying to get me to buy the more expensive package? It does say the 1gb is compatible, but reccomends the 2 sticks. It also says, "Your system requires that you install memory in pairs." I have 4 banks with 2 slots each. Does this mean that both slots in a bank have to be full? That I cant just place the 1gb in there instead of two 5x12s?
Here are the scan results and my setup http://www.crucial.com/systemscanner/viewscanbyid.aspx?id=19DB125931D926C3
