Memory Slot Advice ?

[MacRumorUser]

So I have ordered some more memory today and need to know which slot to place the memory into for maximum peformance of my system.

At the moment it has 3gb


2 x 512mb slot 1/2 riser a
2 x 1gb slot 1/2 riser b


I have ordered 2 x 2gb taking my total to 7gb
But where to put the 2x2gb ??


Should it go it Riser A / B 1/2 ? 3/4 ? :confused: Just confused at this stage so any help will be appreciated.
