Installing memory

Your computer has four connectors for installing dual inline memory modules
(DIMMs) that provide up to a maximum of 4.0 GB of system memory.
System memory is divided into two channels (channel A and B). DIMM connectors
1 and 2 are designated as channel A, and DIMM connectors 3 and 4 are designated
as channel B. If DIMMs are present in both channels, your computer operates in
dual channel mode.
Your computer has either double data rate (DDR) or double data rate 2 (DDR2)
memory. The type of memory required depends on the system board that is
installed.
