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.
Note: Addressable memory might be less than total supported memory.
System memory is divided into two channels (channel A and B). Memory
connectors 1 and 2 are channel A, and memory connectors 3 and 4 are channel B.
If memory modules 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 in your computer.
