Installing a memory module

Your computer has four connectors for installing dual inline memory modules 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 module connectors 1 and 2 are designated as channel A, and memory module connectors 3 and 4 are designated as 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.
