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.

When installing DIMMs, the following rules apply:

vSystem memory is divided into two channels (channel A and B). DIMM connectors 1 and 2 are channel A, and DIMM connectors 3 and 4 are channel B.

vIf DIMM connectors 1 and 3 (or 2 and 4) are filled with the same technology and size of memory, the system operates in dual channel mode.

vUse 2.5 V, 184-pin, 333 MHz double data rate synchronous dynamic random access memory (DDR SDRAM).

vUse 128 MB, 256 MB, 512 MB or 1 GB (when available) DIMMs in any combination.

vDIMMs are 25.4 mm (1.0 inch) in height.

Note: Only DDR SDRAM DIMMs can be used.
