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, double data rate synchronous dynamic random access memory (DDR SDRAM).

vUse 128 MB, 256 MB, 512 MB or 1.0 GB DIMMs in any combination.

vDIMMs are 38.1 mm (1.5 inches) in height.

Note: Only DDR SDRAM DIMMs can be used.
