Memory

You can increase your computer memory by installing memory modules on the system board. Your computer supports DDR2 memory. For additional information on the type of memory supported by your computer, see

the technical specifications for memory.

DDR2 Memory Overview

DDR2 memory modules should be installed in pairs of matched memory size and speed. If the DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance. See the label in the upper-right corner of the module to determine the module's capacity.

NOTE: The module's capacity label can also be seen in the upper-left corner of the module.

NOTE: Always install DDR2 memory modules in the order indicated on the system board.

The recommended memory configurations are:

A pair of matched memory modules installed in DIMM connectors 1 and 2

A pair of matched memory modules installed in DIMM connectors 1 and 2 and another matched pair installed in DIMM connectors 3 and 4

NOTICE: Do not install ECC memory modules.
