Memory
If your computer only has one memory module installed on the system board, you can increase your
computer memory by installing an additional memory module.
Your computer supports DDR2 memory. For additional information on the type of memory supported by
your computer, see "Specifications" on page 87.
DDR2 Memory Overview
DDR2 memory modules should be installed in pairs of matched memory size, speed, and technology. 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 on the module to determine the module’s capacity.
NOTE:
Always install DDR2 memory modules in the order indicated on the system board.
The recommended memory configuration consists of a pair of matched memory modules installed in
DIMM connectors 1 and 2
NOTICE:
Do not install ECC or buffered memory modules. Only unbuffered, non-ECC memory is supported.
•
If you install mixed pairs of DDR2 400-MHz (PC2-3200) and DDR2 533-MHz (PC2-4300) memory,
the modules function at the slower installed speed.
•
Be sure to install a single memory module in DIMM connector 1, the connector closer to the processor,
before you install a module in the other connector.
