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 "Memory" on page 127. 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 on the upper-right or upper-left corner of 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 configurations are: - A pair of matched memory modules installed in DIMM connectors 1 and 2 or - 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. • If you install mixed pairs of PC2-4300 (DDR2 533-MHz) and PC2-5300 (DDR2 667-MHz) memory, the modules function at the speed of the slowest module installed. • Be sure to install a single memory module in DIMM connector 1, the connector closest to the processor, before you install modules in any other connector.

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 "Memory" on page 127.
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 on the upper-right or upper-left corner of 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 configurations are:
–
A pair of matched memory modules installed in DIMM connectors 1 and 2
or
–
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.
•
If you install mixed pairs of PC2-4300 (DDR2 533-MHz) and PC2-5300 (DDR2 667-MHz) memory,
the modules function at the speed of the slowest module installed.
•
Be sure to install a single memory module in DIMM connector 1, the connector closest to the
processor, before you install modules in any other connector.
