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 closest to the processor, before you install a module in the other connector. 1 2 matched pair of memory modules in DIMM connectors 1 and 2 NOTE: Memory purchased from Dell is covered under your computer warranty. 66 Removing and Installing Parts

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 closest to the
processor, before you install a module in the other connector.
NOTE:
Memory purchased from Dell is covered under your computer warranty.
