Support website at support.dell.com.
DDR2 Memory Overview
Dual-channel 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 in the upper-right 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 memory module installed in connector DIMM1
or
A pair of matched memory modules installed in connectors DIMM1 and DIMM2
or
A pair of matched memory modules installed in connectors DIMM1 and DIMM2 and another matched pair
installed in connectors DIMM3 and DIMM4
NOTICE:
Do not install ECC memory modules. Doing so may cause the system not to boot or affect performance.
Be sure to install a single memory module in DIMM1, the connector closest to the processor, before you install modules in the
other connectors.
NOTE:
The small form-factor computer has two slots which are considered an interleaved pair.
