Dell™Dimension™C521ServiceManual
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.

DDR2 Memory Overview
Your computer has a minimum memory configuration of one DDR2 memory module. This memory module must be installed in DIMM1. If two or more DDR2
memory modules are installed, they 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.
The recommended memory configurations are:
lA memory module installed in connector DIMM1
lA pair of matched memory modules installed in connectors DIMM1 and DIMM2
lA pair of matched memory modules installed in connectors DIMM1 and DIMM2 and another matched pair installed in connectors DIMM3 and DIMM4
lIf you install mixed pairs of DDR2 533-MHz (PC2-4300) and DDR2 667-MHz (PC2-5400) memory, the modules function at the slower installed speed.
Be sure to populate the memory modules in order starting with DIMM1, the connector closest to the edge of the system board, before you install modules in
the other connectors.


NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that
you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module.
Otherwise, your computer may not start properly.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
