• DIMM connectors must be populated in numerical order beginning with
connector DIMM_1 and then connector DIMM_2.
If a single DIMM is installed, you must install it in connector DIMM_1.
For best performance, memory modules should be installed in pairs of
matched memory size, speed, and technology. If the memory modules are not
installed in matched pairs, the computer will operate, but with a slight
reduction in performance. (See the label on the module to determine the
module’s capacity.) For example, if you install a mixed pair of DDR2
553-MHz and DDR2 667-MHz and 800 MHz memory, the modules function
at the slowest speed installed.
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. You should install your original memory modules in pairs either in:
DIMM connectors 1 and 3 or DIMM connectors 2 and 4 (not applicable for
Inspiron 530b/530d).
NOTE:
Memory purchased from Dell is covered under your computer warranty.
1 Pair A: matched pair of memory
modules in connector DIMM_1
