Memory
You can increase your computer memory by installing memory modules on the system board. For information on the type of memory supported by your computer, see "Memory."
NOTE: DDR 333 memory operates at 320 MHz when used with an 800-MHz front-side bus.
DDR Memory Overview
DDR memory modules should be installed in pairs of matched memory size. This means that if you purchased your computer with 128 MB of memory installed and you want to add another 128 MB of memory, you should install it in the appropriate connector. If the DDR memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.
NOTE: Always install DDR memory modules in the order indicated on the system board.
The recommended memory configurations are:
Install a pair of matched memory modules in connectors DIMM1 and DIMM2.
or
Install a pair of matched memory modules in connectors DIMM1 and DIMM2 and another matched pair in connectors DIMM3 and DIMM4.
Do not install ECC memory modules.
If you install mixed pairs PC2700 (DDR 333-MHz) and PC3200 (DDR 400-MHz) memory, the modules function at the slowest speed installed.
Be sure to install a single memory module in DIMM 1 or the connector closest to the processor before you install modules in the other connectors.
Memory Installation Guidelines
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. You should install your original memory modules in pairs either in
connectors DIMM1 and DIMM2 or connectors DIMM3 and DIMM4. If possible, do not pair an
original memory module with a new memory module. Otherwise, your computer may not
function at optimal performance.
NOTE: Memory purchased from Dell is covered under your computer warranty.
