Memory Installation Guidelines

For information on the type of memory supported by your computer, look under "Memory" in the "Specifications" section.
NOTICE: Before you install new memory modules, download the most recent BIOS for your computer from the Dell Support website at
support.dell.com.

DDR Memory Overview

DDR memory modules should be installed in pairs of matched memory size, speed, and technology. 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: DDR400 memory runs at 333 MHz when configured with 533-MHz FSB processors.
NOTE: DDR333 memory runs at 320 MHz when configured with Pentium 4 800-MHz FSB processors.
NOTICE: Do not install ECC memory modules.
If you install a mixed pair of PC2700 (DDR 333-MHz) and PC3200 (DDR 400-MHz) memory, the modules function at the slowest speed installed.
l
Be sure to install a single memory module in DIMM1, the connector closest to the processor, before you install modules in the other connectors.
l
The actual speed of the SDRAM memory channel will depend on the speed of the processor's front side bus.
l
NOTE: Memory purchased from Dell is covered under your computer warranty.
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.
