(DIMMs) in the two DIMM sockets on the system board. Only non-error checking and
correction (non-ECC), 100-megahertz (MHz) DIMMs are supported. Purchasing mem-
ory upgrades from Dell Spare Parts ensures system compatibility; these upgrades are
also covered under your system warranty.
NOTE: Your computer is designed for peak performance with specific DIMMs that are
validated through rigorous testing. The system may not recognize other synchronous
