Dell Latitude E5500 upgrade kit

This 4 GB kit contains two 2 GB DDR2 SO-DIMMs built for the Dell Latitude E5500 notebook. Each module runs at 800 MHz with CL6 timings and 1.8 V unbuffered operation. The 200-pin form factor matches the factory slots exactly.

Fits two SO-DIMM slots

The pair occupies both memory sockets in the Latitude E5500, delivering the full 4 GB in dual-channel mode. No heat spreader is fitted, so clearance inside the slim chassis is not an issue. Installation requires only a small screwdriver and the service hatch.

Replaces slower or smaller DDR2 modules

Owners running a single 1 GB or 2 GB stick gain capacity and bandwidth in one step. The jump is worthwhile when the notebook still serves daily office tasks but feels constrained by the original memory configuration.

Questions about this item

Will the 1.8 V DDR2 800 modules throttle under sustained load?

The kit runs at standard 1.8 V with CL6 timing and no heat spreader, so thermals depend on the notebook's own airflow.

How much heat or noise does the 2Rx8 SODIMM add during all-day use?

Unbuffered DDR2 800 memory has no moving parts and draws minimal power, adding negligible heat and zero noise.

My Dell Latitude E5500 currently has two occupied slots — can I just add this 2 x 2 GB kit?

The E5500 supports a maximum of 8 GB across two sockets, so you must replace the existing modules rather than add to them.
