Compatible Dell Latitude E5400 Upgrade

This 2GB DDR2 SO-DIMM is built specifically for the Dell Latitude E5400 notebook. It uses a 200-pin form factor and operates at 800 MHz with a CL6 latency timing of 6-6-6. The module runs at the standard 1.8V voltage for DDR2 technology. It arrives as a single unbuffered, non-ECC stick using major brand chips.

Not for ECC or Higher Density Needs

Buyers whose systems require error-correcting code memory cannot use this non-ECC module. Notebooks limited to a single memory slot will not benefit from the 2Rx8 dual-rank organisation if the chipset expects single-rank parts. The 2GB capacity also leaves no room for expansion on single-slot platforms.

DDR2 800MHz 200-Pin Specification

The decisive specification is the DDR2 800 (PC2 6400) 200-pin SO-DIMM interface. Only notebooks designed for this exact DDR2 generation and pin count will accept the module. Systems built for any other memory generation or pin layout are physically and electrically incompatible.

Questions about this item

Will this 200-pin DDR2 SODIMM work in the second slot of my Dell Latitude E5400 alongside the original module?

The Dell Latitude E5400 has two SODIMM sockets supporting up to 8GB total, so this 2GB stick can occupy the free slot beside your existing memory.

How can I verify the CL6 6-6-6 timings are active after installing the module?

Open CPU-Z or the BIOS memory tab; the SPD table should show DDR2-800 at CL6 with 6-6-6 timings at 1.8V.

Does the package include only the single 2GB SODIMM or are screws and tools supplied?

The box contains one 2GB DDR2 SODIMM stick; no screws, tools or additional cables are included.
