System-specific DDR2 SODIMM kit

This 4 GB kit from Computer Memory Solutions contains two 2 GB DDR2 800 MHz modules built to the PC2-6400 standard with CL6 timing and 1.8 V operation. The 200-pin SO-DIMM form factor is targeted at the Dell Latitude E5400 notebook and uses unbuffered, non-ECC chips in a 2Rx8 rank configuration.

Latitude E5400 owners only

The modules are validated for the Latitude E5400 and the Inspiron 14 (1420) platform, so buyers with those exact models can install them with confidence. Systems that require registered or ECC memory, a different pin count, or a faster DDR2 speed grade will not be compatible with this kit.

200-pin DDR2 SO-DIMM interface

The single specification that determines fit is the 200-pin DDR2 SO-DIMM interface running at 800 MHz (PC2-6400); only notebooks that accept this exact module type and speed can use the upgrade.
