Direct-fit upgrade for Dell Inspiron E1405

This 64MB DDR2 SO-DIMM is built specifically for the Dell Inspiron E1405 notebook. It arrives as a single 200-pin module rated at 667 MHz with CL5 timing and 1.8 V operation. The unbuffered, non-ECC design matches the original factory specification for drop-in installation.

Capacity limited to 64MB per module

Each stick provides only 64MB, so the notebook’s two slots top out at a total of 128MB. Systems that require 256MB or more cannot reach that amount with this part. Buyers who need more storage per slot must choose a different module.

Steady throughput at rated speed

Under sustained load the memory runs continuously at 667 MHz with 5-5-5 timings and no heat spreader. The major-brand chipset maintains the specified latency without throttling. Voltage stays at 1.8 V throughout extended sessions.
