Targeted Memory Upgrade

This 4 GB DDR3 SODIMM is built specifically for the Dell Inspiron 14 3421 laptop. It provides a direct replacement or capacity increase for owners of that model who need more memory for everyday multitasking. The module arrives new and ready to install without configuration changes.

Build Integration

The 204-pin unbuffered non-ECC stick plugs into the standard DDR3 SO-DIMM slot found in the compatible notebook. It operates at the JEDEC-standard 1.5 V, so the existing memory controller handles it without BIOS adjustments. Adding this module frees up system resources previously constrained by lower capacity.

Thermals and Power

With no heat spreader and a low 1.5 V operating voltage, the module runs cool inside the tight chassis of a 14-inch ultrabook. Passive airflow from the laptop's existing fan is sufficient; no additional cooling is required. Power draw remains minimal, preserving battery life during normal workloads.

Questions about this item

How does the CL11 latency affect performance during sustained workloads?

CL11 is the CAS latency rating at DDR3 1600 speed; lower latency can improve responsiveness in memory-intensive tasks.

Does the 1.5V DDR3 module run hot or draw more power under continuous use?

The module operates at standard 1.5V without a heat spreader; typical DDR3 SODIMMs stay within normal thermal limits for laptop use.

Will this 204-pin SODIMM fit my Dell Inspiron 14 3421 without any other parts?

Yes, it is a direct 204-pin DDR3 SODIMM upgrade for the Inspiron 14 3421; no additional components are required.
