Targeted Dell Inspiron 14R (5421) upgrade

This 8 GB kit contains two 4 GB DDR3L SODIMM modules rated at 1600 MHz with CL11 timings and 1.35 V operation. It is built specifically for the Dell Inspiron 14R (5421) notebook and installs in the two available slots.

Suits owners restoring stock capacity.

The kit matches the system’s maximum supported memory of 8 GB and must be installed as a matched pair for dual-channel operation. Buyers who want more than 8 GB total capacity cannot use this platform.

204-pin DDR3L 1600 CL11 1.35 V specification

The modules use the 204-pin DDR3L interface at 1600 MHz with 11-11-11 latency and 1.35 V voltage. A notebook requiring DDR3 at 1.5 V or a different pin count will not accept these sticks.

Questions about this item

Does the Dell Inspiron 14R (5421) need a 64-bit operating system to use all 8GB?

Yes, the maximum 8GB configuration requires a 64-bit operating system; a 32-bit OS will limit recognised memory to 3.5GB or less.

Will these DDR3L 1600 modules down-clock if the notebook only supports DDR3-1333?

The kit is rated for DDR3L 1600 (PC3L 12800) and will automatically run at the lower 1333 MHz speed supported by the platform.

How can I confirm the memory is running in dual-channel mode after installation?

Install the two 4GB sticks as a matched pair in the two sockets; the system BIOS or a tool like CPU-Z will then report dual-channel operation.
