Questions about this item

How can I confirm the 16GB DDR4 3200MHz module is running at CL22 1.2V after installing it in my Dell Inspiron 14 5401?

Open Task Manager's Performance tab or run CPU-Z; the memory section will show 16GB capacity, 3200MHz speed, CL22 timings and 1.2V voltage when the SODIMM is seated correctly.

What ships with the OWC 3S2D42R816GB SODIMM and do I need any extra parts for my Dell Inspiron 14 5406?

The box contains only the 260-pin DDR4 SODIMM; no tools, screws or additional cables are required for installation in the Inspiron 14 5406.

Which capacity should I choose between the 16GB stick and a 32GB kit for my Dell Inspiron 14 5409?

The listed part is a single 16GB module; if your 5409 has one free slot this adds 16GB, while a 32GB kit would require two slots and is a different product.
