System-Specific DDR4 SODIMM for Dell Latitude

This 16GB DDR4 module is built for Dell Latitude 5521 and 5530 laptops. It installs in a standard 260-pin SO-DIMM slot and runs at 1.2V without ECC. The upgrade targets owners of those models who need more memory for everyday workloads.

Speed and latency matched to OEM spec

The stick operates at 3200MHz (PC4-25600) with a CAS latency of CL22. These figures match the factory memory specification, so the module will run at its rated speed without manual tuning. Builders using other Dell models or non-DDR4 platforms cannot use this part.

Low-voltage operation keeps thermals in check

At 1.2V the module draws minimal power and produces little heat, so laptop fans do not spin faster under normal loads. The unbuffered, non-ECC design adds no active cooling requirement. Systems already limited by chassis airflow will not see a thermal penalty.

Questions about this item

What does the 3200MHz speed actually deliver in a Latitude 5521 or 5530?

The module runs at DDR4 3200 with CL22 latency, giving the rated PC4-25600 bandwidth when the system memory controller is set to that speed.

Does the PC4-25600 rating limit what the stick can do in these laptops?

PC4-25600 is the JEDEC standard name for DDR4 3200; the Latitude 5521 and 5530 memory controllers support this speed, so the rated bandwidth is available.

Will the 260-pin SODIMM fit the memory slot in a Latitude 5521 or 5530?

Yes — both models use standard 260-pin DDR4 SODIMM slots, and this unbuffered non-ECC module matches the required form factor exactly.
