16 GB DDR4 laptop upgrade

This 260-pin SODIMM adds 16 GB of DDR4 memory to a compatible notebook. It runs at 2400 MHz with CL17 timings and is built for unbuffered, non-ECC operation. The single-module design suits users who need a straightforward capacity increase without populating multiple slots.

Low-voltage thermal profile

Operating at 1.2 V the module draws minimal power and generates little heat inside a compact chassis. Passive cooling from the laptop's existing airflow is sufficient; no additional fans or heatsinks are required. The low voltage also helps preserve battery life during everyday workloads.

Fits standard DDR4 SODIMM slot

The stick plugs directly into any 260-pin DDR4 SO-DIMM socket that accepts 1.2 V unbuffered modules. It leaves other slots free for future expansion and does not demand BIOS changes beyond standard JEDEC detection. Buyers who need ECC error correction or registered buffering should look elsewhere.

Questions about this item

How do I install the 260-pin DDR4 SODIMM in my laptop?

Power off and unplug the laptop, open the memory compartment, align the notch on the module with the slot key, insert at an angle, then press down firmly until both side clips click — the step people miss is fully seating both clips.

What maintenance or replacement will the 16GB DDR4-2400 module need later?

No scheduled maintenance is required; keep the contacts clean and ensure the laptop's cooling vents stay clear so the module operates within its 1.2V specification.

What limit appears first when the CT16G4SFD824A runs sustained workloads at 2400MHz?

The CL17 latency at 1.2V is the primary constraint; sustained throughput is capped by the DDR4-2400 bus speed and fixed timing of 17-17-17.
