Compatible Samsung Laptop Memory

This 16 GB DDR4 SODIMM is built for Samsung laptops and all-in-one PCs that accept PC4-21300 unbuffered modules. It uses major OEM chips from Samsung, Micron or Hynix and runs at the standard 1.20 V. The single-rank 2Rx8 organisation fits the factory slot without modification.

Sustained Workload Behaviour

Modules are stress tested under load before shipping to verify stability during extended sessions. The CL19 latency and 2666 MT/s data rate remain consistent when the system runs memory-intensive tasks for long periods. Non-ECC unbuffered operation keeps the signal path direct for predictable throughput.

Pre-Installation Checks

Confirm the device uses 260-pin DDR4 SODIMM slots and supports 16 GB per slot at 2666 MHz. Verify the BIOS recognises PC4-21300 CL19 timings at 1.20 V without manual adjustment. Ensure the chassis provides access to the memory compartment for a tool-free swap.

Questions about this item

How much power does this 1.2 V DDR4 SODIMM draw under continuous load?

It operates at the standard DDR4 voltage of 1.20 V; actual power draw depends on the laptop's memory controller and workload, not on the module alone.

What must my Samsung laptop already have to accept this 260-pin CL19 module?

A free DDR4 SODIMM slot that supports 2666 MHz PC4-21300 unbuffered non-ECC memory and a BIOS that recognises 16 GB 2Rx8 density.

Will this 2Rx8 16 GB stick run at its rated 2666 MHz if I keep an older 8 GB DDR4 module in the second slot?

Both modules will run at the lowest common speed supported by the platform; if the older stick is slower, this one will downclock to match.
