Samsung laptop upgrade

This 8 GB DDR4 SODIMM is built for Samsung laptops and all-in-one PCs that need a straightforward memory increase. It fits systems requiring 260-pin unbuffered non-ECC modules at 1.2 V. The single-rank 1Rx8 layout matches the original Samsung M471A1K43DB1-CTD specification for direct compatibility.

CL19 headroom at 2666 MT/s

Running at 2666 MT/s with PC4-21300 bandwidth and CL19 latency, the module handles everyday multitasking, office suites and light content workloads without bottlenecking the integrated memory controller. Heavy virtualisation, large dataset processing or memory-bound rendering will exhaust the 8 GB capacity before the speed ceiling becomes the limiting factor.

Drop-in 260-pin form factor

The stick installs in any standard DDR4 SODIMM slot without a heat spreader, keeping the profile low for thin chassis. No BIOS voltage tuning is required because the JEDEC 1.2 V default is already programmed. It frees the single remaining slot for a future second module if the platform supports dual-channel operation.

Questions about this item

Will this DDR4 2666 CL19 1.2 V SODIMM run alongside the original Samsung memory already in my laptop?

It matches Samsung DDR4 2666 PC4-21300 1.20 V CL19 1Rx8 spec, so the system will clock both modules to the same speed and timings.

How can I confirm the module is running at 2666 MHz and CL19 after installation?

Open Task Manager Performance tab or CPU-Z; both will show 2666 MHz and CAS 19 when the stick is seated correctly.

Does the package include only the 8 GB 260-pin SODIMM or are tools and adapters supplied?

The box contains the single 8 GB 260-pin DDR4 SODIMM; no screwdriver, bracket or adapter is included.
