8GB DDR4 SODIMM for Samsung laptops

This 8 GB DDR4 module runs at 2666 MHz with CL19 latency and 1.20 V operation. It uses a 260-pin SODIMM form factor and 1Rx8 unbuffered, non-ECC chips. The stick is validated for Samsung M471A1K43CB1-CTD compatibility.

DDR4 2666 speed ceiling on SODIMM

DDR4 2666 (PC4-21300) is the rated transfer rate; the laptop memory controller will not exceed this frequency. CL19 timing and 1Rx8 organisation are fixed by the SPD profile. No heat spreader is fitted, so airflow in tight chassis matters.

Verify slot count and maximum capacity

Confirm the target Samsung laptop or AIO accepts 260-pin DDR4 SODIMMs and supports 8 GB per slot. Check the service manual for total memory limit and whether 1Rx8 modules are listed. Ensure the system does not require ECC or registered memory.

Questions about this item

Should I pick the 1Rx8 8 GB module or look for a dual-rank alternative?

This module is single-rank 1Rx8 at CL19, which keeps electrical load low and works well in most two-slot laptops; a dual-rank stick would draw more power and is not offered here.

What does the PC4-21300 rating actually deliver in a laptop?

PC4-21300 equals 2666 MT/s peak bandwidth, so the stick runs at 2666 MHz with CL19 timing at the standard 1.20 V.

Will the 260-pin SODIMM fit every DDR4 laptop slot?

The 260-pin DDR4 SODIMM form factor is the industry standard for laptop memory, so it fits any notebook that accepts DDR4 SO-DIMMs.
