8GB DDR4 2666 SODIMM for Samsung systems

This module delivers 8 GB of DDR4 memory at 2666 MHz with CL19 latency. It is built for Samsung laptops and all-in-one PCs that accept 260-pin SODIMMs. The single-rank 1Rx8 design runs at 1.2 V without ECC or buffering.

Check your Samsung device before ordering

Verify the machine uses DDR4 SODIMM slots and supports 2666 MHz PC4-21300 speeds. Confirm the motherboard accepts non-ECC unbuffered modules and has a free 260-pin slot. Match the CL19 timing and 1.2 V voltage to the existing configuration.

Fits a single-slot upgrade in compatible Samsung

The stick occupies one 260-pin socket and requires no heat spreader clearance. It leaves remaining slots open for further expansion if the chassis allows. No extra power connectors or BIOS changes are needed beyond standard DDR4 support.
