SAMSUNG M471A2K43CB1-CTD 16GB DDR4 2666MHz CL19 1.2V laptop RAM

Capacity and fit

This is a 16GB DDR4 SO-DIMM built for laptops that accept 260-pin modules. It runs at 2666MHz with CL19 latency and a standard 1.20V supply. The unbuffered, non-ECC design suits mainstream notebooks and compact workstations. Buyers needing registered or error-correcting memory should look elsewhere.

Sustained workload behaviour

The module operates at the JEDEC-standard 2666MHz data rate under continuous load without requiring a voltage increase beyond 1.20V. CL19 timing provides predictable latency for multitasking and background services. Stability is validated through extended stress testing rather than brief benchmarks. Systems limited to lower memory speeds will clock the module down automatically.

Build and daily implications

Samsung DRAM components are assembled on a standard green PCB with gold edge contacts for reliable slot insertion. The low-profile height fits thin-and-light chassis where taller modules would conflict with the keyboard deck or cooling assembly. Dual-rank 2Rx8 organisation helps populate two-channel controllers efficiently. No heatsink or lighting is included, keeping weight minimal for portable devices.
