32GB DDR4 2666MHz laptop module

This is a single 32GB DDR4 SO-DIMM running at 2666MHz with CL19 latency and 1.20V operation. The 260-pin unbuffered non-ECC stick is built as a direct replacement for the Samsung M471A4G43MB1-CTD part number.

Suits notebooks needing one 32GB stick

Buyers whose laptop has a single SO-DIMM slot and supports DDR4 2666MHz will gain the full 32GB capacity in one module. Systems limited to lower maximum memory per slot or requiring ECC registered memory should look at something else.

Simple press-in installation

Align the notch on the 260-pin edge connector with the slot key, insert at a slight angle, then press down until the side clips lock. The most common issue is the module not seating fully, which causes the laptop to fail POST or show no memory detected.

Perguntas sobre este artigo

My laptop only has one SO-DIMM slot — will this single 32GB module work on its own?

Yes, this is a single 32GB DDR4 2666MHz CL19 module that runs at 1.20V and fits a standard 260-pin slot, so it operates independently without needing a second stick.

I plan to keep my existing DDR4 2666MHz stick in the second slot — will both modules run together at 2666MHz?

If the existing stick is also DDR4 2666MHz CL19 at 1.20V unbuffered non-ECC, the system will run both at 2666MHz; mixing different speeds or latencies forces the faster module down to the slower one.

After installing the module, how can I confirm it is running at 2666MHz with CL19 timings?

Open Task Manager → Performance → Memory or run CPU-Z; the speed should show 2666MHz (PC4-21300) and the CAS latency should read 19 when the system is under load.
