16GB DDR5 ECC SODIMM for Laptops and NAS

This module provides 16GB of DDR5 memory at 4800MT/s with CL40 latency and ECC error correction. It uses a 262-pin SO-DIMM form factor and operates at 1.1V. The unbuffered design suits laptops, all-in-one PCs and NAS appliances.

Suits ECC-capable mobile systems.

Buyers whose laptops or NAS units support DDR5 ECC SO-DIMMs can install this module for data-integrity protection. Systems that require non-ECC memory or lack DDR5 SO-DIMM slots cannot use this part.

ECC on DDR5 SO-DIMM decides compatibility

The single specification that determines fit is ECC support on a DDR5 262-pin SO-DIMM slot. If the platform accepts unbuffered ECC modules at 4800MT/s, this upgrade works; otherwise it will not function.

Questions about this item

Does my laptop need a DDR5-compatible 262-pin SO-DIMM slot to use this module?

Yes, this is a DDR5 262-pin SO-DIMM and requires a laptop or all-in-one with a DDR5 SO-DIMM slot.

Will this ECC unbuffered DDR5 4800 CL40 module run in a system that currently uses non-ECC DDR5 memory?

It will only operate if the platform supports ECC unbuffered memory; most consumer laptops do not enable ECC.

How can I verify the module is running at DDR5 4800 CL40 after installation?

Check the memory speed and timings in BIOS or a system-information tool such as CPU-Z to confirm 4800 MT/s and CL40.
