16GB DDR4 ECC SODIMM for laptops and NAS

This OWC module adds 16GB of DDR4 2133MHz memory with ECC error correction. It fits 260-pin SO-DIMM slots in laptops, all-in-one PCs and compatible NAS units. The unbuffered design operates at 1.2V with CL15 latency.

Replaces non-ECC or lower-capacity DDR4 SODIMMs

Swapping a standard module for this ECC version adds data-integrity protection for workloads that cannot tolerate silent corruption. The upgrade is worthwhile when your system supports ECC and you need 16GB in a single slot.

Suits ECC-capable laptops, AIOs and micro servers

Buyers whose platforms lack ECC support or require registered DIMMs should look elsewhere. Systems limited to speeds below 2133MHz will still run the module at the lower rate. Those needing more than 16GB per slot must choose higher-density kits.

Questions about this item

Does the 260-pin SO-DIMM fit standard laptop DDR4 slots?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the standard slot used in laptops, all-in-one PCs and compatible NAS units.

What is the correct way to seat the module so the ECC function works?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click — partial seating is the common error that prevents ECC operation.

Will the 1.2 V DDR4 chips need active cooling or replacement over time?

No heat spreader is fitted and the JEDEC 1.2 V design runs within normal thermal limits, so no extra cooling or scheduled replacement is required.
