128GB DDR4 ECC SODIMM Kit

This OWC kit provides 128GB of DDR4 3200MHz ECC memory across four 32GB modules. It is built for laptops, all-in-one systems and NAS devices that support 260-pin SO-DIMM slots and can use unbuffered ECC memory. The CL22 latency and 1.2V operation follow JEDEC standards for broad compatibility.

Check Slot Count and ECC Support

Verify that your system has four available 260-pin SO-DIMM slots and that its memory controller accepts unbuffered ECC modules. Many consumer laptops only offer two slots or disable ECC functionality, so this kit will not work in those machines. The modules are backward compatible with 2933MHz, 2666MHz, 2400MHz and 2133MHz speeds if the platform requires a lower rate.

Fits Four-Slot ECC Platforms

Populating all four slots delivers the full 128GB capacity in a dual-channel configuration where the platform supports it. The low-profile design without a heat spreader helps the modules fit tight spaces inside compact laptops or NAS enclosures. Using ECC memory adds data-integrity protection for workloads such as file servers or virtualization hosts that benefit from error correction.

Questions about this item

Does the 128GB kit contain four 32GB SODIMMs or do I need to buy extra sticks?

The kit includes four 32GB modules for a total of 128GB, so no additional sticks are required.

Should I choose this 128GB CL22 kit or a lower-capacity alternative for my NAS?

Choose this 128GB CL22 ECC kit when your NAS or micro server supports 260-pin DDR4 and you need maximum capacity with error correction.

Will the advertised 3200MHz speed actually run at 3200MHz in my laptop?

The modules run at 3200MHz when the system supports it; otherwise they automatically operate at 2933MHz, 2666MHz, 2400MHz or 2133MHz.
