Single 16 GB DDR4 SODIMM

This OWC module delivers 16 GB of DDR4 memory in a 260-pin SO-DIMM format. It runs at 2400 MHz with CL17 latency and operates at 1.2 V. The stick is unbuffered, non-ECC and has no heat spreader. It is intended for laptops, all-in-one systems and NAS devices.

Suitable for DDR4 2400 MHz slots

Builders upgrading a laptop, mini desktop, micro server or POS terminal that accepts DDR4 2400 MHz SO-DIMMs will find this module a direct fit. It is also backwards compatible with 2133 MHz slots. Systems that require ECC, registered memory or a different pin count cannot use this module.

260-pin DDR4 2400 MHz form factor

The deciding specification is the 260-pin DDR4 SO-DIMM running at 2400 MHz (PC4-19200). Verify that the target device supports this exact form factor and speed before purchase.

Questions about this item

Will this 260-pin DDR4 2400 CL17 module run alongside my existing 2133 MHz SODIMMs?

Yes — the module is backwards compatible with 2133 MHz systems and will operate at the lower speed when mixed with slower memory.

How can I confirm the 16 GB stick is recognised at 2400 MT/s with CL17 timings after installation?

Check the memory tab in CPU-Z or the BIOS/UEFI main screen; it should show 16 GB, DDR4-2400, and CAS latency 17.

Does the 2S4D42R816GB box contain only the single 16 GB SODIMM or any extra accessories?

The package includes only the 16 GB 260-pin DDR4 SODIMM; no tools, screws or additional cables are supplied.
