Single-module 32 GB DDR4 upgrade

This OWC SODIMM delivers 32 GB of DDR4 memory in one 260-pin module rated at 2666 MHz with CL19 latency. It is built for laptops, all-in-one desktops and NAS units that accept non-ECC unbuffered memory at 1.2 V. The single-stick design leaves other slots free for future expansion.

Check slot count and maximum capacity

Verify that your system uses 260-pin DDR4 SODIMM slots and supports a 32 GB module in a single bank. The board must run at 1.2 V and accept non-ECC unbuffered memory. Confirm the firmware allows 2666 MHz operation or will down-clock to 2400 MHz or 2133 MHz as needed.

JEDEC-standard build with no heat spreader

The module follows JEDEC and RoHS specifications and carries no heat spreader, keeping the profile low for tight chassis. Gold-edge contacts on the 260-pin connector ensure reliable seating in standard SODIMM sockets. The bare-PCB design simplifies installation in cramped laptop bays or dense NAS enclosures.

Questions about this item

Does the module arrive alone or with any extra hardware such as a heat spreader or screwdriver?

The module ships as a single 32GB DDR4 2666MHz CL19 SODIMM with no heat spreader and no installation tools included.

Why choose this 32GB CL19 stick instead of a lower-capacity or lower-latency alternative?

This part number provides 32GB in one 2Rx8 260-pin slot at JEDEC-standard 2666MHz CL19, maximising capacity per slot for laptops, all-in-ones or NAS units that accept DDR4 SODIMMs.

Will the rated 2666MHz speed actually run at that frequency once installed?

The module is rated PC4-21300 2666MHz CL19 at 1.2V and is backward compatible with 2400MHz and 2133MHz systems, so it will operate at the highest speed the platform supports.
