32GB DDR4 2666MHz SODIMM

This OWC module delivers a single 32GB DDR4 stick rated at 2666MHz with CL19 latency. It uses the 260-pin SO-DIMM form factor and runs at the standard 1.2V. The memory is unbuffered, non-ECC and built to JEDEC specifications for broad compatibility.

Suits laptops, all-in-ones

Buyers whose systems only accept smaller individual modules or require registered ECC memory should look elsewhere. The 2RX8 organisation works with most consumer platforms, but platforms limited to lower maximum densities will not recognise the full capacity. Systems without a free SO-DIMM slot cannot use this module.

32GB single-module capacity

The decisive specification is the 32GB density on one SO-DIMM. It lets you reach that total in a single slot, which is essential when only one slot is available or when the platform caps at 32GB per slot. Verify your device supports 32GB modules before purchase.

Questions about this item

My laptop only has DDR4 slots — will this 260-pin SODIMM fit?

Yes. This module uses the 260-pin DDR4 SO-DIMM form factor, so it fits any laptop slot built for DDR4 memory.

I still have a 2400MHz stick in the other slot — will they work together?

The module is backwards compatible with 2400MHz and 2133MHz speeds, so it will run at the lower frequency alongside your existing stick.

After installing the 32GB module, how can I confirm it is running at 2666MHz CL19?

Open Task Manager or a system-information tool and check the memory speed and CAS latency reported for the new module.
