OWC 8GB DDR4 2666MHz CL19 1.2V SODIMM laptop RAM

Single-module 8 GB upgrade

This OWC DDR4 SODIMM adds 8 GB of memory to laptops, all-in-one desktops, mini PCs, micro servers and NAS units that accept 260-pin unbuffered non-ECC modules. It is built for owners who need a straightforward capacity increase without changing voltage or form factor.

2666 MHz JEDEC speed rating

The module runs at DDR4 2666 (PC4-21300) with a CAS latency of 19 at 1.2 V, matching the JEDEC standard that most current laptop platforms expect. Systems that specify a lower speed will simply clock the memory down to 2400 MHz or 2133 MHz without further adjustment.

8 GB capacity for everyday multitasking

Eight gigabytes handles web browsing, office suites, light photo editing and typical NAS workloads comfortably. Workloads that keep many large applications or virtual machines open simultaneously will exceed this single module and require additional slots or higher-density sticks.
