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

SKU CH-BY6Q-00VEW

An 8 GB DDR4 SODIMM running at 2666 MHz with CL19 latency and 1.2 V operation for laptops and NAS systems

  • Total capacity8 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latency19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Recommended forLaptops, All-in-One Systems, and NAS Systems
  • Boost responsiveness with 8GB DDR4 2666MHz CL19
  • Low 1.2V voltage reduces laptop power draw
  • JEDEC and RoHS compliant for warranty-safe upgrade
  • Backward compatible with 2400MHz and 2133MHz systems
  • 260-pin SODIMM fits laptops, AIOs and NAS devices

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.

Questions about this item

What does the 2666MHz speed actually deliver once the module is installed?

The module runs at 2666MHz CL19 at 1.2V, giving a PC4-21300 data rate that the system will use automatically if the platform supports that speed.

How does the DDR4 260-pin SODIMM interface limit performance in practice?

The 260-pin DDR4 SODIMM slot caps the module at the JEDEC 2666MHz standard; it will down-clock to 2400MHz or 2133MHz on older platforms.

What physical space and slot does this 8GB stick need to fit?

It requires a single 260-pin DDR4 SODIMM slot and has no heat spreader, so it fits standard laptop, mini-desktop, micro-server and NAS sockets.
