OWC 16GB DDR4 2666MHz CL19 260-pin SODIMM laptop RAM

SKU CH-JEBN-1HNMA

Adds 16 GB of DDR4 2666 MHz CL19 memory to compatible laptops, all-in-ones and NAS systems with 260-pin slots

  • Capacity16GB
  • Type260-Pin DDR4 Non-ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS Latency19
  • Voltage1.2V
  • ECCNo
  • 16 GB single module boosts multitasking capacity
  • 2666 MHz DDR4 speed matches PC4-21300 standard
  • CL19 latency at 1.2 V keeps power draw low
  • 260-pin SODIMM fits laptops, all-in-ones and NAS units
  • Backward compatible with 2400 MHz and 2133 MHz systems

Single 16GB DDR4 SODIMM

This 260-pin DDR4 module delivers 16GB at 2666MHz with CL19 latency and 1.2V operation. It is built for laptops, all-in-one PCs, mini desktops, micro servers and NAS appliances that accept unbuffered non-ECC SODIMMs. The JEDEC-standard design keeps the upgrade warranty-safe.

Upgrade from 2133MHz or 2400MHz DDR4

Backward compatibility lets this stick run in slots rated for 2133MHz or 2400MHz DDR4, so owners of older DDR4 platforms can add capacity without replacing the whole kit. The jump is worth it when the system supports 2666MHz and the workload needs the extra bandwidth.

16GB capacity for multitasking headroom

A single 16GB module handles large spreadsheets, multiple browser tabs and light virtual machines comfortably. It runs out when the platform requires ECC or registered memory, when the slot count limits total capacity below the workload, or when the application demands speeds above 2666MHz.

Questions about this item

Will the 260-pin DDR4 SODIMM fit my laptop's memory slot?

This module uses the standard 260-pin DDR4 SODIMM form factor and 1.2V voltage required by compatible laptop slots.

What is the correct way to seat the module so it locks in place?

Align the notch with the slot key, insert at a 30-degree angle, then press down firmly until both side clips click audibly.

Will this RAM need any firmware updates or wear out over time?

No firmware is required; the JEDEC-compliant DDR4 chips have no moving parts and are rated for the system's lifetime.
