OWC 8GB DDR4 2666MHz CL19 ECC SODIMM 1Rx8 1.2V memory upgrade

SKU CH-4KTJ-DC1FB

An 8 GB DDR4 2666 MHz ECC SODIMM validated for Synology DiskStation DS2419+ and DS2419+II NAS systems

  • Capacity8GB
  • Type260-Pin DDR4 ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes

Capacity 8GB

  • 8GB capacity expands NAS multitasking headroom
  • DDR4 2666MHz CL19 speed matches system spec
  • ECC protection guards data integrity in storage
  • 2V low voltage reduces power draw
  • Validated for Synology DS2419+ and DS2419+II

What this memory upgrade is

This is an 8GB DDR4 2666MHz CL19 ECC SODIMM module designed for Synology DiskStation DS2419+ and DS2419+II NAS systems. It operates at 1.2V with a 1Rx8 unbuffered configuration. The 260-pin form factor fits compatible micro servers and POS hardware. JEDEC and ROHS compliance ensures a warranty-safe upgrade.

Who this suits and who should look elsewhere

This module suits administrators expanding memory in the listed Synology NAS models or similar micro servers requiring ECC SODIMM memory. It supports backward compatibility with 2400MHz and 2133MHz systems. Buyers needing non-ECC memory, DIMM form factors, higher capacities per module, or faster speeds than 2666MHz should look at other options.

How it fits into a build

The SODIMM installs directly into an available memory slot on the compatible NAS motherboard. No heat spreader is included, so airflow around the module depends on the system chassis. Adding this memory frees up capacity for larger datasets, more concurrent users, or additional virtual machines. Ensure the NAS firmware supports the total installed memory configuration.

Questions sur cet article

Which Synology DiskStation models must I already own for this 260-pin DDR4 SODIMM to be compatible?

The module is validated for the Synology DiskStation DS2419+ and DS2419+II NAS systems.

How will this CL19 2666MHz ECC module behave if I keep existing 2400MHz memory in the same NAS?

It is backward compatible with 2400MHz and 2133MHz speeds, so the system will run all modules at the lowest common frequency.

How can I verify the 8GB ECC SODIMM is running at PC4-21300 2666MHz with CL19 timings after installation?

Check the Synology DSM memory information page; it will report the installed capacity, speed and ECC status for each slot.
