OWC 16GB DDR4 2666 ECC SODIMM

This OWC 16GB DDR4 2666 ECC SODIMM module is designed for Synology ActiveProtect DP320 and DP340 systems. It adds error-correcting memory capacity to compatible micro servers and NAS devices. The module is not suitable for standard consumer laptops or desktops that require non-ECC memory.

Installation is a straightforward DIY task

The 260-pin SODIMM slots into the memory socket on the target Synology unit. Because the module is unbuffered ECC, the system must support ECC functionality; otherwise the module will not operate correctly. No heat spreader is present, so ensure adequate airflow inside the chassis.

DDR4 2666 with backward compatibility

The module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V. It is backward compatible with 2400MHz and 2133MHz DDR4 systems, automatically downclocking when installed in slower platforms. Maximum throughput is limited by the DDR4 2666 interface and the host system's memory controller.

商品問答

How can I verify the 16GB DDR4 2666 ECC SODIMM is running correctly after installing it in my Synology ActiveProtect DP320?

After installation, power on the Synology ActiveProtect DP320 and check the system information or DSM resource monitor; it should report the full 16GB capacity at 2666MHz with ECC active.

What comes in the box with the OWC 2C6D42R816GB module and do I need any extra parts for the DP340?

The package contains a single 16GB 260-pin DDR4 2666 CL19 2Rx8 1.2V ECC unbuffered SODIMM; no additional cables, brackets or tools are required for the DP340.

Which capacity should I choose between the 16GB 2C6D42R816GB and other OWC DDR4 2666 ECC SODIMM options for my ActiveProtect unit?

Select the 16GB 2C6D42R816GB when you need a single-module upgrade to reach 16GB total; choose a different capacity only if your target total memory differs.
