16GB DDR4 3200 ECC DIMM

This 16GB DDR4 3200 CL22 ECC unbuffered DIMM is built for workstations, servers and NAS systems that require error-correcting memory. It runs at 1.2V and follows JEDEC PC4-25600 specifications for reliable operation in compatible desktop platforms.

Installation and common issues

The 288-pin module installs in a standard DDR4 DIMM slot and is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz buses. Systems that do not support ECC or that require registered memory will not recognise the module correctly.

Suitable buyers and alternatives

This suits administrators upgrading QNAP NAS units or adding ECC capacity to supported workstations and servers. Builders needing non-ECC memory, registered DIMMs or higher speeds should select a different module.

商品問答

How do I verify the OWC 16GB DDR4 3200 CL22 module is running at its rated speed after installation?

Check the memory tab in CPU-Z or your BIOS/UEFI; it should report DDR4-3200 with CL22 timings at 1.2V. If the system defaults to 2133, 2400, 2666 or 2933 MHz, enable the XMP or DOCP profile to reach 3200 MHz.

What comes in the box with the OWC 16GB DDR4 3200 ECC unbuffered DIMM and what must I source separately?

The package contains the single 288-pin 16GB DDR4 ECC unbuffered DIMM. You must provide a compatible desktop, workstation, server or NAS motherboard with a free DDR4 slot; no cables, screws or additional parts are included.

Which OWC DDR4 ECC unbuffered DIMM capacity should I choose for a QNAP NAS that takes the RAM-16GDR4ECK1-UD-3200 part?

Select the 16GB module (part 3E2D41R816GB) — it matches the QNAP specification exactly. If your NAS has multiple slots you can add identical 16GB sticks to reach the platform’s maximum supported capacity.
