OWC 16GB DDR4 ECC Registered RDIMM

This 16GB DDR4 2666 ECC Registered RDIMM is built for the QNAP TS-2888X NAS system. It delivers 16GB capacity at PC4-21300 speed with CL19 latency and 1.2V operation. The module uses a 2Rx8 rank configuration on a 288-pin form factor. It is not compatible with standard desktop computers or unbuffered memory.

Installing in the QNAP TS-2888X

Installation follows the standard DIMM slot procedure for the TS-2888X chassis. The registered design requires a compatible server or workstation platform; it will not function in consumer motherboards. A common error is attempting to mix this registered module with unbuffered memory, which prevents boot. Ensure all slots use matching ECC registered specifications.

Verify your NAS model and memory configuration

Confirm the unit is a QNAP TS-2888X before ordering, as this module is system-specific. Check existing installed memory to avoid mixing registered and unbuffered types. The module is backward compatible with 2133MHz and 2400MHz operation. Buyers needing non-ECC memory or desktop DIMMs should select a different product.

Questions sur cet article

How do I verify the 16GB DDR4 2666 module is recognised and running at CL19 after installing it in my QNAP TS-2888X?

After installation, open the QNAP TS-2888X web interface, go to System Information or Hardware Monitor, and confirm the total capacity shows the added 16GB and the memory speed reads 2666MHz with CL19 timing.

What comes in the box and do I need any extra brackets or cables for the 288-pin RDIMM?

The box contains one OWC 16GB DDR4 2666 PC4-21300 CL19 2Rx8 288-pin 1.2V ECC Registered RDIMM module; no brackets, cables or additional parts are required for installation in the QNAP TS-2888X.

Should I choose the 16GB 2Rx8 CL19 version or a different capacity for my TS-2888X?

This single 16GB 2Rx8 CL19 RDIMM matches the QNAP part numbers RAM-16GDR4ECK0-RD-2666 and RAM-16GDR4ECT0-RD-2666; select it when you need one 16GB registered ECC module for the TS-2888X.
