ECC Registered DDR4 for QNAP NAS

This 16 GB DDR4 2666 module is built as a registered ECC RDIMM for server and NAS platforms. It carries a CL19 latency and runs at 1.20 V, using major-brand DRAM chips. The 288-pin form factor matches standard DDR4 server slots.

Suited for QNAP upgrades.

The stick targets administrators upgrading compatible QNAP NAS units that require registered ECC memory. Builders using consumer motherboards that accept only unbuffered non-ECC DIMMs cannot use this module. Workstations needing registered ECC DDR4 may use it if the platform qualifies.

Registered ECC RDIMM decides fit

The single specification that determines compatibility is the registered ECC RDIMM design. Systems that require unbuffered UDIMMs or non-ECC memory will not accept this part. Verify the platform documentation before purchase.

Questions about this item

Does the 16GB DDR4 2666 module arrive as a single stick or do I need to order a kit?

The module is supplied as one 16GB stick; no extra parts are included.

Why choose the 2Rx8 registered ECC version over a non-ECC alternative?

The 2Rx8 registered ECC design provides error correction and signal buffering required by compatible QNAP NAS and server platforms.

What does the PC4-21300 rating tell me about real-world throughput?

PC4-21300 denotes the module's peak data rate at 2666 MT/s with CL19 latency and 1.2V operation.
