16 GB DDR4 ECC UDIMM for QNAP NAS

This 16 GB DDR4 2666 CL19 ECC UDIMM module adds error-correcting memory to compatible QNAP NAS devices. It runs at 1.2 V on a 288-pin unbuffered DIMM with a 2Rx8 organisation. The kit contains a single stick built with major OEM DRAM chips.

Suits QNAP NAS upgrades needing ECC.

The module targets IT professionals upgrading QNAP NAS units that require DDR4 ECC unbuffered memory. Systems that only accept non-ECC UDIMMs or registered DIMMs cannot use this part. Buyers without a compatible QNAP model should look at something else.

Single 16 GB DDR4 2666 CL19 ECC UDIMM at 1.2 V

The decisive specification is the 16 GB capacity combined with DDR4 2666 speed, CL19 latency, ECC support and unbuffered 288-pin form factor. Match these exact parameters to your NAS motherboard manual before ordering.
