SKU CH-SQYZ-BCNCQ GTIN 885022018796

ECC DDR4 memory module adds 16 GB at 2666 MHz for compatible QNAP systems

  • 16 GB ECC DDR4 protects data integrity
  • 2666 MHz DDR4 speed supports responsive surveillance workloads
  • UDIMM form factor fits compatible QNAP NAS bays
  • T0 version ensures validated compatibility with supported systems

16 GB ECC DDR4 module

This 16 GB ECC DDR4 module runs at 2666 MHz in a UDIMM form factor for compatible QNAP systems. It adds error-correcting memory to protect data integrity in always-on surveillance and storage workloads. The T0 revision matches the vendor qualification list for supported appliances. Builders who need non-ECC memory or a different speed grade should select another module.

Sustained-load behaviour

Error-correcting code detects and corrects single-bit errors during continuous read-write cycles typical of recording and indexing video streams. The registered timing holds stable at the rated frequency without thermal throttling in ventilated chassis. Systems that require higher density per slot or lower voltage operation will not be served by this part.

Questions about this item

How much heat does a 16GB DDR4 ECC UDIMM running at 2666 MHz generate during continuous operation?

ECC DDR4 UDIMM modules run at standard JEDEC voltage and produce modest warmth; typical NAS chassis airflow is sufficient to keep temperatures within normal limits.

What motherboard slot and memory controller are required to use this 16GB DDR4 ECC UDIMM?

The module needs a standard DDR4 UDIMM slot and a CPU or chipset that supports ECC unbuffered memory at 2666 MHz.
