16 GB DDR4 ECC RDIMM for QNAP NAS

This registered DIMM delivers 16 GB of DDR4 memory with ECC protection for compatible QNAP NAS devices. It targets IT professionals and system builders who need validated server-grade modules for mission-critical storage appliances. The single-module design simplifies capacity planning in multi-bay enclosures.

Registered 2Rx8 organisation at DDR4-2400 CL17

The module operates at DDR4-2400 (PC4-19200) with CAS latency 17 and 1.20 V. Its 2Rx8 rank configuration and registered buffer ensure signal integrity on populated memory channels. This specification determines whether the part matches the motherboard's qualified-vendor list.

Sustained load stability through stress-tested OEM

Each stick uses major OEM Samsung, Micron or Hynix components that undergo rigorous stress testing under load before shipment. The registered architecture and ECC correction maintain data integrity during continuous NAS workloads such as RAID rebuilds, virtualization hosting or backup streaming. No heat spreader is fitted, relying on chassis airflow for thermal management.

Questions about this item

What does the DDR4-2400 speed mean once the module is installed in a server?

The module runs at 2400 MT/s, delivering up to PC4-19200 bandwidth when the platform supports that data rate.

How does the registered ECC interface affect what the memory can do in practice?

Registered ECC adds a register between the DRAM and the memory controller, enabling error correction and allowing higher-capacity configurations on compatible server boards.

What physical slot and pin count does this 16 GB stick need to fit?

It requires a 288-pin DDR4 RDIMM slot, the standard form factor for registered server memory modules.
