NEMIX RAM 8GB DDR4 2666 PC4-21300 CL19 1Rx8 ECC RDIMM server RAM

8GB DDR4 ECC RDIMM for NAS

This 8GB DDR4 2666 module is built for QNAP NAS devices and other servers that require registered ECC memory. It uses a 288-pin RDIMM form factor with a 1Rx8 organisation. The stick runs at 1.2V and carries a CL19 latency rating. It targets administrators who need validated, error-correcting capacity for storage appliances or entry-level servers.

Sustained load behaviour

The module is stress-tested under load to verify stability during continuous operation. Registered buffering and ECC functionality maintain data integrity across extended workloads such as file serving, backup jobs or virtualisation tasks. Major OEM DRAM chips from Samsung, Micron or Hynix provide consistent signalling at the rated 2666 MT/s speed. The 1Rx8 rank layout helps keep the command bus predictable during long transfers.

Thermals noise and power

Operating at 1.20V keeps power draw low for a registered DIMM. No heat spreader is fitted, so airflow across the bare PCB is the only cooling requirement. In a typical NAS chassis with directed airflow the module runs silently and stays within normal DDR4 temperature limits. The low voltage and single-rank design minimise heat contribution to the system's overall thermal budget.
