OWC 64GB (2x32GB) DDR4 2666 CL19 ECC UDIMM 2Rx8 1.2V ASUSTOR AS7112RDX AS7116RDX

64 GB DDR4 ECC kit for ASUSTOR NAS

This 64 GB kit contains two 32 GB DDR4 2666 CL19 ECC UDIMMs validated for ASUSTOR AS7112RDX and AS7116RDX Lockerstor systems. It targets administrators who need error-correcting memory to protect data integrity in multi-user storage workloads. The modules run at 1.2 V and conform to JEDEC PC4-21300 specifications.

Thermals and power at standard speeds

Without heat spreaders the modules rely on system airflow, drawing 1.2 V at the rated 2666 MT/s speed. ECC operation adds negligible overhead, so power draw and acoustics remain identical to non-ECC UDIMMs in the same chassis. Backward compatibility with 2133 and 2400 MT/s lets the kit run cooler if the platform downclocks automatically.

Behaviour under sustained load

Error correction activates continuously during prolonged file transfers, RAID rebuilds or virtualisation tasks, correcting single-bit errors without halting the system. The dual-rank 2Rx8 organisation maintains full bandwidth across all populated slots during extended operations. No thermal throttling occurs because the modules operate within standard DDR4 voltage and timing envelopes.
