OWC 32GB (4x8GB) DDR4 2666 ECC UDIMM memory upgrade

OWC 32GB DDR4 ECC kit for ASUSTOR NAS

This kit contains four 8 GB DDR4 2666 ECC unbuffered UDIMMs validated for the ASUSTOR AS7112RDX and AS7116RDX. It is intended for owners of those rack-mount NAS units who need error-correcting memory to protect stored data. Builders using consumer motherboards without ECC support cannot use the error-correction feature.

Tool-free DIMM installation with ECC caveats

The modules fit standard 288-pin DDR4 slots and require no special tools; the supplier notes that most users complete the upgrade themselves. The sticks have no heat spreaders, so they sit low in tight drive bays. If the NAS BIOS does not enable ECC, the modules will still run but without error correction, negating their primary benefit.

Steady 2666 MT/s operation at 1.2 V

Rated CL19 at 2666 MT/s (PC4-21300), the memory maintains its JEDEC-standard timings under continuous NAS workloads such as RAID rebuilds or long backup streams. The 1.2 V operating voltage keeps power draw predictable during sustained multi-hour tasks. Modules also down-clock to 2400 or 2133 MT/s if the system requires it.
