OWC 32GB DDR4 2666 PC4-21300 CL19 2Rx8 288-pin 1.2V ECC UDIMM for ASUSTOR AS7112RDX AS7116RDX

32GB DDR4 ECC UDIMM for ASUSTOR NAS

This 32GB DDR4 2666 ECC UDIMM is built for ASUSTOR AS7112RDX and AS7116RDX systems. It targets administrators who need to expand memory capacity in these rackmount NAS units. The single module delivers 32GB at CL19 latency and operates at 1.2V. It is a JEDEC-standard component designed for server and NAS workloads.

Check slot count and current population

Verify how many of the 288-pin DDR4 slots are free in your ASUSTOR unit before ordering. The module is unbuffered ECC and uses a 2Rx8 organisation, so the system must accept that rank configuration. Existing memory should be DDR4 running at 2666, 2400 or 2133 MHz to match the supported speeds. Mixing registered or load-reduced DIMMs with this unbuffered stick will prevent boot.

Steady throughput under continuous NAS load

Under sustained file-serving or virtualisation workloads the module maintains its rated 2666 MT/s without throttling. ECC circuitry corrects single-bit errors on the fly, preserving data integrity during long backup or replication jobs. The absence of a heat spreader means airflow across the DIMM is required; ensure the chassis fans are functional. Voltage remains at 1.2V throughout extended operation.
