32GB DDR4 ECC UDIMM for QNAP NAS

This single 32GB DDR4 2666 module adds ECC protection to compatible QNAP TS-h series rackmount and desktop NAS units. It targets administrators who need error-correcting memory for data integrity in ZFS or virtualisation workloads. The unbuffered 2Rx8 design matches the OEM specification for the listed models.

Tool-free DIMM slot installation

The 288-pin UDIMM seats in standard DDR4 slots without cables or brackets. Most QNAP chassis expose the slots after removing a side panel or cover. The only common issue is mixing this ECC stick with non-ECC modules, which disables error correction across the channel.

32GB capacity with 2666 MT/s headroom

One module delivers 32GB at PC4-21300 CL19 1.2V, and the JEDEC profile falls back to 2133 or 2400 MT/s if the platform requires it. Capacity scales by populating additional slots up to the system maximum. Workloads exceeding the installed total will page to storage, reducing throughput.
