32 GB DDR4 ECC UDIMM for NAS

This module adds 32 GB of DDR4 ECC unbuffered memory to compatible QNAP NAS devices and other systems that accept 288-pin UDIMMs. It targets administrators who need data-integrity protection for file serving, virtualization or backup workloads.

DDR4 2666 CL19 interface limits

The DDR4 2666 (PC4-21300) interface caps peak bandwidth at the JEDEC standard rate for this speed grade. Latency is fixed at CL19 and voltage at 1.20 V, so the module cannot exceed the throughput or timing parameters defined by the DDR4 2666 specification.

32 GB single-module capacity and headroom

A single 32 GB stick fills one slot and suits workloads that fit within that footprint, such as typical NAS services or light virtualization. Systems requiring more than 32 GB total must add additional modules, and the 2Rx8 organisation may limit maximum rank count on some boards.

Questions sur cet article

Is the 32GB single module the only capacity available for this DDR4 2666 ECC UDIMM?

Yes, this part is sold as a single 32GB stick with the 2Rx8 organisation and CL19 timing.

What does the DDR4 2666 (PC4-21300) rating deliver in an actual server?

The module runs at 2666 MT/s with CL19 latency at 1.20V, providing ECC error correction for data integrity under load.

How does the 288-pin DDR4 ECC UDIMM interface limit performance in practice?

The unbuffered 288-pin DDR4 slot caps throughput at the PC4-21300 line rate, so the stick cannot exceed 2666 MT/s even if the board supports faster speeds.
