QNAP TS-H1677AXU-RP memory upgrade

This 16GB DDR5 module is built specifically for the QNAP TS-H1677AXU-RP NAS. It runs at 4800 MT/s with a CAS latency of CL40 and operates at 1.1V. The single-rank 1Rx8 unbuffered design uses major OEM chips from Samsung, Micron or Hynix and fits a standard 288-pin UDIMM slot.

NAS administrators adding capacity

Administrators who need to expand the memory of a TS-H1677AXU-RP will find this module validated for that platform. It is not suitable for systems that require ECC error correction, registered buffering or a different DDR generation, and it lacks a heat spreader for builds that demand one.

Sustained NAS workloads

All modules are stress tested under load to verify stability during continuous file serving, virtualization or backup tasks. The 1.1V operating voltage keeps power draw consistent over long periods, and the unbuffered topology avoids extra latency in steady-state operation.

Perguntas sobre este artigo

Will my QNAP TS-H1677AXU-RP accept this 16 GB DDR5 4800 UDIMM without any other hardware changes?

Yes — the module is built for that NAS and plugs straight into a free 288-pin DDR5 slot; no extra parts are required.

Can I leave the original memory in place and add this 1Rx8 CL40 stick to the remaining slots?

The NAS supports mixed populations, so you can keep the factory modules and add this 16 GB DDR5 4800 stick in an empty slot.

After installation, how do I confirm the new 16 GB DDR5 4800 module is recognised at 4800 MT/s?

Open the QNAP web UI, go to System Information → Memory, and verify the total shows the extra 16 GB running at 4800 MT/s.
