Targeted NAS Upgrade

This 32GB DDR5 module is built specifically for the QNAP TS-H1677AXU-RP NAS. It delivers a direct memory expansion for that platform without requiring configuration changes. The single DIMM format allows incremental scaling across available slots.

Build Integration

The 288-pin UDIMM fits standard DDR5 desktop sockets and operates at 1.1V. Unbuffered, non-ECC operation means it works with consumer-grade memory controllers found in the target NAS. No heat spreader is present, so airflow across the PCB handles thermal dissipation.

Sustained Operation

Rated at 4800 MT/s with CL40 latency, the module maintains JEDEC-standard timing under continuous workloads. Major OEM DRAM from Samsung, Micron or Hynix and per-module stress testing support stability during long file-serving or virtualisation sessions. The 2Rx8 organisation provides density without registered buffering overhead.

Questions about this item

Will the 2Rx8 rank configuration hit the QNAP TS-H1677AXU-RP slot limit before I reach the total capacity I want?

Each slot accepts one 32 GB 2Rx8 module; the NAS motherboard determines how many slots are available for your target capacity.

How much heat does a 1.1 V DDR5 4800 CL40 UDIMM add when the system runs continuously?

The module operates at 1.10 V with no heat spreader, so airflow across the PCB is the only cooling it needs during sustained loads.

Does the TS-H1677AXU-RP require anything beyond an empty 288-pin DDR5 slot to use this memory?

The NAS must support DDR5 4800 non-ECC unbuffered UDIMMs; no extra hardware or cables are required beyond a compatible slot.
