128 GB DDR5 4800 kit for QNAP TS-H1677AXU-RP

This 128 GB kit contains four 32 GB DDR5 4800 UDIMM modules built for the QNAP TS-H1677AXU-RP NAS. Each module runs at 1.1 V with CL40 latency and a 2Rx8 organisation. The kit is validated for that specific system.

Suits administrators expanding a single compatible

The memory fits only the listed QNAP model; it will not work in other NAS units, servers, workstations or desktop motherboards that require ECC, registered DIMMs or a different pin count. Buyers needing ECC protection or a different form factor should look elsewhere.

DDR5 4800 288-pin UDIMM at 1.1 V

The modules use the DDR5 4800 (PC5-38400) standard with a 288-pin unbuffered UDIMM interface and operate at 1.10 V. This specification decides whether the kit matches the memory slots and voltage requirements of the target NAS.

Questions about this item

Will the four 32 GB DDR5 4800 CL40 modules run alongside any existing DDR5 sticks I keep in my QNAP TS-H1677AXU-RP?

The kit is validated for the TS-H1677AXU-RP; mixing with other DDR5 modules is possible only if they share the same 4800 MT/s speed, CL40 latency, 1.1 V voltage and 2Rx8 organisation.

How can I confirm the 128 GB kit is recognised at 4800 MT/s with CL40 timings after installation?

Boot the NAS, open the QTS Resource Monitor or System Information panel and verify the memory section shows 128 GB total, 4800 MHz operating speed and CL40 latency values.

What exactly ships in the box and is anything else required for the upgrade?

The package contains four 32 GB 288-pin DDR5 UDIMM modules; no heat spreaders, cables, tools or additional parts are included or needed for installation.
