128GB DDR5 kit for QNAP TS-H1277AXU-RP

This 128GB kit contains four 32GB DDR5 4800 UDIMM modules built for the QNAP TS-H1277AXU-RP NAS. It targets administrators who need the maximum supported memory for virtualization, container workloads or large ZFS caches.

Verify DDR5 UDIMM slots and non-ECC support

Before ordering confirm the NAS has four free 288-pin DDR5 UDIMM slots and that the firmware accepts non-ECC unbuffered memory. The modules run at 1.1V with CL40 latency and are organised as 2Rx8 dual-rank chips.

Replaces smaller or slower DDR5 configurations

The kit replaces any lower-capacity DDR5 4800 kit or mixed-speed modules currently installed. The upgrade is worthwhile when the NAS hits memory limits during heavy multi-user file serving, VM hosting or deduplication tasks.

Points forts

  • 128 GB total capacity across four 32 GB modules

Questions sur cet article

Does the kit include all four 32 GB modules or do I need to buy additional sticks?

The kit ships with four 32 GB modules for a total of 128 GB, so no extra sticks are required.

Why choose the CL40 4800 MHz version instead of a lower-latency kit?

CL40 at 4800 MHz matches the QNAP TS-H1277AXU-RP memory controller specification, ensuring stable operation without manual tuning.

Will the 1.1 V 2Rx8 DDR5 modules run at the rated 4800 MHz in my TS-H1277AXU-RP?

Yes, the 1.1 V 2Rx8 DDR5 UDIMMs are validated for 4800 MHz operation in the TS-H1277AXU-RP and will run at that speed automatically.
