QNAP TS-H1277AXU-RP memory kit

This NEMIX RAM kit provides 64 GB of DDR5 memory across two 32 GB modules. It is built specifically for the QNAP TS-H1277AXU-RP NAS and runs at 4800 MT/s with CL40 timing at 1.1 V. The unbuffered non-ECC UDIMM design uses major OEM chips from Samsung, Micron or Hynix.

Ideal for NAS owners needing maximum capacity

The dual-rank 2Rx8 layout suits the TS-H1277AXU-RP when all slots are populated with 32 GB modules. It is not for systems that require registered ECC memory, nor for boards limited to single-rank or lower-density DDR5 DIMMs. Buyers who need error-correcting code support or registered modules should look elsewhere.

Straightforward DIMM installation

The 288-pin DDR5 UDIMMs slot into the NAS memory sockets without tools or cables. Because the kit is validated for the target model, compatibility issues are rare; the main risk is seating a module incompletely, which can prevent the system from posting. Following the NAS manual ensures correct orientation and firm insertion.

Perguntas sobre este artigo

Does this kit need an empty 288-pin DDR5 UDIMM slot on the QNAP TS-H1277AXU-RP to install?

Yes, each 32 GB module plugs into a standard 288-pin DDR5 UDIMM slot; the kit includes two modules so two free slots are required.

Will the DDR5 4800 CL40 modules run at their rated speed if I keep slower DDR5 already installed in the NAS?

The system will clock all installed memory to the lowest common speed; mixing slower modules will cause this kit to operate below 4800 MT/s.

How can I confirm the NAS recognises the full 64 GB kit at 4800 MT/s after installation?

Check the QNAP firmware memory information page — it should show 64 GB total capacity and a memory speed of 4800 MT/s with CL40 timings.
