128GB DDR5 4800 UDIMM kit for QNAP TS-H3077AFU

This NEMIX RAM kit delivers 128GB across four 32GB unbuffered DDR5 modules rated at 4800 MT/s with CL40 latency. It is built specifically for the QNAP TS-H3077AFU all-flash NAS and uses 1.1V 288-pin UDIMMs without ECC or heat spreaders.

Suits administrators expanding that NAS

The four-module layout fills every slot in the supported system, so buyers needing only a partial upgrade or requiring ECC error correction should consider other configurations. Systems limited to lower DDR5 speeds or different form factors cannot accept this kit.

4800 MT/s DDR5 speed and CL40 timing

The modules operate at PC5-38400 with a CAS latency of 40, which the target NAS expects for stable operation. Verify that the platform firmware supports this exact data rate before installation.

Questions about this item

Which capacity kit should I choose for my QNAP TS-H3077AFU?

This kit provides 128GB total using four 32GB modules, matching the maximum supported configuration for the TS-H3077AFU.

What does DDR5 4800 CL40 mean for real workloads on this NAS?

The modules run at 4800 MT/s with CL40 timing at 1.10V, delivering the rated bandwidth of PC5-38400 for file serving and virtualization.

Does the 288-pin UDIMM interface limit speed or capacity in this system?

The 288-pin DDR5 UDIMM form factor is the native slot type for the TS-H3077AFU, so the 4800 MT/s speed and 128GB capacity are fully supported.
