Two green 288-pin DDR5 UDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 32GB (2x16GB) DDR5 4800 CL40 1.1V UDIMM QNAP TS-H1677AXU-RP memory upgrade

SKU CH-282K-N9H3J

A 32 GB DDR5 kit with two 16 GB unbuffered UDIMMs at 4800 MT/s CL40, 1.1 V, validated for the QNAP TS-H1677AXU-RP NAS

  • Capacity32GB (2 x 16GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCNo
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V

Capacity 32GB 2X16GB

  • 32 GB kit expands QNAP TS-H1677AXU-RP capacity
  • DDR5 4800 MT/s raises memory bandwidth for NAS workloads
  • CL40 1.10 V timing keeps power draw low
  • 288-pin UDIMM fits QNAP DDR5 slots directly
  • Two 16 GB modules enable dual-channel operation

Compatible QNAP NAS Upgrade

This 32 GB kit uses two 16 GB DDR5 4800 modules built for the QNAP TS-H1677AXU-RP. The 1.10 V unbuffered UDIMMs install without ECC or registration requirements. IT teams select this memory to expand capacity for virtualisation and heavy file workloads.

Straightforward DIMM Installation

The 288-pin DDR5 sticks seat in standard UDIMM slots and need no extra configuration beyond the system firmware. CL40 timing is applied automatically at 4800 MT/s. Mistakes happen when slots are populated in the wrong order or when mixed with existing modules of different rank or voltage.

Steady Throughput Under Load

Rigorous stress testing confirms stable operation during sustained multi-threaded tasks such as backup deduplication and container hosting. The 1Rx8 organisation and major OEM chips maintain consistent bandwidth without throttling. Workloads needing ECC protection or higher frequencies are not addressed by this kit.

Questions about this item

How can I confirm the NEMIX RAM kit is running at DDR5 4800 CL40 after installing it in my QNAP TS-H1677AXU-RP?

Enter the NAS BIOS or use the QNAP system information panel to verify the memory speed reads 4800 MT/s and the CAS latency shows CL40 at 1.10 V.

What exactly ships in the package and is anything else required to complete the upgrade?

The box contains two 16 GB 288-pin DDR5 UDIMM modules for a total of 32 GB; no additional parts or cables are needed for installation.

Should I choose this 32 GB kit or a different capacity for the TS-H1677AXU-RP?

This 32 GB kit (2×16 GB) matches the validated DDR5 4800 CL40 specification for the TS-H1677AXU-RP; select it when 32 GB is the desired total capacity.
