NEMIX RAM 64GB DDR5 4800 ECC UDIMM Kit

This 64GB kit contains two 32GB DDR5 4800 modules built to PC5-38400 specifications. It targets IT professionals and NAS administrators who need error-correcting memory for the QNAP TS-H1677AXU-RP platform. Each module runs at 1.1V with CL40 latency and uses a 2Rx8 organisation for stable operation under sustained workloads.

QNAP TS-H1677AXU-RP NAS Memory Upgrade

The kit suits buyers who must add 64GB of ECC unbuffered DDR5 to a compatible QNAP NAS and want factory-tested modules from a specialist memory supplier. It is not for buyers who need registered or load-reduced DIMMs, nor for systems that require a heat spreader on every module. The unbuffered design and absence of a spreader mean the memory connects directly to the board without additional cooling hardware.

288-Pin DDR5 ECC UDIMM 1.1V CL40 Specification

The single specification that decides fitment is the 288-pin DDR5 ECC unbuffered UDIMM form factor running at 1.1V with CL40 timing. Only systems that accept this exact module type, voltage and latency will recognise the full 64GB capacity at 4800MT/s. Verify the QNAP TS-H1677AXU-RP motherboard manual before purchase.

Questions sur cet article

Does DDR5 4800 PC5-38400 set the maximum data rate the QNAP TS-H1677AXU-RP can use?

The kit is rated at 4800 MT/s with a PC5-38400 designation; the NAS will operate the modules at the highest speed its memory controller supports.

What physical slot and module height does the 288-pin 32GB UDIMM require in the TS-H1677AXU-RP?

Each module uses a standard 288-pin DDR5 UDIMM form factor without a heat spreader, so it fits the NAS DIMM slots without clearance issues.

What is the correct installation sequence for the two 32GB sticks, and which step is often missed?

Power off the NAS, open the chassis, insert both modules firmly until the latches click, then power on and verify 64GB is recognised in the QTS firmware.
