QNAP TS-H1677AXU-RP memory kit

This 64 GB kit contains four 16 GB DDR5 modules validated for the QNAP TS-H1677AXU-RP NAS. It targets administrators who need to expand system memory for virtualization or heavy multi-user workloads.

DDR5 4800 CL40 1.1 V unbuffered non-ECC

The decisive specification is DDR5 4800 with CL40 latency at 1.1 V in a 288-pin UDIMM form factor. The kit is unbuffered and non-ECC, so it matches only platforms that accept that exact combination.

Tool-less slot installation

Modules insert vertically into the NAS memory slots without tools; the process normally takes a few minutes. The common issue is mixing these sticks with existing memory of a different speed or rank, which can prevent the system from posting.

이 상품에 대한 질문

What does the 4800 MT/s speed mean when installed in the TS-H1677AXU-RP?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated throughput provided the NAS memory controller supports that speed.

How does the DDR5 UDIMM interface affect usable bandwidth in this NAS?

As unbuffered non-ECC DDR5 UDIMMs, they connect directly to the CPU memory channels without a register, so maximum bandwidth is limited by the TS-H1677AXU-RP's own memory controller.

What physical slots and clearance does the 288-pin UDIMM kit require?

The kit contains four 16 GB 288-pin DDR5 UDIMMs that need four standard UDIMM slots; no heat spreader is fitted, so low-profile clearance is sufficient.
