NEMIX RAM 16GB (2x8GB) DDR4 2400 CL17 SODIMM NAS memory upgrade for QNAP TVS-673 TVS-873

QNAP TVS-673 & TVS-873 memory kit

This 16 GB kit contains two 8 GB DDR4 SODIMM modules built for QNAP TVS-673 and TVS-873 NAS units. It suits administrators who need extra capacity for virtual machines or heavy file services on those specific models. Each module runs at 1.2 V without ECC or buffering. The 260-pin form factor matches the factory slots exactly.

Sustained workload behaviour

Modules are stress tested under load before shipping to verify stability during long backup windows or continuous indexing jobs. Unbuffered DDR4 at CL17 latency keeps timing predictable when the NAS serves multiple users simultaneously. The 1Rx8 rank organisation helps the memory controller maintain steady throughput without rank interleaving delays.

DDR4 SODIMM interface limits

The PC4-19200 rating caps bandwidth at the DDR4 2400 transfer rate even though the platform supports DDR4 2666. Non-ECC operation means single-bit errors are not corrected automatically, so critical databases should use application-level checksums. Builders who need ECC protection or higher density per slot must select a different module specification.
