Targeted NAS Upgrade Kit

This 64 GB kit delivers four 16 GB DDR4 2400 SODIMM modules built specifically for QNAP TVS-673 and TVS-873 units. It addresses the need for higher memory capacity in those appliances without requiring ECC or registered DIMMs.

Drop-in Compatibility

The 260-pin unbuffered sticks operate at 1.2 V and match the PC4-19200 speed grade the NAS expects. No heat spreaders are fitted so they clear tight drive-cage spacing, and the 2Rx8 organisation keeps the memory controller within its supported rank limits.

Sustained Workload Stability

Each module is stress-tested under load before shipping, so file-serving, virtualisation and backup jobs see consistent throughput over long periods. The CL17 latency remains steady during extended multi-user sessions rather than degrading after a short burst.

Questions about this item

Will the CL17 latency at DDR4 2400 become a bottleneck during long NAS workloads?

CL17 at 2400 MT/s is the rated timing; the modules run at 1.20 V without a heat spreader, so sustained throughput stays within JEDEC limits.

How much heat or noise do four 16 GB SODIMMs add when the TVS-673 runs 24/7?

Non-ECC unbuffered DDR4 at 1.20 V draws minimal power and has no moving parts, so the kit adds negligible heat and zero noise inside the chassis.

Which QNAP models must I already own for this 4 x 16 GB kit to be compatible?

The kit is validated for QNAP TVS-673 and TVS-873 NAS units that accept 260-pin DDR4 SODIMMs.
