32GB DDR4 SODIMM kit for QNAP TVS-673 and TVS-873

This kit supplies 32GB of DDR4 2400 memory across four 8GB modules. It targets owners of the listed QNAP NAS models who need to reach the maximum supported capacity. The non-ECC unbuffered design matches the platform's memory controller requirements.

260-pin unbuffered modules without heat spreaders

Each stick uses a standard 260-pin SODIMM form factor and runs at 1.20V. The low-profile build fits tight NAS slots without clearance issues. Major OEM chips from Samsung, Micron or Hynix are used depending on production batch.

DDR4 2400 CL17 limits bandwidth to PC4-19200

The JEDEC-standard 2400 MT/s rate and CL17 latency set the throughput ceiling for this platform. Builders who need higher memory speeds or ECC error correction must choose a different NAS model that supports those features.

Questions about this item

What DDR4 standard and speed does this 260-pin SODIMM kit use?

The kit runs at DDR4 2400, also marked as PC4-19200, with a CAS latency of CL17 and operates at 1.2 V.

What physical slot and module count are required for the TVS-673 and TVS-873?

Each module is a 260-pin DDR4 SODIMM; the kit includes four 8 GB sticks to fill the four slots in the TVS-673 or TVS-873.

How is the memory installed and which step is often missed?

Power off the NAS, remove the chassis cover, insert each SODIMM at an angle until the gold contacts disappear, then press down until the side clips click. People often forget to seat both clips fully.
