QNAP NAS memory upgrade

This 16 GB DDR4 SODIMM is built for QNAP TVS-673e and TVS-873e NAS units. It targets administrators who need more capacity for virtualization or heavy file workloads. The module runs at 2400 MT/s with CL17 latency at 1.20 V. It fits the 260-pin SODIMM slots in those specific models.

Single-module kit simplifies installation

The package contains one 16 GB stick so you can populate a single empty slot or match an existing module. No extra cables, brackets or software licences are included. The unbuffered non-ECC design means the NAS treats it as standard system memory. Installation follows the standard SODIMM procedure described in the QNAP manual.

DDR4 SODIMM limits apply

The 260-pin DDR4 interface caps transfer rate at the JEDEC 2400 standard used here; faster DDR4 modules will downclock to this speed. Non-ECC operation offers no error correction for critical data. The 2Rx8 organisation occupies one rank per channel, so total system rank limits on the NAS motherboard still apply.

Questions about this item

Will the 16GB DDR4 2400 SODIMM need replacement as my QNAP TVS-673e workloads grow?

The module is a fixed 16GB capacity; if your NAS later requires more memory you would add or replace modules rather than service this stick.

What limit appears first when the TVS-873e runs this CL17 2Rx8 kit at full load for hours?

The 2400 MT/s data rate and CL17 latency set the throughput ceiling before thermal or power limits become a factor.

How much heat and power does the 1.20 V 260-pin SODIMM produce during all-day operation in a QNAP NAS?

At 1.20 V the module draws minimal power and runs without a heat spreader, so it adds little heat to the chassis.
