Compatible QNAP NAS upgrade

This 32GB DDR4 SODIMM is built for QNAP TVS-672X, TVS-672XT, TVS-675, TVS-872X and TVS-872XT systems. It installs as a single module to expand memory capacity for virtualization, file serving and multi-user workloads. The 260-pin form factor fits the SO-DIMM slots in these NAS units without modification. Builders needing ECC registered memory or a different capacity should look elsewhere.

JEDEC standard voltage and timings

The module runs at the standard 1.2V DDR4 voltage with CL19 latency at 2666 MT/s. It is an unbuffered, non-ECC design that operates within JEDEC specifications for typical NAS operating temperatures. No heat spreader is fitted, so airflow through the chassis handles thermal dissipation during normal multi-tasking. Power draw stays at the low level defined for 1.2V SO-DIMM parts.

Sustained load stability in NAS roles

Under continuous workloads such as Docker containers, backup jobs or database caching, the memory maintains its rated 2666 MT/s speed without throttling. The 2Rx8 organisation provides density for large datasets while the JEDEC-compliant timings keep error rates low during extended operation. Backward compatibility with 2400 and 2133 MT/s platforms allows the same module to downclock automatically if a compatible system requires it.

この商品に関する質問

How do I install the 260-pin SODIMM into my QNAP TVS-872XT and what step is often missed?

Power off the NAS, unplug it, open the chassis, align the notch on the 260-pin module with the slot key, press firmly until the side clips click, then replace the cover before restoring power.

What maintenance or replacement will this 32GB DDR4 module need later?

No scheduled maintenance is required; the module has no heat spreader and uses standard 1.2V DDR4, so it runs passively and only needs replacement if a memory error appears.

What limit appears first on this CL19 2666MHz kit during sustained heavy workloads?

The CAS latency of 19 cycles at 2666MHz sets the access timing ceiling, so latency-bound tasks hit that timing wall before bandwidth saturates.
