QNAP NAS Memory Upgrade

This 8 GB DDR4 SODIMM module is built for QNAP TS-332X, TS-473, TS-673, TS-832PX and TS-832X NAS units. It delivers a simple capacity increase for workloads that benefit from extra memory headroom.

260-Pin DDR4 2666 CL19 Module

The stick fits a standard 260-pin SO-DIMM slot and runs at 1.2 V with CL19 latency. It is unbuffered, non-ECC and single-rank 1Rx8, requiring no extra configuration in compatible bays. Backward compatibility with 2400 and 2133 MHz systems allows it to slot into older platforms that share the same socket.

Sustained Operation Without Heat Spreader

JEDEC and RoHS compliance ensures stable voltage and timing during extended file transfers or virtualisation tasks. The bare-board design relies on chassis airflow rather than a spreader, so sustained throughput stays consistent when the enclosure provides adequate cooling. Buyers needing ECC error correction or registered signal buffering should look elsewhere.

Questions about this item

Will the 2666 MHz speed and CL19 latency limit performance during sustained NAS workloads?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency, matching the JEDEC standard for this speed grade.

How much heat or power does the 1.2 V unbuffered SODIMM generate when the NAS runs 24/7?

Operating at 1.2 V without a heat spreader, the 1Rx8 Non-ECC SODIMM draws minimal power and produces low heat typical for DDR4 laptop-class modules.

Which QNAP models must I already own for this 260-pin DDR4 SODIMM to work?

Compatible systems include QNAP TS-332X, TS-473, TS-673, TS-832PX, TS-832X and TS-464-4G.
