Compatible 64GB kit for QNAP NAS

This 64GB kit contains four 16GB DDR4 SO-DIMM modules rated at 2400MHz with CL17 timings. It is built specifically for QNAP TS-473 and TS-673 series servers including the 4G and 8G variants. The modules are non-ECC, unbuffered, and operate at a standard 1.2V. They fill all four memory slots in the supported systems for a complete upgrade.

Thermals and power in daily use

Running at 1.2V, these sticks draw minimal power and generate little heat during typical NAS workloads such as file serving or backup. No heat spreaders are fitted, so airflow inside the chassis handles cooling passively. The modules run silently with no moving parts, and the low voltage helps keep overall system power draw down.

Upgrade path and when it matters

This kit replaces the factory-installed memory in the listed QNAP models, taking the system to its 64GB maximum across four sockets. The jump is worthwhile when running virtual machines, containers, or heavy multitasking that exceeds the default capacity. Buyers who need ECC error correction or speeds above 2400MHz cannot use this kit.

Questions about this item

How do I install the four 16 GB DDR4 2400 SODIMM modules in a QNAP TS-473 or TS-673, and which step is most often missed?

Power off the NAS, open the chassis, insert each 260-pin stick firmly until the side clips click, then populate all four slots in matched pairs so the system runs at the rated 2400 MHz CL17 speed.

What maintenance or replacement will this 64 GB kit need over time?

The modules are unbuffered non-ECC DDR4 with no heat spreaders; they require no scheduled maintenance, and a lifetime exchange warranty covers manufacturing defects if a stick ever fails.

What limit appears first when the NAS runs sustained workloads with this memory?

The CAS 17 latency at 2400 MHz and the four-slot 64 GB maximum capacity are the primary bottlenecks; all modules operate at 1.2 V without ECC error correction.
