Computer Memory Solutions 64GB (4x16GB) DDR4 2400 CL17 SODIMM memory upgrade

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.
