QNAP 4GB DDR4 2666MHz SO-DIMM T1 Version Memory Module

The QNAP RAM-4GDR4T1-SO-2666 is a memory module that offers 4 GB of DDR4 capacity and runs at 2666 MT/s in a 260-pin SO-DIMM format. It is built for devices that rely on DDR4 SO-DIMM architecture, including QNAP TS-x64 series NAS units, many notebooks, and a wide range of compact PCs.

This module operates at 1.2 volts, a specification that helps keep power draw modest and heat output low, an advantage in NAS enclosures and slim laptop chassis where airflow can be limited. Because it is unbuffered and non-ECC, installation is straightforward: just slot it into the available SO-DIMM socket, power on the system, and the additional memory becomes available without extra configuration.

In a QNAP NAS environment, extra RAM improves response times when multiple users access shared folders, run virtual machines, or stream high-resolution media. Administrators who enable snapshot protection or containerized applications will notice smoother performance and fewer slowdowns during peak demand. Notebook and mini-PC users can expect quicker application launches, better browser multitasking, and less paging to storage when working with large files.

The module can be paired with another identical stick to reach 8 GB or combined with higher-capacity modules to reach the system’s maximum of 16 GB across two SO-DIMM slots, provided the host device supports the configuration. Always verify the motherboard or NAS compatibility list before upgrading.
