QNAP 4GB DDR3-1600 204-Pin SODIMM Memory Module

The QNAP RAM-4GDR3-SO-1600 is a 4 GB DDR3 memory module built for QNAP NAS units that accept a 204-pin SO-DIMM slot. Running at 1600 MT/s (PC3-12800), it gives your NAS the extra headroom it needs to keep services responsive and multitasking smooth.

With more memory in place, file sharing, scheduled backups, media streaming, and even light virtualization can happen at the same time without slowing the system. Small offices gain the capacity to serve more users concurrently, while home labs and creative teams enjoy faster thumbnail generation and quicker access to large photo or video libraries.

The module uses a design that is non-ECC and unbuffered, matching the specification shipped in many QNAP systems. Installation is straightforward: power down the NAS, open the chassis, insert the module, and boot back up. The firmware detects the extra memory automatically—no BIOS tweaks or jumper changes are required.

Official compatibility lists include models such as the TS-431XU, TVS-871, TS-531P and several others that share the same slot type and speed. If your enclosure appears on that list, this upgrade offers a cost-effective way to extend its useful life and keep workloads running smoothly.
