QNAP RAM-4GDR3L-SO-1600 4GB DDR3L SO-DIMM Memory Module

Overview

The RAM-4GDR3L-SO-1600 is a 4GB DDR3L SO-DIMM module running at 1600 MHz, sourced direct from QNAP to expand the working memory of compatible QNAP NAS appliances. More RAM directly translates to better concurrent-user throughput, smoother simultaneous virtualisation workloads, and reduced I/O latency under heavy surveillance recording or multi-application workloads — the cases where a factory-default memory configuration becomes the bottleneck first. If your NAS is sluggish under peak load or you are enabling additional QNAP packages (Container Station, Virtualization Station, or resource-heavy surveillance apps), this module is the targeted fix.

Compatibility

This module is designed for QNAP NAS systems that accept DDR3L SO-DIMM memory at 1600 MHz. QNAP's own memory compatibility documentation specifies which chassis support user-installable RAM expansion — consult the official QNAP memory compatibility list for your exact NAS model before ordering. DDR3L operates at 1.35V (versus standard DDR3 at 1.5V), so verify your target unit supports the lower-voltage standard; most QNAP NAS platforms released during the DDR3 generation do, but confirm before purchasing. This module is not cross-compatible with DDR4 slots or full-size DIMM sockets.

Installation Notes

Power down the NAS completely and disconnect the power cable before accessing the memory bay — hot-swap memory installation is not supported. SO-DIMM modules seat at an angle and click flat into the retention clips; do not force the module. A single-module install is valid, but check your unit's documentation for preferred slot population order if installing alongside an existing module. After reseating the lid and powering on, confirm the new total RAM is recognised in the QNAP system information dashboard before returning the unit to service.
