Overview

The Synology RAM1600DDR3L-8GBX2 is a 16GB memory upgrade kit consisting of two matched 8GB DDR3L SO-DIMM modules running at 1600 MHz (PC3L-12800) with a CAS latency of CL15. Designed specifically for Synology's DiskStation DS1517+ and DS1817+ network-attached storage units, this kit allows NAS owners to significantly expand their system memory to support more demanding workloads such as running virtual machines via Synology's Virtual Machine Manager, hosting Docker containers, or serving a larger number of concurrent users and applications.

As a genuine Synology-branded product, this memory kit has been tested and validated for full compatibility with supported models, which is an important consideration given that some third-party memory modules can cause instability or fail to be recognized in Synology hardware. The DDR3L specification means these modules operate at a lower 1.35V voltage compared to standard DDR3, contributing to lower power draw and reduced thermal output inside the enclosed NAS chassis. For DS1517+ and DS1817+ owners looking to maximize their NAS capabilities, this kit provides a reliable and supported path to 16GB of system memory.

Pros & Cons

👍 Pros

  • Genuine Synology-branded memory ensures tested compatibility with supported DiskStation models
  • 16GB total capacity across two modules enables demanding NAS applications like virtual machines and heavy multitasking
  • DDR3L low-voltage design runs at 1.35V for reduced power consumption and heat output
  • Sold as a matched pair, eliminating the need to source individually compatible sticks

👎 Cons

  • Only compatible with a limited number of Synology NAS models (DS1517+ and DS1817+)
  • DDR3L is an older memory standard with lower bandwidth than current DDR4 or DDR5 modules
  • Synology-branded memory typically carries a significant price premium over equivalent third-party DDR3L modules
  • CAS latency of CL15 is relatively high for DDR3L-1600 memory

Frequently Asked Questions

This kit is specifically compatible with the Synology DiskStation DS1517+ and DS1817+.
The kit includes two 8GB DDR3L modules for a total of 16GB.
Synology-branded memory is tested and validated for compatibility with their NAS units, which helps avoid potential stability issues and ensures the memory is covered under Synology's support.
DDR3L operates at 1.35V, which is the low-voltage variant of DDR3, consuming less power and generating less heat than standard 1.5V DDR3 modules.
