Capacity 16GB (2 x 8GB)

  • 16GB ECC kit doubles DS1522+ capacity for heavier workloads
  • DDR4 2666 CL19 matches system spec for stable operation
  • JEDEC and RoHS compliant ensures warranty-safe upgrade
  • Backward compatible with 2400 and 2133 speeds
  • Unbuffered 1Rx8 SODIMMs install easily in both slots

Designed for Synology DS1522+

This 16GB kit contains two 8GB DDR4 ECC SODIMM modules built specifically for the Synology DiskStation DS1522+. It targets NAS owners who need reliable memory expansion for virtualization, container workloads or heavy multi-user file serving. The unbuffered design matches the platform requirements exactly.

ECC and 2666MHz CL19 specification

Each module runs at 2666MHz with a CAS latency of 19 and operates at 1.2V. The 260-pin form factor and ECC support are the single specifications that determine compatibility; non-ECC or registered DIMMs will not function in this system. Backward compatibility with 2400MHz and 2133MHz buses is included.

Low-voltage operation without spreaders

At 1.2V the modules draw minimal power and generate little heat, allowing passive cooling inside the compact NAS chassis. No heat spreaders are fitted, so airflow from the system fans is sufficient for normal continuous operation. Acoustic impact is negligible in typical rack or desktop placement.

Questions about this item

What does the 2666 MHz rating mean once the modules are installed in a Synology DS1522+?

The kit runs at 2666 MHz (PC4-21300) with CL19 latency. In the DS1522+ it delivers that speed natively, and will also operate at 2400 MHz or 2133 MHz if the system requires a lower frequency.

Which memory standard and form factor does this kit use, and what does that limit?

It uses 260-pin DDR4 ECC unbuffered SODIMM. The SODIMM form factor fits only laptops, micro servers and NAS units with SO-DIMM slots; it cannot be used in full-size DIMM motherboards.

What physical space and slot layout are needed to install both 8 GB sticks?

Two adjacent 260-pin SO-DIMM slots are required. Each module is a standard-height stick without a heat spreader, so it clears typical NAS chassis lids and nearby components.
