Synology D4ES03-16G 16GB DDR4 ECC SODIMM — Genuine, Sealed

Brand new, factory sealed. This is the exact Synology-branded module for the current 25-series DiskStations — the one Synology validates so your NAS stays fully supported.

Here's why the part number matters: Synology's own guidance is that installing non-Synology memory can lead to system instability or boot failures, and can leave you without full warranty and technical support. Third-party sticks are cheaper for a reason. This is the genuine article — the one that just works, with no "unverified memory" warning in DSM and no support headaches down the line.

Specs:

  • 16GB DDR4-2666 (PC4-21300) ECC Unbuffered SODIMM, 260-pin
  • Genuine Synology D4ES03-16G — backed by a 5-year Synology warranty
  • Error-correcting (ECC) memory: catches and fixes data errors before they reach your files — the reason you run a NAS in the first place

Confirmed compatible with the 25-series:DS925+, DS1825+, DS1525+, DS725+ and other current models that call for this exact module.(Note: this is NOT the module for older units like the DS923+ — those use the D4ES01/D4ES02. Check your model's memory spec before buying.)

If you're expanding a new DiskStation, this is the plug-it-in-and-forget-it path: pop it in the slot, power up, done. No compatibility roulette, no warranty gray area.

Ships fast and packed to protect the module in transit — check my response. Buy with confidence.
