OWC 32GB (2x16GB) DDR4 2666 ECC UDIMM for Synology SA3200D memory upgrade

SKU CH-XWBX-ZPD7Y

32 GB kit of two 16 GB DDR4 2666 ECC UDIMM modules for Synology SA3200D

  • Capacity32GB (2 x 16GB)
  • Type288-Pin DDR4 ECC UDIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes

Capacity 32GB (2 x 16GB)

  • ECC protection guards data integrity on your Synology SA3200D
  • 32 GB kit (2 × 16 GB) doubles capacity for heavy workloads
  • DDR4 2666 CL19 at 1.2 V matches system specifications exactly
  • Unbuffered 288-pin UDIMM installs in minutes with no tools needed
  • JEDEC and RoHS compliant for a warranty-safe upgrade

Capacity and configuration

This kit provides 32 GB of DDR4 memory in two 16 GB modules. Each stick is a 288-pin ECC UDIMM rated at 2666 MHz with CL19 latency and 1.2 V operation. The 2Rx8 rank layout matches the requirements of the Synology SA3200D RackStation.

Suitable buyers and limits

The kit is built for administrators upgrading a Synology SA3200D who need error-correcting unbuffered memory. It will not suit systems that require registered or load-reduced DIMMs, nor platforms that only accept non-ECC modules. Buyers needing more than 32 GB or a different speed grade should look at other validated options.

Installation notes

Installation is a straightforward DIMM swap inside the NAS chassis; no tools beyond a screwdriver are typically needed. The modules have no heat spreader, so they fit tight drive-bay clearances. The most common issue is seating both sticks fully so the latches click, otherwise the system will not recognise the added capacity.

Questions about this item

What must my Synology SA3200D already support for this 32GB DDR4 2666 ECC UDIMM kit to work?

The NAS must accept 288-pin DDR4 ECC unbuffered UDIMMs at 1.2V. The kit provides two 16GB modules running at 2666MHz CL19 (PC4-21300) in a 2Rx8 configuration.

Will these 2666MHz modules run correctly if my SA3200D currently uses 2133MHz or 2400MHz memory?

Yes. The modules are backward compatible with 2133MHz and 2400MHz systems and will operate at the highest speed the platform allows.

How can I confirm the kit is running at the correct 2666MHz speed and ECC function after installation?

Check the Synology DSM Resource Monitor or system information page; it will display 32GB total capacity, 2666MHz operating speed, and ECC status as active.
