Rank 1Rx4

  • 32 GB total capacity across four 8 GB modules
  • DDR4 2666 MHz PC4-21300 speed with CL19 latency
  • ECC registered design detects and corrects data errors
  • 2 V low-voltage operation reduces power draw
  • Compatible with Synology SA3400 SA410 SA3600 SA3610 NAS systems

Targeted NAS Upgrade

This 32GB kit contains four 8GB DDR4 2666 ECC registered RDIMMs built for Synology SA3400, SA410, SA3600 and SA3610 servers. It suits administrators who need validated capacity expansion for those specific NAS models. The modules will not work in standard desktop PCs or with unbuffered and load-reduced memory types.

Thermal and Power Profile

Each module operates at 1.2V with CL19 latency and no heat spreader, relying on the chassis airflow typical of 1U and 2U rackmount NAS units. Registered buffering adds minimal electrical load while the low voltage keeps power draw modest inside the approved Synology platforms.

Compliance and Support Benefits

JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications for the listed servers. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme so a failed module can be swapped without downtime.

Questions about this item

How do I install the 288-pin DDR4 RDIMMs in my SA3600, and which slot order avoids the single-channel mistake?

Power down the NAS, open the chassis, and seat each of the four 8 GB modules firmly until the retention clips click. Populate all four slots so the kit runs in dual-channel mode; leaving any slot empty forces single-channel operation.

What maintenance will the ECC registered modules need over their service life?

No scheduled maintenance is required. The modules have no heat spreaders or moving parts; keep the NAS air filters clean so the 1.2 V DIMMs stay within thermal limits.

What limit appears first when the SA3400 runs sustained workloads at 2666 MT/s?

The memory controller caps throughput at the JEDEC 2666 MT/s CL19 rating, so sustained bandwidth tops out there regardless of how long the load runs.
