  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS Latency19
  • Voltage1.2V

Capacity 64GB (2 x 32GB)

  • ECC registered design prevents data corruption in servers
  • 64GB kit with two 32GB modules expands memory capacity
  • DDR4 2666 speed with CL19 latency delivers responsive performance
  • 2V low voltage reduces power draw in compatible systems
  • Validated for Synology ActiveProtect DP7200 and DP7400 appliances

Capacity and Form Factor

This OWC kit provides 64GB of DDR4 memory in two 32GB registered DIMMs. Each module uses a 288-pin layout and runs at 1.2V with a CL19 latency rating. The 2Rx4 organisation and ECC registered design target server and workstation platforms.

Suited Systems and Limitations

The modules are validated for Synology ActiveProtect DP7200 and DP7400 appliances. They also operate in systems rated for 2133MHz or 2400MHz DDR4. Standard desktop computers cannot use registered ECC memory, and mixing these sticks with unbuffered or load-reduced DIMMs is not supported.

Decisive Specification

The registered ECC attribute is the single factor that decides compatibility. Only platforms designed for registered DDR4 ECC RDIMMs will accept this kit; consumer motherboards and unbuffered server boards will not.

Soalan tentang produk ini

Does the 288-pin DDR4 RDIMM fit the memory slots on the Synology ActiveProtect DP7200 and DP7400?

Yes, the 288-pin DDR4 2666 registered DIMM is built to the JEDEC standard for those models and installs directly into their RDIMM slots.

What is the correct way to seat both 32 GB modules so the system recognises the full 64 GB?

Power off the unit, open the chassis, align each module's notch with the slot key, press firmly until both side clips click, then power on and verify 64 GB in the Synology DSM memory report.

When should the ECC registered modules be replaced to keep the NAS running reliably?

Replace them if DSM reports correctable ECC errors that climb over time, if the system fails memory self-test at boot, or after a confirmed DIMM fault in the hardware log.
