OWC 512GB DDR4 ECC Registered Kit

This kit provides 512GB of DDR4 2666 memory across sixteen 32GB registered DIMMs. It is built for Synology ActiveProtect DP7200 and DP7400 appliances that require ECC registered modules. The CL19 latency and 1.2V operation match the platform specifications exactly.

Suited for DP7200 and DP7400 upgrades

Buyers expanding a Synology ActiveProtect DP7200 or DP7400 will find full compatibility. Systems that accept only unbuffered or load-reduced ECC memory cannot use these registered DIMMs. Standard desktop motherboards and consumer laptops are also excluded.

JEDEC and RoHS compliance included

The modules meet JEDEC DDR4 standards and RoHS requirements, ensuring a warranty-safe upgrade path. Backward compatibility with 2133MHz and 2400MHz operation allows flexible deployment in mixed-speed configurations. No heat spreaders or additional software are bundled.

Questions about this item

Does my Synology ActiveProtect DP7200 need all 16 slots free to install this 512GB kit?

The kit provides 16 modules of 32GB each, so 16 free 288-pin DDR4 slots are required to install the full 512GB capacity.

Will these 2666MHz registered ECC DIMMs run correctly if my DP7400 currently has 2133MHz modules installed?

The modules are backward compatible with 2133MHz and 2400MHz speeds; the system will operate at the lowest common speed when mixed.

How can I verify the 2Rx4 registered ECC memory is recognised at 2666 CL19 after installation?

Check the Synology DSM memory information page — it should report 512GB total, DDR4 2666, CL19, ECC registered, 2Rx4 organisation.
