NEMIX RAM 32GB (2x16GB) DDR4 2666 ECC Unbuffered UDIMM CL19 1.2V 288-pin Synology RS2821RP+

32GB DDR4 ECC Kit for Synology RS2821RP+

This 32GB kit contains two 16GB DDR4 2666 modules built for the Synology RackStation RS2821RP+. ECC unbuffered UDIMM design adds error correction for data integrity in NAS workloads. CL19 latency and 1.2V operation match the platform specifications. The 288-pin form factor fits the system memory slots directly.

Replaces lower-capacity or non-ECC modules

Upgrading from smaller DIMMs or standard memory adds both capacity and error correction in one step. The jump is worth it when the NAS runs virtual machines, containers or ZFS pools that benefit from extra headroom and corrected single-bit errors. Existing 16GB or 8GB sticks can be removed to make room for this matched pair.

Fits the RS2821RP+ memory slots

Two UDIMM slots accept this 2Rx8 kit without adapters or risers. No heat spreader means clearance stays minimal inside the rack chassis. The kit frees the installer from mixing speeds or ranks because both modules are validated together. Remaining expansion depends on the number of slots the mainboard provides.
