16GB DDR4 ECC UDIMM for Synology NAS

This 16GB DDR4 2133 ECC unbuffered UDIMM is built for Synology RackStation systems that require error-correcting memory. It operates at 1.20V with a CAS latency of CL15 and uses a 2Rx8 rank configuration. The module fits 288-pin DDR4 slots and is validated for compatibility with Synology RAMEC2133DDR4-16G specifications.

Sustained workload stability with ECC

Error-correcting code detects and corrects single-bit errors during continuous operation, preventing data corruption in file-serving and backup workloads. Unbuffered design keeps latency low for the memory controller while the 2Rx8 organisation maintains signal integrity under load. Modules are stress tested under load to verify reliability before shipment.

DDR4 2133 interface limits bandwidth to PC4-17000

The DDR4 2133 interface caps maximum theoretical throughput at PC4-17000, so sustained read and write speeds cannot exceed this ceiling. CL15 timing sets the minimum cycle delay for each column access, defining the latency floor. Systems that require higher memory bandwidth or lower latency will be constrained by this standard.
