Server-ready 16 GB DDR4 module

This 16 GB DDR4 2133 ECC RDIMM is built for servers and workstations that require registered memory with error correction. It operates at 1.20 V with a CL15 latency and uses a 2Rx4 rank configuration. The module replaces Crucial CT2K16G4VFD4213, CT16G4VFD4213 and CT2C16G4VFD4213 part numbers.

288-pin DIMM slot requirement

The stick fits a standard 288-pin DDR4 DIMM slot and draws 1.20 V, the normal DDR4 voltage. Registered buffering reduces electrical load on the memory controller, freeing headroom for larger memory populations in multi-socket platforms. ECC circuitry corrects single-bit errors without halting the system.

Sustained workload stability

Registered signalling and on-die ECC keep data integrity intact during long compute runs, virtualization hosting or database serving. The CL15 timing at 2133 MT/s delivers consistent throughput without the voltage headroom that higher-speed bins demand. Modules are tested before shipping to verify reliable operation under continuous load.
