Server Memory Kit

This 128GB kit contains two 64GB DDR4 2933 registered ECC modules built for enterprise servers and workstations. The 4Rx4 organisation and PC4 23400 rating suit high-density memory channels in multi-socket platforms. Black Diamond Memory validates the parts across a wide range of qualified systems.

Compatibility Check

Confirm that your motherboard accepts 288-pin DDR4 registered DIMMs and supports 4Rx4 modules at the 2933 MT/s data rate. The platform must enable ECC functionality and provide enough DIMM slots for the two-module population. Verify the maximum supported capacity per channel before ordering.

Registered ECC Benefit

The registered buffer reduces electrical load on the memory controller, allowing larger populations without signal degradation. On-die ECC detects and corrects single-bit errors to protect data integrity in critical workloads. These features together let the kit operate reliably in dense server configurations.
