Black Diamond Memory BD32GX22133MQR26 64GB (2×32GB) DDR4 2133 ECC Registered server RAM

Server memory kit for enterprise upgrades

This 64 GB kit contains two 32 GB DDR4 modules built for registered ECC server platforms. The 288-pin DIMMs target administrators who need dependable capacity expansion without changing existing infrastructure. Each stick is tested for compatibility across a wide range of qualified systems.

64 GB capacity with quad-rank density

The paired modules deliver 64 GB total using 4Rx4 organisation, giving dense memory footprints for virtualisation hosts and database nodes. Headroom scales with the number of populated slots; once the motherboard's registered DIMM limit is reached, further expansion requires higher-density parts or a platform change.

DDR4 2133 registered ECC interface

The memory runs at DDR4 2133 (PC4 17000) speeds under the registered ECC protocol, which adds a clock cycle for signal buffering and enables single-bit error correction. Bandwidth and latency are bounded by the 2133 MT/s data rate, so workloads demanding higher throughput will hit the interface ceiling before the capacity limit.
