Black Diamond Memory BD32G2133MQR96 32GB DDR4 2133 ECC Registered 4Rx4 server RAM

32 GB DDR4 2133 ECC registered server module

This 32 GB DDR4 2133 module uses a 4Rx4 registered ECC design with a heat spreader. It is built for servers and workstations that require error correction and signal buffering. The 288-pin form factor fits compatible DDR4 DIMM slots. Buyers who need non-ECC unbuffered memory for consumer boards should look elsewhere.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors and detects multi-bit errors to maintain data integrity under prolonged workloads. The heat spreader helps dissipate thermal energy during extended duty cycles. Systems that cannot address 4Rx4 organisation will not be able to use this module.

DDR4 2133 interface limits

The DDR4 2133 (PC4 17000) interface caps bandwidth at the JEDEC standard rate for this speed grade. Latency and throughput are bounded by the 2133 MT/s clock and the registered command/address path. Platforms limited to lower DDR4 speeds will downclock the module automatically. Boards that only support 1Rx8 or 2Rx8 densities cannot populate this 4Rx4 DIMM.
