Server-grade 16 GB DDR4 module

This 16 GB DDR4 2133 registered DIMM is built for servers and workstations that require error-correcting memory. The 288-pin form factor fits standard DDR4 slots in compatible enterprise platforms. ECC and registered buffering protect data integrity in multi-socket systems. It targets administrators who need validated capacity for virtualisation or database workloads.

Steady throughput with registered buffering

The registered design places a register between the DRAM and the memory controller, reducing electrical load during sustained traffic. ECC corrects single-bit errors on the fly without halting the system. At DDR4 2133 the module delivers consistent bandwidth for long-running compute jobs. Rank organisation of 2Rx4 helps maintain signal quality across populated channels.

Qualified across 200000 configurations

Black Diamond Memory tests every module on actual server hardware before shipment. The 288-pin DDR4 interface ensures mechanical compatibility with a wide range of enterprise boards. Registered signalling allows higher total memory capacity per channel than unbuffered alternatives. Buyers who need non-ECC desktop memory or higher frequencies should look elsewhere.

Questions about this item

How much heat and power does a 16 GB 2Rx4 DDR4 2133 registered ECC module generate when running continuously?

Registered DDR4 2133 modules operate at the standard DDR4 voltage and the 2Rx4 organisation spreads the load across two ranks, keeping per-pin current low during sustained workloads.

What motherboard slot and memory controller features are required for this 288-pin DDR4 2133 registered ECC DIMM?

The module needs a server-class motherboard with 288-pin DDR4 slots that support registered (buffered) signalling and ECC; consumer boards that only accept unbuffered non-ECC DIMMs will not work.

Can this 2Rx4 DDR4 2133 registered ECC module share channels with other registered DDR4 DIMMs of different capacities?

Yes, provided every DIMM in the channel is DDR4 registered ECC; mixing 2Rx4 ranks with other registered ranks is supported by server memory controllers that follow the DDR4 2133 specification.
