Black Diamond Memory BD8GX22133MQR26 16GB (2 x 8GB) DDR4 2133 ECC Registered server RAM

Server ECC Registered DDR4 Kit

This 16 GB kit contains two 8 GB DDR4 2133 registered DIMMs with ECC. It is built for servers and workstations that require error correction and signal buffering. The modules use a 288-pin form factor and a 2Rx4 organisation. They are not suitable for standard desktop boards that only accept unbuffered memory.

Verify Registered DIMM Support

Check that your motherboard and CPU explicitly support registered ECC DDR4 before ordering. Consumer chipsets and many entry-level workstation boards will not post with these modules. Confirm the maximum supported speed and total capacity per channel in your system documentation. The kit operates at PC4 17000 and will downclock if the platform requires a lower rate.

Steady Enterprise Workloads

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors that can accumulate under sustained write cycles. The 2Rx4 density helps maintain stability when all slots are populated for long-running database or virtualisation tasks. Heat output remains consistent because the modules run at standard DDR4 2133 voltage.
