Server-grade DDR4 module for registered ECC

The Black Diamond Memory BD16G2933MQR26 is a 16GB DDR4 SDRAM DIMM built for systems that require registered error-correcting memory. It operates at DDR4 2933 (PC4 23400) and uses a 288-pin interface with a 2Rx4 rank organisation. This module targets enterprise servers and workstations where data integrity and platform compatibility are mandatory.

Registered buffering steadies sustained throughput

Registered signalling places a register between the DRAM and the memory controller, reducing electrical load on the bus during continuous operation. ECC logic detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 2Rx4 organisation distributes accesses across two ranks, helping maintain bandwidth when multiple channels are populated under heavy multi-threaded workloads.

Validated across 200000 platform configurations

Black Diamond Memory reports validation across 200000 system configurations since the line was first listed in 2019. The 288-pin DDR4 form factor fits standard registered DIMM slots in qualified server boards. Builders must verify that their platform explicitly supports registered ECC DDR4 2933 modules, as unbuffered or non-ECC boards will not accept this memory.

Questions about this item

Does the 2Rx4 registered DDR4 2933 module add noticeable heat or power draw when the server runs all day?

As a 16 GB registered DDR4 2933 DIMM it draws standard DDR4 voltage and produces typical heat for a dual-rank server module; airflow in a normal chassis is sufficient.

What must the buyer already own for this 288-pin DDR4 2933 ECC registered DIMM to work?

A server or workstation motherboard with DDR4 RDIMM slots that support ECC and 2933 MT/s operation.

How does this 2Rx4 registered DDR4 2933 module behave alongside other DDR4 registered DIMMs the buyer may keep?

It will run at the lowest common speed and voltage supported by the platform; all installed DIMMs must be registered ECC for the system to operate correctly.
