Server ECC RDIMM for Supermicro X11

This 32GB DDR4 2933MHz registered DIMM targets server and workstation builders who need error-correcting memory for Supermicro X11DAC, X11DAi-N, X11DDW-L, X11DDW-NT or X11DGO-T motherboards. It delivers 2Rx4 organisation at CL21 latency and 1.2V operation. The module is not compatible with standard desktop platforms or unbuffered memory configurations.

Fits X11 DDR4 slots alongside identical modules

The 288-pin RDIMM installs directly into the listed Supermicro boards and runs at 2933MHz with backward compatibility to 2133MHz, 2400MHz and 2666MHz speeds. Registered buffering reduces electrical load on the memory controller, freeing headroom for larger capacity configurations. Mixing with unbuffered DIMMs is not supported.

Sustained ECC operation at JEDEC voltage

Under continuous load the module maintains 1.2V and CL21 timings while ECC corrects single-bit errors in real time. Registered signalling stabilises the command bus across fully populated channels. No heat spreader is fitted, so airflow across the PCB manages thermal performance during extended workloads.

Preguntas sobre este artículo

How much power does the 1.2V registered DDR4 module draw under sustained load?

The module operates at 1.2V with CL21 timings at 2933MHz; registered buffering adds slight overhead but keeps power draw within standard DDR4 RDIMM limits for server workloads.

Will the 288-pin ECC RDIMM run hot or loud during 24/7 operation?

No heat spreader is fitted; the bare PCB relies on chassis airflow. At 1.2V and CL21 the module stays cool in typical server airflow and adds no audible noise.

Which motherboards must I already own for this 32GB kit to work?

Compatible Supermicro boards are X11DAC, X11DAi-N, X11DDW-L, X11DDW-NT and X11DGO-T; the module also replaces Supermicro part numbers MEM-DR432LC-ER29, MEMDR432LCL01ER29, MEMDR432LCL02ER29, MEMDR432LCL03ER29, MEMDR432LHL01ER29, MEMDR432LHL02ER29, MEMDR432LSL01ER29 and MEMDR432LSL03ER29.
