Server-grade ECC RDIMM for Supermicro X11

This 128GB DDR4 2933MHz CL21 registered DIMM delivers ECC error correction for Supermicro X11DPi-NT, X11DPL-i, X11DPS-RE, X11DPT-B and X11DPT-BH motherboards. It operates at 1.2V with a 4Rx4 organisation and no heat spreader. The module targets servers, workstations and NAS systems that require registered memory.

Verify motherboard model and memory population rules

Confirm your board is one of the five listed X11 models before ordering. Registered ECC RDIMMs will not work in standard desktop platforms and cannot be mixed with unbuffered modules. Check the system manual for maximum capacity per slot, supported ranks per channel and required DIMM population order.

Fits 288-pin DDR4 slots; runs at lower JEDEC speeds

The 288-pin form factor seats directly in the board's DDR4 slots. Backward compatibility allows operation at 2133MHz, 2400MHz or 2666MHz if the platform demands it. Using registered ECC memory frees the CPU from single-bit error handling and supports higher densities per channel than unbuffered alternatives.

Questions sur cet article

Does the 128GB module ship with any cables or brackets, or is it just the DIMM?

Only the 288-pin DDR4 ECC Registered RDIMM is included; no cables, brackets or additional hardware are supplied.

Should I pick the 2933MHz CL21 version or a slower 2666MHz module for my X11DPL-i?

The 2933MHz CL21 module runs at 2933MHz on supported boards and will also operate at 2666MHz, 2400MHz or 2133MHz if the platform requires it.

What does the 2933MHz rating actually deliver once the DIMM is installed in a Supermicro X11DPT-B?

On that motherboard the module runs at 2933MHz (PC4-23400) with CL21 latency and 1.2V, providing 128GB of registered ECC capacity per DIMM.
