  • Validated for Supermicro X11DPi-NT, X11DPL-i, X11DPS-RE, X11DPT-B, X11DPT-BH
  • Backward compatible with 2133MHz, 2400MHz and 2666MHz systems

Server ECC RDIMM Upgrade

This 16GB DDR4 2933MHz ECC Registered RDIMM is built for Supermicro X11DPi-NT, X11DPL-i, X11DPS-RE, X11DPT-B and X11DPT-BH motherboards. It targets administrators expanding workstation, server or NAS memory capacity with validated modules. Buyers needing unbuffered desktop memory cannot use this product.

Registered DIMM Architecture

The registered design places a buffer between the memory controller and DRAM chips, reducing electrical load on the motherboard. This allows higher total capacities across populated slots but requires a platform that supports registered ECC memory. It cannot be mixed with unbuffered modules in the same system.

16GB Dual-Rank Headroom

A single 2Rx8 module delivers 16GB at CL21 1.2V with backward compatibility at 2133, 2400 and 2666MHz. It handles typical virtualisation and file-service workloads; larger datasets or heavy database caching will require additional modules to scale further.

Questions sur cet article

Does the 2Rx8 registered layout limit the number of modules I can install per channel on a Supermicro X11DPi-NT?

The module is a 2Rx8 registered DIMM; maximum modules per channel depends on the motherboard's memory-controller specification, not on the stick itself.

How much heat does the 1.2 V DDR4 2933 MHz registered ECC module produce under continuous server load?

Running at 1.2 V with no heat spreader, it draws standard DDR4 registered power; actual thermals depend on case airflow and DIMM density.

Which Supermicro motherboards must I already own for this 288-pin ECC RDIMM to work?

Qualified boards are X11DPi-NT, X11DPL-i, X11DPS-RE, X11DPT-B and X11DPT-BH; it will not work in standard desktop systems.
