Certified Supermicro Server Memory

This 16GB DDR4 RDIMM carries Supermicro certification and uses Micron chips to deliver registered ECC operation for compatible server platforms. The single-rank 1Rx4 design runs at 2666MHz with CL19 latency at the standard 1.20V DDR4 voltage. It targets administrators who need validated modules for Supermicro-qualified systems.

Registered ECC with 1Rx4 Organisation

The module implements registered ECC DDR4 in a 288-pin RDIMM form factor, providing error correction and signal buffering required by many multi-socket server boards. Its 1Rx4 single-rank layout using x4 DRAM devices determines electrical loading per channel, so the platform's memory controller must support this rank geometry and registered signalling.

Fits 288-Pin DDR4 RDIMM Slots

Installation requires motherboard slots wired for DDR4 registered DIMMs with ECC enabled in the firmware. The stick occupies one 288-pin slot and draws 1.20V, leaving remaining slots available for identical modules to populate channels per the board's population rules. Systems needing unbuffered UDIMMs or non-ECC memory cannot use this part.

Questions about this item

What does the 2666MHz speed mean once this module is installed in a server?

The module runs at 2666 MT/s, delivering up to 21300 MB/s of peak bandwidth per stick; actual throughput depends on the memory controller and how many channels are populated.

How does the registered ECC interface affect what the system can do?

Registered ECC adds a register between the DRAM and the memory controller, reducing electrical load so more modules can be used per channel while correcting single-bit errors in flight.

What physical slot and keying does this 288-pin RDIMM require?

It fits a standard DDR4 288-pin RDIMM socket with the registered DIMM key notch; the module will not seat in UDIMM or SO-DIMM slots.
