Server memory upgrade

This OWC module provides 64GB of DDR4 ECC registered memory for compatible Supermicro M11SDV motherboards. It is intended for administrators extending the life of existing server or workstation platforms that require registered DIMMs.

288-pin registered DIMM

The stick uses a standard 288-pin DDR4 form factor with ECC and registered buffering. It cannot be mixed with unbuffered memory and will not function in standard desktop systems that lack registered DIMM support.

Low-voltage operation

Rated at 1.2V with CL19 latency at 2666MHz, the module runs within JEDEC specifications for reduced power draw. Backward compatibility with 2133MHz and 2400MHz systems allows deployment in mixed-speed configurations.

Domande su questo articolo

Does the DDR4-2666 ECC RDIMM run at 2666 MHz or drop to 2400 MHz on a 2400 MHz bus?

It operates at 2666 MHz on a 2666 MHz bus and will clock down to 2400 MHz or 2133 MHz if the platform runs at those lower speeds.

Will the 288-pin 64 GB registered module fit a Supermicro M11SDV motherboard with standard DIMM slots?

Yes, the 288-pin DDR4 RDIMM form factor matches the standard DDR4 DIMM sockets on the listed Supermicro M11SDV boards.

What is the correct order for populating the 2Rx4 ECC RDIMM in a four-slot Supermicro M11SDV board?

Install the module in the slot designated as Channel A DIMM 0 first, following the motherboard manual's population sequence for registered memory.
