16GB DDR4 ECC RDIMM for Supermicro servers

This 16GB DDR4 2400 CL17 ECC registered DIMM is built for Supermicro X10 and X11 server and workstation boards. It targets administrators upgrading or repairing X10DRU-i+, X10DRW-i, X10DRW-iT, X11SDD-18C-F or X11SDD-8C-F systems. It is not for standard desktop computers or any platform that requires unbuffered memory.

Installation notes and common issues

The module uses a standard 288-pin DDR4 form factor and operates at 1.2V. Installation follows normal server DIMM procedure: power down, open the chassis, align the key notch, and press until the latches click. The most frequent error is mixing this registered ECC module with unbuffered DIMMs, which prevents the system from posting. Verify that every slot uses registered ECC before powering on.

Capacity headroom and limits

A single 16GB stick adds substantial memory for virtualization, databases, or large file caches on the listed Supermicro boards. Headroom scales with the number of populated slots up to the motherboard maximum. Workloads that exceed the total installed capacity will swap to storage, reducing responsiveness. This module alone does not address CPU, storage or network bottlenecks.

Questions about this item

How do I confirm the DDR4 2400 CL17 ECC RDIMM is running correctly after installation?

Enter the system BIOS or UEFI on the Supermicro X10DRU-i+, X10DRW-i, X10DRW-iT, X11SDD-18C-F or X11SDD-8C-F and verify the memory is detected at 2400 MHz with CL17 timings and ECC enabled.

What comes in the box and do I need anything else to install the 288-pin module?

The box contains the 16 GB OWC 2R4D42R816GB RDIMM only; no tools, cables or additional brackets are required for the 288-pin DIMM slots on the listed Supermicro boards.

Should I choose this 16 GB 2Rx8 registered module or a different capacity for my Supermicro motherboard?

This 16 GB 2Rx8 PC4-19200 registered ECC DIMM replaces Supermicro MEMDR416LCL06ER24, MEMDR416LHL03ER24 and MEMDR416LSV01ER24; select it when you need a single 16 GB registered module for the compatible X10 or X11 series boards.
