OWC 16GB DDR4 2400 ECC RDIMM

This is a 16GB DDR4 2400MHz PC4-19200 CL17 registered ECC DIMM operating at 1.2V. It uses a 288-pin 2Rx8 form factor without a heat spreader. The module is built for server and workstation platforms that require registered memory with error correction.

Suits Supermicro A2SDi and A2SDV boards

Designed for Supermicro motherboards A2SDi-12C-HLN4F, A2SDi-H-TF, A2SDV-4C-LN10PF, A2SDi-4C-HLN4F and A2SDi-8C+-HLN4F. It replaces Supermicro part numbers MEMDR416LCL06ER24, MEMDR416LHL03ER24 and MEMDR416LSV01ER24. Not for standard desktop computers and cannot be mixed with unbuffered memory.

16GB capacity for server workloads

A single 16GB module adds substantial memory headroom for virtualization, NAS services and multi-user applications. Registered ECC operation maintains data integrity under sustained load. Capacity scales with available DIMM slots on the target motherboard.

Questions about this item

Does this 288-pin DDR4 2400 RDIMM require a Supermicro A2SDi motherboard to operate?

Yes, the module is validated for Supermicro A2SDi-12C-HLN4F, A2SDi-H-TF, A2SDV-4C-LN10PF, A2SDi-4C-HLN4F and A2SDi-8C+-HLN4F boards.

Can I mix this ECC registered 2Rx8 stick with unbuffered DDR4 already installed in my server?

No, registered memory cannot be mixed with unbuffered memory; all slots must use registered ECC modules.

How do I confirm the 16 GB module is running at PC4-19200 CL17 after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify speed 2400 MT/s, CAS 17 and ECC registered status.
