Server ECC RDIMM for Supermicro Replacement

This OWC module is a 16 GB DDR4 3200 MHz registered DIMM with ECC and a 2Rx8 organisation. It matches the Supermicro part numbers MEM-DR416L-HL01-ER32, MEM-DR416L-HL02-ER32, MEM-DR416L-SL02-ER32 and MEM-DR416LD-ER32. The stick runs at 1.2 V with a CL22 latency and uses a standard 288-pin interface.

Suited for registered-memory platforms only

It fits workstations and servers that require ECC registered DDR4 memory. Systems that accept only unbuffered non-ECC modules cannot use this DIMM. Builders needing a different capacity or a lower voltage should look at other parts.

Registered ECC with 2Rx8 organisation

The registered buffer and on-die ECC are the decisive traits for compatibility. If the motherboard demands registered ECC DDR4 in a 2Rx8 configuration, this module meets that requirement.

Questions about this item

How can I verify the OWC 3R2D42R816GB module is running at 3200 MHz with CL22 after installation?

Enter the server BIOS or UEFI and confirm the memory frequency shows 3200 MT/s and CAS latency 22; the module will also report 1.2 V and ECC registered status in the system firmware.

What comes in the box with the OWC 16 GB DDR4 3200 ECC RDIMM and do I need anything else?

The package contains the single 288-pin RDIMM; no cables, brackets or additional parts are included and no separate purchase is required for installation.

Which capacity and rank should I choose if my Supermicro system lists MEM-DR416L-HL01-ER32 as the original part?

Select the 16 GB 2Rx8 version — it matches the Supermicro part number exactly and provides the same density and rank configuration.
