16GB DDR4 ECC RDIMM for servers

This 16GB DDR4 2133MHz module is built for servers and workstations that require error-correcting registered memory. It uses a 2Rx4 dual-rank layout with Micron chips and runs at the standard 1.20V. The 288-pin RDIMM form factor fits compatible enterprise platforms.

Upgrade from non-ECC or lower-capacity DIMMs

Replacing unbuffered or non-ECC memory with this registered ECC module adds data integrity protection for critical workloads. The jump is worth it when your motherboard and CPU support registered DIMMs and you need the 16GB density per slot. Systems limited to unbuffered memory cannot use this module.

Fits registered DDR4 channels.

This RDIMM installs directly into 288-pin DDR4 registered memory channels on qualified server boards. Each 16GB stick increases total capacity while leaving additional slots open for further expansion. Verify your platform’s qualified vendor list for the MEM-DR416L-CL01-ER21 part number before installation.

Questions about this item

Does the 288-pin RDIMM fit a standard DDR4 server DIMM slot?

Yes, the 288-pin RDIMM form factor matches the DDR4 registered DIMM slots used in compatible Supermicro and other server platforms.

What BIOS setting or slot order is required when installing this 2Rx4 registered module?

Install modules in the sequence recommended by the motherboard manual; registered DIMMs must populate the correct channels first and the BIOS must be set to run at 1.2 V for DDR4 2133 operation.

When should the 16 GB Micron chipset module be replaced or tested?

Run a memory diagnostic if the system shows corrected ECC errors, unexpected reboots, or fails to recognise the full 16 GB capacity during POST.
