16GB DDR4 ECC Registered Server Memory

This 16GB DDR4 module is built for servers and workstations that require error-correcting registered memory. It suits administrators upgrading Supermicro platforms or similar enterprise systems needing 2133MHz RDIMM capacity.

Straightforward 288-pin RDIMM installation

The module seats in a standard DDR4 RDIMM slot like any registered DIMM. Most issues arise when mixing registered and unbuffered memory or populating slots in an order the motherboard manual does not support.

2Rx4 dual-rank organisation

The 2Rx4 layout determines how the memory controller addresses the chips and affects maximum population per channel. Verify that your platform supports dual-rank registered modules at this density before purchasing.

Questions about this item

How can I confirm the 16GB DDR4 2133MHz ECC Registered module is running at CL15 and 1.20V after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 2133 MT/s, CAS latency 15, 1.20 V and ECC Registered status for the installed DIMM.

What is included in the box and do I need any extra parts to install this 288-pin RDIMM?

The box contains the single 16GB 2Rx4 RDIMM only; no cables, brackets or additional hardware are required — just an available DDR4 288-pin registered DIMM slot on a compatible motherboard.

Which capacity and rank version should I choose if my server manual lists MEM-DR416L-HL02-ER21 as a supported part?

Select this exact 16GB 2Rx4 module (MPN HMA42GR7AFR4N-TF) because it matches the Supermicro certified part number and the dual-rank x4 organisation your manual specifies.
