A-Tech 16 GB DDR4 2133 ECC RDIMM

This is a 16 GB DDR4 2133 MHz ECC registered DIMM built with Samsung chips and certified for Supermicro servers. It runs at 1.2 V with CL15 latency and a 2Rx4 rank configuration on a 288-pin form factor.

Suited for Supermicro DDR4 2133 slots only

This module fits systems that specifically require DDR4 2133 ECC RDIMM memory with 2Rx4 organisation. It will not work in boards that need unbuffered UDIMM, load-reduced LRDIMM, a different speed grade or a non-ECC configuration.

Deciding spec: 2Rx4 ECC RDIMM at DDR4 2133

The registered 2Rx4 ECC design at 2133 MHz is the single specification that determines compatibility. Verify that your platform supports this exact rank, buffer type and speed before ordering.

Questions about this item

How can I verify the module is running at DDR4 2133 with CL15 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report 2133 MT/s, 1.20 V and CAS latency 15 for this 16 GB RDIMM.

What ships with the MEM-DR416L-SL01-ER21 and do I need extra parts?

The box contains one 16 GB Samsung M393A2G40DB0-CPB RDIMM; no cables, brackets or additional components are required for a compatible 288-pin server slot.

When should I choose this 16 GB 2Rx4 registered ECC stick over other capacities?

Select this module when your Supermicro system calls for a single 16 GB dual-rank DDR4 2133 registered ECC DIMM to fill a specific slot or reach a desired total.
