16GB DDR4 2133MHz ECC Registered RDIMM

This 16GB DDR4 2133MHz module is built for servers and workstations that require error-correcting registered memory. It uses a 2Rx4 dual-rank layout and runs at the standard 1.20V voltage. The stick carries Supermicro certification for the MEM-DR416L-HL01-ER21 part number.

Sustained load behaviour with CL15 latency

At CL15 latency the module delivers consistent throughput during extended workloads rather than only in short bursts. Registered buffering reduces electrical load on the memory controller, helping stability when all slots are populated. ECC circuitry corrects single-bit errors on the fly to prevent data corruption over long runs.

Check your platform before ordering

Verify that your motherboard supports DDR4 RDIMM modules at 2133MHz with ECC registered operation. The 288-pin form factor fits standard DDR4 server slots, but some consumer boards cannot use registered memory. Confirm the maximum supported capacity per slot and total population rules in your system documentation.

Questions about this item

How much power does the 1.20V DDR4 2133MHz module draw when running continuously in a server?

At the standard 1.20V DDR4 voltage the 16GB RDIMM operates within normal server memory power envelopes; exact sustained draw depends on workload and platform but no elevated voltage is required.

What motherboard feature must my system already have to use this ECC Registered 288-pin RDIMM?

The board must provide DDR4 RDIMM slots that support ECC Registered memory and accept 2Rx4 modules at 2133MHz.

Will this CL15 2Rx4 module work alongside older DDR4 2133MHz sticks I already own?

It can run with other DDR4 2133MHz ECC Registered DIMMs, though mixing ranks or CAS latencies may force the system to the slowest common timing.
