Server ECC registered memory

This 32 GB DDR4 module runs at 2133 MHz with CL15 timing and 1.2 V operation. It is built for Supermicro X10SDV server and workstation boards. The registered design adds a buffer that stabilises heavy multi-module loads. It cannot be used in standard desktop computers.

DDR4 2133 registered limits

Registered ECC RDIMMs operate at the rated 2133 MHz speed and require a platform that supports registered signalling. Mixing with unbuffered memory is not supported and will prevent boot. The module is validated for the listed Supermicro motherboards only.

288-pin RDIMM build and use

The module uses a standard 288-pin DDR4 connector without a heat spreader, fitting server DIMM slots directly. ECC and registered operation provide error correction and signal integrity for continuous workloads. It replaces Supermicro part numbers MEMDR432LHL01ER21, MEMDR432LSL01ER21 and MEMDR432LSV01ER21.

Questions about this item

Should I pick the 32 GB 2133 MHz registered ECC module or a different capacity for my Supermicro X10SDV board?

This module provides 32 GB per DIMM at DDR4 2133 CL15 1.2 V in a 288-pin registered ECC form factor. Choose it when your X10SDV motherboard requires registered ECC memory and you need a single 32 GB stick.

What does the PC4-17000 2133 MHz rating deliver once the DIMM is installed in a server?

The PC4-17000 label means a peak transfer rate of 17000 MB/s at 2133 MHz with CL15 latency, giving the bandwidth and error correction the board expects for stable workloads.

How does the DDR4 288-pin registered ECC interface limit what I can mix with this module?

The 288-pin DDR4 registered ECC interface only works with other registered ECC DIMMs; it cannot be mixed with unbuffered or non-ECC memory and will not fit desktop platforms.
