32GB DDR4 ECC RDIMM for Supermicro X10SDV

This 32GB DDR4 2133MHz CL15 registered DIMM is built for Supermicro X10SDV motherboards including the 7TP8F, 8C-TLN4F+ and TP8F models. It operates at 1.2V with ECC error correction and a 2Rx4 rank layout. The module replaces Supermicro part numbers MEMDR432LHL01ER21, MEMDR432LSL01ER21 and MEMDR432LSV01ER21.

Not for desktops or unbuffered builds

This registered ECC memory will not work in standard desktop computers or consumer laptops. It cannot be mixed with unbuffered modules in the same system. Buyers who need non-ECC UDIMMs for a desktop platform should look at a different product line.

Steady throughput under sustained server loads

The JEDEC-compliant DDR4 2133MHz CL15 timing delivers consistent bandwidth during long compute runs, virtualization workloads or NAS duties. Registered buffering reduces electrical load on the memory controller, helping stability when all DIMM slots are populated over extended periods.

Questions about this item

Which motherboard models must I already own for this OWC 32GB DDR4 2133MHz CL15 ECC Registered RDIMM to work?

This module is validated for Supermicro motherboards X10SDV-7TP8F, X10SDV-8C-TLN4F+ and X10SDV-TP8F. It replaces Supermicro part numbers MEMDR432LHL01ER21, MEMDR432LSL01ER21 and MEMDR432LSV01ER21.

Can I keep my existing unbuffered DDR4 DIMMs and add this 2Rx4 registered ECC module alongside them?

No. Registered ECC memory cannot be mixed with unbuffered DIMMs; the system requires all installed modules to be registered ECC of matching specification.

How do I confirm the 32GB module is running at 2133MHz CL15 with ECC active after installation?

Enter the BIOS or use a hardware information utility; it should report 32GB capacity, DDR4-2133 speed, CL15 latency, 1.2V voltage and ECC registered operation.
