32GB DDR4 ECC RDIMM for Supermicro X10SDV

This 32GB DDR4 2133MHz registered ECC module is built for the Supermicro X10SDV motherboard series listed in the compatibility table. It targets server and workstation operators who need error-correcting memory to protect data integrity in multi-user or always-on environments. The CL15 latency and 1.2V operation match the platform's native specification.

Installation requires matching registered DIMM slots

The 288-pin RDIMM fits only registered DIMM slots; it will not work in unbuffered desktop boards and cannot be mixed with unbuffered modules. Verify that the motherboard BIOS recognises the 2Rx4 rank configuration before populating all channels. A common issue is inserting the module into a consumer board that physically accepts the notch but electrically rejects registered memory.

Sustained load stability with ECC correction

Under continuous workloads the ECC logic detects and corrects single-bit errors without halting the system, preventing silent data corruption during long compute or storage tasks. Registered buffering reduces electrical load on the memory controller, helping maintain signal quality when all slots are populated. The module runs at the rated 2133MHz without downclocking, delivering consistent throughput for the supported Supermicro platforms.

Domande su questo articolo

How can I confirm the 32GB DDR4 2133MHz ECC Registered RDIMM is operating correctly after installation?

Enter the system BIOS or UEFI and verify the installed capacity shows 32GB, speed reads 2133MHz (PC4-17000), and ECC status reports as enabled.

What is included with the OWC 2R1D42R432GB module and what must be purchased separately?

The box contains the single 32GB 288-pin DDR4 ECC Registered RDIMM; no additional cables, brackets or software are supplied, and no extra components are required for installation.

Which version of this memory should I choose for my Supermicro X10SDV motherboard?

Select the 32GB DDR4 2133MHz PC4-17000 CL15 1.2V 2Rx4 Registered ECC RDIMM (part 2R1D42R432GB) — it matches the Supermicro part numbers MEMDR432LHL01ER21, MEMDR432LSL01ER21 and MEMDR432LSV01ER21 for the listed X10SDV models.
