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.
