OWC 64GB DDR5 5600 ECC RDIMM

This OWC memory module delivers 64GB of DDR5 5600 capacity in a single 288-pin ECC Registered DIMM. It is validated for Supermicro X13DEI-T, X13DEM, X13DET-B, X13DGU and X13DSF-A motherboards. The module targets servers and workstations that require registered ECC memory for data integrity. It will not function in standard desktop platforms or alongside unbuffered or load-reduced DIMMs.

Thermals noise and power

Operating at the JEDEC-standard 1.1V, the module draws minimal power for its density and speed rating. No heat spreader is fitted, so airflow across the PCB manages thermals in typical server chassis. The registered buffer reduces electrical loading on the memory controller, contributing to stable operation under sustained workloads. Silent solid-state construction adds no acoustic noise to the system.

Build integration and constraints

The 2Rx4 dual-rank organisation maximises capacity per slot, freeing additional DIMM positions for future expansion. Installation requires a 288-pin DDR5 RDIMM slot with registered ECC support on the listed Supermicro platforms. Mixing with unbuffered or load-reduced modules is not supported. The single-module kit allows precise population to match channel requirements without purchasing unnecessary pairs.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in my Supermicro X13DEI-T, and what step do people often miss?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then enable ECC in the BIOS — skipping the BIOS step leaves error correction inactive.

What maintenance or replacement will this 64GB 2Rx4 ECC registered module need over its service life?

No scheduled maintenance is required; the module either continues operating or develops uncorrectable errors that the OS logs, at which point the single 64GB DIMM is replaced as a unit.

What limit appears first when this CL46 1.1V DDR5 5600 RDIMM runs sustained workloads on a Supermicro X13DGU?

The CAS latency of 46 cycles at 5600 MT/s sets the baseline response time; under continuous load the memory controller hits that timing ceiling before thermal or voltage limits become a factor.
