64GB DDR5 ECC RDIMM for servers

This 64GB DDR5 5600 registered DIMM delivers error-correcting memory capacity for enterprise workloads. The module operates at 1.1V with CL46 latency and uses a 2Rx4 organisation built from major OEM DRAM chips. It fits 288-pin DDR5 slots in compatible servers and workstations.

Registered design and ECC change system behaviour

The registered buffer reduces electrical load on the memory controller, allowing higher module counts per channel. On-die ECC corrects single-bit errors and detects multi-bit faults, protecting data integrity in mission-critical applications. No heat spreader is included, so airflow in the chassis must be sufficient for bare modules.

Suits IT teams upgrading OEM servers and NAS devices

Buyers needing registered ECC DDR5 at 5600 MT/s for validated platforms will find this module matches the specification. Systems that require unbuffered UDIMMs, lower voltages, heat-spreader cooling or speeds beyond 5600 MT/s should look at other memory types.

Questions about this item

Will the ECC RDIMM module require any firmware updates or chipset replacements during its service life?

The registered DDR5 module has no user-serviceable firmware or replaceable chipset; it operates as a passive component once installed in a compatible server board.

What thermal limit is reached first when the 2Rx4 module runs at 5600 MT/s continuously?

The 1.10 V operating voltage and lack of a heat spreader mean the DRAM junction temperature will hit its rated maximum before the PCB or register components do.

How much power does the 64 GB stick draw and how loud is it during 24-hour operation?

At 1.1 V the module consumes only a few watts and produces no audible noise because it has no fan or moving parts.
