Server-grade DDR5 ECC registered kit

This kit supplies 512 GB of DDR5 memory across eight 64 GB registered DIMMs. It is built for workstations, NAS systems, servers and network switches that require ECC registered modules. Standard desktop platforms cannot use this memory.

Registered design with on-die ECC

Registered buffering reduces electrical load on the memory controller, allowing the full eight-module population. On-die ECC corrects single-bit errors inside each DRAM, improving data integrity for long-running workloads. The modules operate at 1.1 V and carry no heat spreaders.

512 GB total capacity at DDR5 5600 CL46

The 512 GB pool handles large virtualisation clusters, in-memory databases and heavy render queues with headroom to spare. Performance scales with the platform’s dual-channel architecture. Workloads that exceed 512 GB or need load-reduced DIMMs will require a different memory type.

商品問答

Will the eight 64 GB modules need any firmware updates or battery-backed components replaced during their service life?

The modules are standard JEDEC DDR5 ECC Registered RDIMMs with no onboard firmware or battery-backed parts, so no firmware updates or battery replacements are required.

What is the first limit reached when all eight sticks run at DDR5 5600 CL46 continuously?

The registered buffer and on-die ECC add latency, so the memory controller's maximum supported rank count per channel is typically reached before bandwidth or thermal limits.

How much heat and noise do the bare modules produce in a fully populated server running all day?

With no heat spreaders and a 1.1 V operating voltage, each 64 GB stick runs cool and silent; total system noise and heat depend on the chassis fans and airflow, not the modules themselves.
