512GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit provides 512GB of DDR5 4800 registered ECC memory across eight 64GB modules. It is built for SuperMicro servers and workstations that require registered DIMMs with error correction. The modules operate at 1.1V with CL40 latency and use a 288-pin 2Rx4 layout. This is a new, system-specific upgrade for compatible SuperMicro platforms.

Suits SuperMicro SSG-521E and X13SEDW-F owners

Designed for administrators expanding SuperMicro Storage SuperServer SSG-521E-E1CR24H, SSG-521E-E1CR24L or X13SEDW-F systems. Not for desktops, laptops or consumer motherboards that accept only unbuffered non-ECC memory. Buyers needing lower capacities, higher speeds or unregistered modules should look elsewhere.

Eight 64GB registered DIMMs

The kit delivers its full 512GB capacity through eight 64GB registered ECC RDIMMs. This module count and density decide whether the target server's memory slots and maximum supported capacity can accept the upgrade.

Questions about this item

Will the CL40 latency limit throughput on the SuperMicro SSG-521E-E1CR24H under sustained load?

CL40 is the rated CAS latency for these DDR5 4800 modules; sustained throughput will follow the JEDEC timing table for PC5-38400.

How much heat do the eight 64GB RDIMMs generate when running 24/7 at 1.1V?

The kit operates at 1.1V with no heat spreaders; power draw stays within standard DDR5 4800 registered DIMM limits for server chassis airflow.

Which SuperMicro motherboard must I already have for this 8x64GB kit to work?

The memory is validated for SuperMicro Storage SuperServer SSG-521E-E1CR24H, SSG-521E-E1CR24L and X13SEDW-F platforms.
