NEMIX RAM 512GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit provides 512GB of DDR5 memory across eight 64GB registered DIMMs. It operates at 4800MHz with CL40 latency and 1.1V voltage. The modules feature ECC error correction and a 2Rx4 rank configuration for server stability.

Suited For SuperMicro SYS-531A-I Workstations

This memory is validated for the SuperMicro SuperWorkstation SYS-531A-I and compatible X13SRA-TF motherboards. It is not for systems requiring unbuffered UDIMM modules or non-ECC memory. Builders needing lower capacities or consumer desktop speeds should consider different kits.

DDR5 4800 Registered ECC With 2Rx4 Organisation

The decisive specification is the registered ECC RDIMM design with 2Rx4 organisation at DDR5 4800. This combination ensures compatibility with the target SuperMicro platform chipset and memory controller. Modules without registration or ECC will not function in this specific server environment.

Questions about this item

How do I choose between the 64 GB modules in this 512 GB kit?

The kit contains eight identical 64 GB modules. All slots must be populated with matching 2Rx4 registered DIMMs for the Supermicro SYS-531A-I to operate in eight-channel mode.

What does the 4800 MT/s rating deliver in the Supermicro SYS-531A-I?

Each module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V, providing the maximum supported memory bandwidth for the platform's eight-channel controller.

What does the 288-pin DDR5 RDIMM interface cap in practice?

The registered 288-pin DDR5 RDIMM form factor limits operation to the platform's supported DDR5 4800 speed and enforces ECC registered signalling across all eight channels.
