NEMIX RAM
Eight 64 GB DDR5 4800 CL40 ECC RDIMM modules deliver 512 GB of registered server memory for SuperMicro SuperWorkstation SYS-531A-I
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.
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.
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.

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.
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.
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.
