NEMIX RAM
Eight-module kit provides 256 GB of DDR5 4800 ECC registered RDIMM memory for Supermicro workstations
This 256 GB DDR5 kit contains eight 32 GB registered ECC RDIMMs built for the SuperMicro SuperWorkstation SYS-531A-I. It targets IT professionals who need maximum memory density for virtualisation, database or compute workloads on that specific platform.
Each module uses a 288-pin DDR5 RDIMM form factor with a 1Rx4 organisation and runs at 1.10 V. The registered buffer and on-die ECC protect data integrity, while the lack of heat spreaders keeps the profile low for dense server chassis.
The package delivers the full 256 GB as a matched set of eight modules, eliminating the need to source individual sticks. NEMIX RAM validates every kit under load before shipment, so the memory arrives ready for immediate installation in the qualified SuperMicro system.

The DDR5 4800 specification delivers up to 4800 MT/s, which corresponds to a PC5-38400 bandwidth rating for each 32 GB module.
The kit uses standard 288-pin DDR5 RDIMM modules; the board needs DDR5 RDIMM slots with the matching key notch.
Insert each module into the correct channel slots following the motherboard manual, and populate all eight slots identically to keep 1Rx4 ranking consistent.
