NEMIX RAM
A 128GB DDR5 4800 registered ECC RDIMM module built for SuperMicro X13 servers
This 128GB DDR5 4800 registered DIMM delivers ECC error correction for SuperMicro server platforms. It operates at 1.1V with CL40 latency and a 4Rx4 organisation. The module uses major OEM DRAM chips and fits 288-pin DDR5 slots.
IT teams upgrading SuperMicro SYS-211E-FRN2T, SYS-211E-FRDN2T or X13SEM series SuperServers with validated ECC memory. Builders needing non-ECC UDIMMs, lower capacities, different speeds or consumer motherboard compatibility should choose another module.
The single spec that decides fit is the 128GB 4Rx4 registered ECC DDR5 4800 configuration. Only systems qualified for this exact density, rank structure and registered signalling will accept the module.

The module runs at 1.1V with CL40 timing; consult the SYS-211E-FRN2T manual for the minimum BIOS version that supports 4800 MT/s DDR5 RDIMMs.
Yes, matching speed, voltage and registered ECC design allows mixed population; follow the motherboard population rules for 4Rx4 modules.
Check the BIOS memory information screen for 4800 MT/s, 1.10V, CL40 and ECC enabled, then run a memory diagnostic to verify stability.
