NEMIX RAM
A 768GB kit of six 128GB DDR5 4800 CL40 ECC registered DIMMs for SuperMicro servers
This 768GB kit contains six 128GB DDR5 4800 ECC RDIMM modules built for SuperMicro FatTwin and SuperServer platforms. Registered buffering and on-die ECC protect data integrity in multi-socket workloads. The kit is validated for SYS-F521E3-RTB, SYS-F511E2-RT and X13SEFR-A systems.
IT teams expanding memory density in compatible SuperMicro 13th-generation servers for virtualization, database or HPC clusters. Buyers needing consumer DIMM form factors, non-ECC operation or speeds above 4800 MT/s should look at other product lines.
The 4Rx4 rank organisation across six 288-pin RDIMMs delivers the stated 768GB capacity at 1.1V; verify that your motherboard firmware supports this rank population before ordering.
