NEMIX RAM DDR5 512GB 4x128GB 4800MHz CL40 ECC RDIMM Supermicro H14DSG-O-CPU

Exact DDR5-4800 RDIMM kit for Supermicro

This 512 GB kit contains four 128 GB registered ECC modules built to the DDR5-4800 PC5-38400 standard. The 2Rx4 organization, 1.10 V operating voltage and CL40 latency match the memory controller expectations of the Supermicro H14DSG-O-CPU motherboard so the full capacity is recognised at rated speed.

DDR5-4800 bandwidth ceiling limits sustained

Each module runs at 4800 MT/s with CL40 timing, so peak bandwidth is bounded by the DDR5-4800 interface. Registered buffering allows all four slots to stay populated without signal degradation, but the bus frequency itself cannot exceed the JEDEC base rate. Workloads that scale beyond this bandwidth will see no further gain from this kit.

512 GB total capacity suits large in-memory

Four 128 GB RDIMMs provide 512 GB of ECC-protected memory, enough for sizeable virtualization clusters, database buffers or HPC datasets. The 2Rx4 rank structure fills every DIMM slot on the board, leaving no free sockets for further expansion. Systems needing more memory must move to a platform with additional channels or higher-density modules.
