NEMIX RAM DDR5 4800 ECC RDIMM 192GB (12×16GB) CL40 1.1V Supermicro H13DSG-O-CPU memory upgrade

Supermicro H13DSG-O-CPU upgrade kit

This 192GB kit contains twelve 16GB DDR5 RDIMMs built to the exact specifications required by the Supermicro H13DSG-O-CPU motherboard. Each module is a 288-pin registered ECC DIMM operating at 1.1V with CL40 latency. The kit delivers the precise rank, voltage, and timing the server memory controller expects for full capacity recognition.

192GB capacity with registered ECC headroom

Twelve 1Rx8 modules provide 192GB of registered ECC memory, allowing every slot to run fully populated while the registered architecture offloads the memory controller. ECC corrects single-bit errors on the fly to prevent silent data corruption. The DDR5 4800 speed rating sets the maximum data rate this kit guarantees.

DDR5 4800 interface limits

The PC5-38400 standard defines the peak transfer rate at 4800 MT/s, so workloads demanding higher bandwidth will hit this ceiling. Registered DIMMs add a clock cycle of latency versus unbuffered modules, which affects latency-sensitive tasks. The 288-pin form factor fits only DDR5 RDIMM slots, not UDIMM or SODIMM sockets.
