48GB DDR5 RDIMM for Supermicro H13DSG-O-CPU-D

This registered ECC module is built as an exact-match upgrade for the Supermicro H13DSG-O-CPU-D motherboard. It delivers 48GB of DDR5-4800 memory in a single 288-pin RDIMM so administrators can expand server capacity without mixing ranks or voltages.

Capacity and registered headroom

The 2Rx8 organisation and registered buffer let the memory controller drive every slot at the rated 4800 MT/s while ECC corrects single-bit errors on the fly. Systems that need more than one module per channel benefit from the reduced electrical load, but boards limited to single-rank DIMMs or UDIMM-only slots cannot use this part.

CL40 1.1V DDR5-4800 spec match

The module runs at CL40 latency and 1.1V, the exact timing and voltage the H13DSG-O-CPU-D memory controller expects for stable operation at PC5-38400 speed. Deviating from these values will prevent the server from posting at the rated frequency.
