  • 288-pin RDIMM form factor fits the exact slots required by this motherboard

Exact-match 128 GB DDR5-4800 kit

This 128 GB kit contains eight 16 GB DDR5 RDIMM modules rated at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for the Supermicro H13DSG-O-CPU motherboard and delivers registered ECC memory for enterprise workloads.

Installation fit and population rules

The 288-pin RDIMM form factor matches the board's DIMM slots; UDIMM or SODIMM modules will not fit. Consult the motherboard manual for the approved population order and supported capacities before installing all eight modules.

Registered ECC limits at DDR5-4800

Registered buffering lets every slot run fully populated at the rated speed while ECC corrects single-bit errors on the fly. The DDR5-4800 standard caps transfer rate at 4800 MT/s, so bandwidth cannot exceed PC5-38400 regardless of processor capability.

Questions about this item

How can I verify the 128GB kit is running at DDR5 4800 with CL40 after installation?

Check the BIOS or UEFI memory information screen; it should show 4800 MT/s speed, CL40 latency, 1.10 V voltage, and all eight 16 GB modules recognised as registered ECC RDIMMs.

What comes in the box and is anything else required for the Supermicro H13DSG-O-CPU?

The kit includes eight 16 GB DDR5 4800 CL40 1.1 V 288-pin registered ECC RDIMMs; no additional parts are needed if the motherboard DIMM slots are free and the manual population order is followed.

Should I choose this 128 GB 8x16 GB kit or a different capacity for the H13DSG-O-CPU?

Select this 128 GB kit when you need eight 16 GB 1Rx8 registered ECC modules at DDR5 4800 CL40 1.1 V; choose another capacity only if your board manual lists a different supported total or population rule.
