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.

Questions about this item

Will the 12 1Rx8 RDIMM modules populate every slot on my H13DSG-O-CPU without forcing a lower speed?

The kit provides twelve 16 GB 1Rx8 registered DIMMs that match the board's DDR5-4800, 1.1 V, CL40 specification, so the memory controller can run all channels at the rated data rate when populated per the manual.

How can I confirm the ECC registered DDR5 is active after installation?

Enter the BIOS or run a hardware inventory tool; it should report 192 GB of DDR5-4800 registered ECC memory with the correct rank and voltage, and the OS memory test will show ECC correction enabled.

Does the 192 GB kit include anything besides the twelve 288-pin RDIMMs?

The package contains only the twelve 16 GB DDR5-4800 ECC RDIMM modules; no heat spreaders, cables, or additional accessories are supplied.
