Exact-match DDR5 server kit

This 288GB kit contains six 48GB DDR5 4800 RDIMM modules built for the Supermicro H13DSG-O-CPU-D motherboard. The registered ECC design matches the board's required 288-pin form factor and 1.1V operating voltage so the memory controller recognises full capacity at rated speed.

Registered ECC architecture

Registered buffering offloads the memory controller allowing every slot to run fully populated while ECC corrects single-bit errors on the fly. This combination prevents silent data corruption and unplanned reboots in production workloads.

CL40 latency at DDR5 4800

The modules operate at CL40 CAS latency with a 2Rx8 rank structure. This timing is the single specification that determines whether the kit runs at its rated DDR5 4800 speed on the target platform.

Questions about this item

Will the registered ECC RDIMM modules require any periodic maintenance or replacement under normal server operation?

Registered ECC RDIMMs have no moving parts and no scheduled maintenance; ECC corrects single-bit errors on the fly, and the modules are only replaced if a hardware fault is detected.

What limit appears first when the six 48 GB DIMMs run at DDR5-4800 CL40 continuously?

The memory controller’s maximum supported capacity and population rules for the Supermicro H13DSG-O-CPU-D board determine the practical limit, not the DIMM rating itself.

How much heat and power do the 1.1 V DDR5 modules generate when fully populated all day?

At 1.1 V the kit draws low voltage per module, and with no heat spreaders the DIMMs rely on chassis airflow to stay within thermal limits during sustained loads.
