Exact-fit DDR5 RDIMM kit

This 1.5 TB kit contains twelve 128 GB DDR5 registered DIMMs rated at 4800 MT/s with CL40 timing and 1.10 V operation. It is built for the Supermicro H13DSG-O-CPU motherboard and will only work in systems that accept 288-pin DDR5 RDIMM modules with ECC.

Upgrade from partial or lower-capacity population

The kit replaces any smaller or mixed-capacity DDR5 RDIMM configuration that leaves memory channels unfilled. The jump is worth it when the workload needs the full 1.5 TB address space and the board’s population rules allow all twelve slots to be occupied with 2Rx4 registered modules.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller so every slot remains stable at the rated 4800 MT/s speed during continuous operation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during long-running compute or database tasks.

Questions about this item

What motherboard and form factor do these 12 288-pin DDR5 RDIMMs require?

They are built for the Supermicro H13DSG-O-CPU motherboard and use the 288-pin RDIMM form factor; UDIMM or SODIMM modules will not fit.

What population order should I follow when installing all 12 modules?

Consult the Supermicro H13DSG-O-CPU manual for the approved DIMM population sequence; installing in the wrong slots can prevent the system from recognising the full 1.5 TB capacity.

Do these registered ECC modules need any firmware updates or battery replacements over time?

No firmware updates or battery replacements are required; the registered ECC design provides error correction for the module's lifetime.
