Exact-match DDR5 RDIMM kit

This 256GB kit contains two 128GB DDR5 5600 PC5-44800 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14DSG-O-CPU memory controller expects. The 2Rx4 organisation and 1.1V operation allow every populated slot to run at the rated 5600 speed without down-clocking.

Replaces mismatched or lower-capacity DIMMs

Upgrading from smaller RDIMMs or mixed-rank modules removes the population limits that force empty slots or reduced frequencies. The jump is worth it when the workload needs the full 256GB address space and the board’s qualified-vendor list calls for CL46 2Rx4 registered parts.

256GB registered ECC headroom

The dual-rank registered architecture offloads the memory controller so all channels stay fully populated at 5600 MT/s while ECC corrects single-bit errors on the fly. Capacity runs out when the application dataset exceeds 256GB or when the platform’s maximum supported memory per socket is lower than the installed total.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H14DSG-O-CPU motherboard slots?

Yes, the kit uses the exact 288-pin DDR5 RDIMM form factor that the board requires; it is not a UDIMM or SODIMM.

What is the correct population order when installing both 128GB modules?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first.

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

No, the RDIMMs have no onboard firmware or battery; ECC error correction and registered buffering are handled by the memory controller during normal operation.
