Exact-match DDR5 RDIMM kit for Supermicro H13DSG-OM

This 128 GB kit contains four 32 GB DDR5-4800 registered ECC modules built to the precise rank, voltage and timing the server's memory controller expects. It is intended for administrators upgrading a Supermicro H13DSG-OM motherboard to full capacity with validated components.

DDR5-4800 registered ECC limits and population rules

The DDR5-4800 (PC5-38400) standard runs at 1.1 V with CL40 latency and 2Rx8 organisation; registered buffering allows every slot to be populated at full rated speed, while ECC corrects single-bit errors in flight. Your board's memory-population rules dictate which slots must be filled first and the maximum capacity per channel, so the kit will only operate at its rated specification when installed in the approved order.

Verify manual for supported capacity and slot order

Before ordering, consult the Supermicro H13DSG-OM manual for the exact supported capacities, approved DIMM population sequence and installation steps, because server memory support varies by model and BIOS revision. Buyers needing a different total capacity, a different rank configuration or non-registered modules should look elsewhere.

Questions about this item

Should I choose the 4x32GB kit or a different capacity for my Supermicro H13DSG-OM?

The 4x32GB kit provides 128GB total capacity using four 2Rx8 registered DIMMs. This matches the board's population rules for full-slot operation at rated speed.

What does the DDR5 4800 rating mean once the modules are installed in the server?

The memory controller will run the kit at 4800 MT/s with CL40 timings at 1.1V, delivering PC5-38400 bandwidth across all four channels when fully populated.

How does the 288-pin RDIMM interface affect what I can install?

The 288-pin registered RDIMM form factor is required by the H13DSG-OM; UDIMM or SODIMM modules will not fit or function in this server board.
