768GB DDR5 ECC RDIMM kit for Supermicro H13SSH

This 16-module kit delivers 768GB of DDR5-4800 registered ECC memory built to the exact rank, voltage and timing the Supermicro H13SSH motherboard expects. It is intended for administrators who need to fill every DIMM slot with validated capacity for virtualization, database or compute workloads.

DDR5 RDIMM population and speed limits

DDR5 registered DIMMs let the memory controller drive all 16 slots at the rated 4800 MT/s, but the board’s population rules dictate which slots must be filled first and whether mixed-rank configurations are allowed. The 1.1V operating voltage is fixed by the DDR5 standard for this speed grade, so no manual adjustment is possible.

2Rx8 registered ECC architecture

The dual-rank 2Rx8 organization with on-die ECC and registered buffering is the single specification that determines compatibility; the H13SSH memory controller requires this exact combination to recognize full capacity and maintain error correction across all channels.

Questions about this item

Should I buy the 768GB kit with 16x48GB modules or a different capacity for my Supermicro H13SSH?

Choose the 768GB (16x48GB) kit only if your Supermicro H13SSH motherboard manual confirms support for 16 DIMMs at 48GB each; otherwise select a kit matching the approved population rules and maximum capacity listed for your specific CPU configuration.

What does the DDR5 4800 CL40 rating mean once the modules are installed in the server?

The memory controller will run the kit at 4800 MT/s with a CAS latency of 40 cycles at 1.1V, delivering the rated throughput and timing the board expects when all 16 slots are populated with 2Rx8 registered DIMMs.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The 288-pin RDIMM form factor fits the H13SSH DIMM slots, while the registered buffer reduces electrical load on the memory controller so all 16 modules operate at full speed, and ECC corrects single-bit errors to prevent data corruption.
