96GB DDR5 RDIMM for Supermicro H13SSF

This 96GB DDR5 4800 Registered ECC module is built as an exact-match upgrade for the Supermicro H13SSF motherboard. It uses the 2Rx4 rank organisation and 1.10V voltage that the platform's memory controller expects. The 288-pin RDIMM form factor fits the server board's DIMM slots without adapters.

Registered ECC limits and population rules

Registered buffering offloads the memory controller so every populated slot can run at the rated DDR5 4800 speed, while on-die ECC corrects single-bit errors before they reach the operating system. The motherboard manual defines the approved DIMM population order and maximum supported capacity per channel; exceeding those limits will prevent the system from posting.

Capacity headroom for dense workloads

A single 96GB module provides substantial memory headroom for virtualisation hosts, database buffers and large-scale analytics jobs that benefit from keeping hot data in RAM. Workloads whose working set grows beyond the installed capacity will spill to slower storage tiers and see increased latency. Buyers needing more total memory must verify the board's maximum supported capacity and slot count before adding additional modules.

Questions about this item

Should I pick the 96GB 2Rx4 kit or a different capacity for my Supermicro H13SSF?

The 96GB kit uses two 48GB 2Rx4 Registered ECC modules at DDR5-4800 CL40 1.1V, matching the board's required rank, voltage, and timing so the memory controller recognises full capacity at rated speed.

What does the DDR5-4800 CL40 rating deliver once installed in the H13SSF?

The modules run at 4800 MT/s with 40-cycle CAS latency at 1.1V, giving the bandwidth and latency the server's memory controller expects for stable full-population operation.

How does the 288-pin RDIMM interface and ECC registration affect real-world limits?

The 288-pin Registered DIMM form factor with on-board ECC lets every slot run fully populated at 96GB total while correcting single-bit errors, preventing silent data corruption under sustained server loads.
