Exact-fit DDR5 kit for Supermicro H13SSF

This 512GB kit contains four 128GB DDR5-4800 registered ECC RDIMMs built to the exact rank, voltage and timing the H13SSF memory controller expects. It is intended for administrators who need the full 512GB capacity recognised at rated speed without manual tuning.

DDR5-4800 registered ECC limits

The modules operate at 4800 MT/s with CL40 latency and 1.10V, the standard JEDEC DDR5-4800 registered ECC specification. Registered buffering offloads the controller so every slot stays stable when fully populated, while ECC corrects single-bit errors before they reach the OS.

512GB headroom for memory-heavy workloads

Four dual-rank 2Rx4 modules fill the board's slots to deliver 512GB, giving ample room for large in-memory databases, virtualisation hosts or HPC datasets. Capacity stops at 512GB; workloads that need more memory per socket or faster transfer rates will exceed this kit.

Questions about this item

Is the 512GB 4x128GB kit the only capacity option for this DDR5 4800 CL40 ECC RDIMM?

The listing shows a single 512GB kit built from four 128GB modules. No other capacities or module counts are offered for this specific part number.

Will the DDR5 4800 speed run at 4800 MT/s on a Supermicro H13SSF with all four slots populated?

Yes, the registered ECC design and exact-match specifications let the memory controller recognise the full 512GB at the rated 4800 MT/s when all four DIMM slots are filled.

What does the 288-pin RDIMM interface mean for compatibility and maximum bandwidth?

The 288-pin RDIMM form factor fits only motherboards that accept registered DDR5 DIMMs, such as the Supermicro H13SSF, and delivers up to 38400 MB/s theoretical bandwidth per module.
